Submitted by EarthJourney a Weekend Warrior from MI, TN, GA
Date Reviewed: June 26, 2009
Favorite Trail:Anything in the mtns.
Duration Product Used:More than 3 years
Purchased At:Came on the bike
Strengths:Great shifting (in dirty conditions) - seems to be bombproof by my way of thinking.
Weaknesses:NONE! I'd buy it again in a NY minute.
Similar Products Used:XTR
Bike Setup:'96 or 97 GT Tequista
Bottom Line:It's over 10 years old - granted used primarily on the weekends only - but this STX RC has been through hell and back (as has the bike). I'm big (wt varies from 225 - 235) and I ride HARD. This derailleur has taken all I've thrown at it and asked for more. To top it off - the care I've given it hasn't been very good. Several folks have given it low marks - ??? Friends w/higher end bikes consistently had more issues w/their derailleur - I've never had one (and I rode more consistenly and harder than they). I've also got a road bike w/XTR and it's far more tempormental than the STX.

Favorite Trail:Atacama Desert - Chile
Duration Product Used:More than 3 years
Strengths:Unbreakable! It has been shifting the gears of my '98 Cannondale F700 for almost 10 years. Occasional cleanning and ajusting (every 200 km or so). Precise and everlasting. This product line is outstanding: I also own STX RC hubs and I have never seen anything that rolls as much as these.
Weaknesses:Hardly anybody is familiar with this derailleur here: no market value (but, hey, who's selling??)

Favorite Trail:MoMBA
Duration Product Used:More than 3 years
Strengths:Lasts forever.
Weaknesses:I have both the STX and the STX-RC. The STX is in better shape right now, but it has the nut style cable pinch, instead of the 5mm allen bolt that's on the RC and is common now.
Bike Setup:Kona Fire Mountain ('98), Haro Escape ('98)
Bottom Line:This thing last forever. It's not officially 10 years old, and it shifts great. I took it out two days this weekend, with hard climbs, puddles, rocks, and never missed a shift. As long as it's set up properly, I can't find fault with it. It also has a smoked metal color, which looks sweet, even better than the current shifters.

Purchased At:Stock on my 1996 GT Ricochet - D'Ornellas Bike Shop (1996)
Strengths:Durability, weight, colour, clean & crisp shifting.
Weaknesses:None.
Similar Products Used:Shimano Deore XT.
Bike Setup:1996 GT Ricochet
Bottom Line:This review is for a *Shimano STX* rear derailleur, it does not say "RC" (racing) on the sticker on the derailleur. It came stock on my 1996 GT Ricochet, it has over 10,000kms on it and has been 100% trouble-free. The silver colour blends in well with the rest of the bike, it has given me years of clean & crisp shifting.
Bottom Line: This rear derailleur is just as good as my Shimano Deore XT on my 2001 Trek Fuel 90 Disk.

Duration Product Used:More than 3 years
Bottom Line:This came on my LTS in about 1997-98. It shifts about as well as an XT. How do i know? I have an XT deraillieur now, and i compared them, this is what i found..

the colour is different
the spring on the XT is just slightly stronger, or it could be my imagination
the bottom plastic wheel on a XT has a sealed bearing, and the STX isnt. I dont have a weight scale, but im pretty sure they are nearly the same weight.

in other words, people who have had problems with this stx part and tell you that you need to go to LX or XT have

#1 no clue how to properly adjust a deraillieur (lousy shifts)
#2 do not have things tight (falling off twisting etc)
#3 genuinly have really bad luck, because essentially your buying XT parts before they were called XT.

If you have an older bike that needs a decent shifter, buy a STX it`l cost you nothing and it should work well as long as it isnt damaged

Purchased At:Gooch's bike shop
Strengths:Sleek design-not too bulky. Has little chainslap when adjusted properly. Had the part for 7 years and still works well after daily riding and standard tuneups.
Weaknesses:Hard to tuneup on the fly and needs expert tweaking for crisp shifting. Better for lighter riders on moderate trails.

Bottom Line:Came with the bike and has worked well with daily use. Keep it if you're a light rider mostly into moderate technical trails or touring. Forget it if you're a heavier rider into thrashing technical terrain or an advanced xc trail rider- get upgrades (or have a whole other bike for that).

When i attempted to move it back to the normal position the two lower (what should be lower) guide wheels and bracket snapped off and when i picked it up off the ground the guides looked like a butterfly. if you want to live to ride another day dont but this piece of crap!!!!!!!!!

Strengths:Price.
Weaknesses:Broke second ride out.
Similar Products Used:XT, LX, Deore
Bottom Line:What a POS! It was a bit hard to setup but after that shifting great (for about 1/2 a ride). Then the problems started. For some reason it grabs the chain and temporarily jams the rear wheel. The worst case was going downhill at 40 MPH; talk about scary. Then when I was cranking up a short steep hill the thing jammed my chain totally locking the rear wheel. Couldn't get out and rolled backwards down the hill on my butt (luckily no one was around). Had a look at it and the limit screw stop (where the screw actually pushes against the der.) had snapped right off allowing it to go fully into my rim. Taking it back today.

Purchased At:Schwinn Moab3
Strengths:Strong and clean shifting.Works with both Shimano and Suntour topmount shifters and thumbshifters in index and friction mode.Low cost replacement for upgrading vintage mountain bikes.
Weaknesses:None
Similar Products Used:Shimano XT Deore 8 speed derailleur
Bike Setup:1993 Scott Unitrack w/ Unitrack LF fork/XTR
1990 Specialized Rockhopper/XT
Bottom Line:The STX R/C 'IS' the former Shimano XT 8 speed derailluer.
Parts are interchangable with the XT.
Placed side by side,there is very little cosmetic difference between the two derailluers.
The only differences between the STX R/C & XT is that the STX derailleur body is polished with the STX sticker.The XT version has the black wrinkle finish with printed XT logo.
Also the 'SIS' is stamped on the STX cage while the 'SIS' is silkscreened on the XT cage.
Performance wise it's the same derailluer.Clean shifting and strong.I updated this derailluer with the Bontranger/Titec titanium hanger bolt and cable bolts and replaced the original Shimano ceramic pulleys with Shift Biscuit alloy pulleys.The result is a lightweight bargain shifter.
The STX is a bargain replacement derailluer for those who want to replace the hard to find XT derailluer on their old-school rigid
mountain bike.
If you want a good derailluer cheap,the STX is a former race proven design.If you want to cough up lots of cash for a beat up original XT derailluer on EBAY so you can be cool with the XT crowd,feel free.Only the ones who know better will laugh at you.

Strengths:Looks good, shifts well
Weaknesses:None
Similar Products Used:Shimano (up to LX)
Bike Setup:Trek 6000 ('99 spec). Came on bike. Bottom end 'good' bike.
Bottom Line:I've ridden weekly since 1999, and had no probs. I get the bike serviced regularly, and keep it clean and lubed. I've had no probs shifting at any time, and the only time it protests is when i over tourque the system while uphill shifting. I understand that it is not a LX or an XT/XTR, but im not a x-country racer, and i don't push myself too far and fall off and crash. This is my style of riding. SO if your no a hard core mud-nut (like me), this part should last forever. If you want to go hard on trails every day, buy xtr

Strengths:superior airspeed, armour, firepower and manuerverability
Weaknesses:lack of diving speed, armour, inferior airspeed, shoddy construction
Similar Products Used:none
Bike Setup:does not apply here
Bottom Line:to the fellow who states that the mitsubishi A6M zero was pretty much the superior fighter aircraft in the second world war, you should do YOUR homework.

here's a few stats on the A6M3 model 22--the top speed was 336MPH at 19685 feet. it carried two 20 mm cannon and two 30 caliber machine guns. the range was not equivalent to many allied aircraft and i am relatively sure that the service ceiling was lower.

in comparison, the P 47 thunderbolt carried EIGHT fifty caliber machine guns and would run 467 MPH. its service ceiling was 43,000 feet and it had more armour and a much longer range than the zero.

the focke wulf FW 190 carried two machine guns and two cannons as well, but could be fitted with two heavier anti tank cannon. its speed topped out at 408 MPH and the sevice ceiling of the 190 was about 34,000 feet.

other fighter aircraft from the second world war which were superior to the zero were the F4U corsair, the P 51 mustang, the grumman F6F hellcat and the supermarine spitfire. although the zero might have had better performance than american fighters such as the curtis P 40 and the grumman F4F wildcat (or the brewster buffalo--remember the early stages of the battle of midway?) in the early stages of the conflict, its advantages were negated by the advent of american and british fighters i've mentioned above.

sir, before you tell me to do my homework, you might want to do some reading yourself. i will stand by my statement that the shimano STX RC rear deraillieur is a cheap piece of crap and should not be the choice of a competent rider who rides regularly and hard.

Weaknesses:Pulleys wear a bit faster, but can be fixed with some new pulleys.
Similar Products Used:Everything else Shimano besides XTR
Bike Setup:Kona Stuff
Bottom Line:For the 6 years that I've had this thing, it has worked flawlessly with the occasional maintenance intervals. The only major difference with this and other Shimano derailleurs is the weight. This things performs just like the others higher up in the chain. When this thing is set up right, it is surprisingly smooth and has never given me a problem shifting uphill. I figure all the people who have problems shifting uphill are torquing their drivetrain way too hard during shifting which you shouldn't be doing anyway. Most of the people having problems after hitting a rock with the thing... well what do you expect? Any derailleur will break if you hit it hard enough I guarantee you that and besides you're not picking a good line if you're banging things around. This thing works, enough said. And to the fellow and his comment about these things being made out of "zeros"... Well Zeros were pretty much the superior aircraft during WWII. Do your homework next time.

Date Reviewed: February 28, 2002
Favorite Trail:Haw Ridge
Duration Product Used:More than 3 years
Strengths:It has all the adjustments needed on a rear derailer.
I personaly recommend that you take a tiny allen wrench, remove the cage, and put the chain tension spring in the firm position. Yes, it is removeable. Yes there are two settings.
Weaknesses:It came stock with the Light Action spring.
Get a Powerspring to replace the original return spring.
Don't follow the directions on the package for instalation. Doing so will slightly bend your spring, thus reducing it's efectiveness. Instead, make a hook out of coat-hanger wire and use this to pull on the end of the spring to facilitate installation.
Similar Products Used:Shimano Excage
Bike Setup:Gary Fisher aluminum hard tail frame, Marzochi Z4 Flylight Air, 1995 Shimano 8speed integrated controls
Bottom Line:This is the one part of my bike that I haven't replaced.
The bike came with gripeshift. Due to the lack of a return spring in the shifter the "system," briliantly engineered by Gary Fisher, did not reach the three smallest gears. The shop put a aftermarket Powerspring in the rear derailer. Shortly after that I got Shimano XT controls and haven't missed a shift since. The year that I got the bike,1995, Shimano was hypeing it's new "light action shifting." I recomend everyone change the spring in his rear drerailer for a Powerspring.
I like a firm shifter lever across the whole range of gears.

If you're not a real hardcore rider, the STX-RC will probably last forever. however, if you do any real trails it will only last a season at most before you start having problems. It took one nice crash for me and i never got it to work well since, just because it bends so easily. Good value, but you'll be looking to upgrade soon.

Bottom Line:this garbage came with my bike. it was a total piece of crap, it was ok for awhile but quickly went to pot after i put a few trails on it. it would not shift going uphill at all.. just click endlessly and would always screw up my timing or my line uphill. the XT will easily shift anytime. by the way, my front derailer was a stx also and did the same thing till i switched to a single ring in front. the final ride for this derailer came when one of the pulleys broke in half (they are plastic and do not have any bearings) i switched out the wheels with some nice pullies, and later to my great surprise as i landed a small jump, the cage bolts came loose causing the cage to seperate and shear off about 10 of my spokes. well it was prob my fault, but it seemed like it was fate that this piece of crap would, as a final act of defiance, destroy not only itself but a bunch of spokes and one rim. if u have stx garbage on your bike and you do any riding that makes you break a sweat... get rid of it now.

Bottom Line:when shimano makes it bad, they make it BAD.

if there are any of you around who still have these things on your bikes, you must not be riding so much. my stx derailleur got very, very sick within a thousand miles of commuting and thrice-weekly rides in golden gate park and the marin headlands. they must have made these things out of recycled zeros. (do you chimps know what a zero is? it is a world war two era japanese fighter aircraft)

shimano does'nt make stx or stx rc anymore, so this is a good thing. how they got away with masquerading this crap as a viable entry level component group is beyond the realm of my muddy dreams. the sad part of it all is that this junk came standard on a lot of relatively expensive bikes, especially earlier model suspension bikes.

get rid of your stx stuff, replace it with at least lx and go riding.

Bottom Line:The shifters and Derailleurs came on my bike. I had an STX-RC crankset as well, but hit a large rock and bent the spider. Had to upgrade to an 8 speed crankset. The shifters and derailleurs work flawlessly, although a bit noisy. Easy to adjust, and they stay adjusted. They work well even if muddy. These derailleurs work fine for 8 speed. In fact, they work so well, I can not justify spending the extra money to upgrade to 9 speed. The downfall to this, is that no one is making 8 speed any longer, therefore one must upgrade of these break. I will ride them till they are toast. I have no clue what the value of these STX-RC parts are, because they came on my bike. I do know that they work tremendously well... except for the STX-RC crankset. I weigh 230 pounds, and I did notice some flex in the cranks at the bottom bracket area, but I am also riding a Reynolds Steel frame... flex is to be expected.

I've since upgraded my drivetrain to a 9 speed and am running the as reliable XT rear dr. The STX-RC is the best bang for your buck. I've raced 4 races with it without having any problems. Save your money and sink it into your front derailer and cranks, where you'll see the most difference.

Strengths:Cheap but pretty darn reliable.
Weaknesses:Can sometimes skip gears. Ghost shifting. Weak materials!
Similar Products Used:Altus
Bike Setup:Diamondback ascent ('94), stx all round.
Bottom Line:I have had this bike for ages now and all the components on it are the same as when i got it, (except for the rear wheel and seat which were stolen!) The stx rear der seemed to always suffer a bit more than the front and skipped gears, especially when going over bumpy ground. However the bike is 7 years old and the rear der has only just packed up. This is due to the weak material used in the fixing of the mech to the hanger (stretchy aluminium). If you can still get these mechs then they are perfectly fine for people who don't ride too hard, but you get what you pay for. The altus i had broke in weeks not years. My new bike i am building will have LX or XT instead.

If you are a beginer rider and it comes stock on the bike you want, I wouldn't not get the bike because of it. However, if you are a rider of any skill level that need a new derailleur, go with Shimano Deore, or anything above. This is not worth the money to go out and seperatly buy it cause it does not perform well unless you constantly tine it perfectly.

At the beginning of every ride, it tends ignore me for a while. It won't come back to life until I manual shift it at the joint. After that, it tends to work pretty well, even uphill. It does tend to miss gears periodically but I guess that's to be expected for the inexpensive price tag.

I have a 98, and I gotta say I'm impressed with it, it has pretty smooth shifting, looks nice, and with a few miles of stairs, trails, and streets each week, has developed very little play and shifts great when it's set up right. I said it was a bit loud, but who really cares, even if XTR shifts smoother I'd be babying it because of it's price. I've used it with both cheap grip shift and better pistol shifters, with no problems. For 35 clams, I'll beat the hell out of it and buy a new one in a year or two. I think this is the derailleur of choice from Shimano.

A freind has an LX, and mine shifted better. His wasn't quite adjusted right. Now that it is, they shift the same. STX-RC is a tad hevier than LX. When mine retires, it will be replaced by LX or XT.

Submitted by Phil... a cross-country rider from Alaska
Date Reviewed: January 24, 1999
Bottom Line:

To bad there isn't a review site for the STX rear derailleur, so forgive me as I put it into the STX RC catagory...My STX has needed no adjustment, other than the normal stuff like cable tension to keep the sis shifting sync'd after the cable stretched... not the derailleurs fault. When I put a new rear wheel on I had to readjust the throw limiters to keep it from shifting over the 30 tooth cog and into the spokes... again this was normal. (due to slight differences in wheel dish). Once adjusted it stays that way. I am using this derailleur with Gripshift, and have yet to experience the difficulties of sluggish shifting I remember others complaining about... I don't use a bassworm, or nightcrawler either. However, I might buy one just to keep my cable housing cleaner inside.Th STX has more steel parts in it than the STX RC so its a little heavier.The STX RC is really quite similar to the LX part (I have held them side by side) it was a few bucks cheaper, and was polished silver, while LX was black. The STX, and STX RC rear derailleurs are good values, and my STX works fine. I keep thinking about upgrading it since the 99' XT is sooo beautifully sculpted, and cool. But the STX continues to work so well that I can't justify the $50+ for the XT.... maybe next year if I can wear it out... Not likely. I have a 1988 shimano light action derailleur, on an old commuter bike I ride, that still works...I replaced it once, then broke the replacement...5 stars for being inexpensive, and transparent ( works so well I don't notice it).

I have several bikes, including a Fisher, Specialized and Basso (roadie). I recently bought a used full-suspension mountain bike with mostly STX-RC stuff on it, including the rear deraileur and trigger shifters. The rear deraileur shifts great!!! Better than my other bikes .... I don't know where so many people get off saying how poor its performance is. My deraileur is not particularly clean, gets ridden pretty hard in many different conditions and shifts fine -- even under power. It's quiet and shifts firmly. I'm sure if I spent $90 for a different deraileur, I'd thumb my nose at the less expensive STX-RC components to help justify the expenditure too.

Bottom Line:

Not by any means great, but not terrible either. I've put over 2000 miles on mine and it still works. I've racked it on roots and rocks and crashed on it several times and it survived fine. It didn't shift very accurately (if at all) under load when mated with twisty shifters, but improved when I upgraded to XTs. I also had to change the original spring to an after-market upgrade because it wouldn't up-shift after a while. I'm finally upgrading to XTR since Supergo is giving them away for 50 bucks, but the STX-RC was definately serviceable and I'll keep it for a backup. 3 chilis

Bottom Line:

My '99 Specialized is in the shop at this moment having my STX-RC rear derailleur and shitty Alivio front turd replaced with an XT front and rear set (including shifters). I had been riding an LX rear 'd' for a while on another bike, and when I bought the new Specialized I couldn't believe how sloppy the STX-RC was. Sometimes it would shift fine, other times it was rough, other times it wouldn't shift at all - no matter what kind of load was on it. Maybe I got stuck with a bomb, but I'd rather get the upgrade over with - it was gonna happen anyway. Anybody wanna buy this one?

She does her job well. I have it with a 24 speed setup, shifts well, even under load. Clunks and chunks sometimes, but it still does change.

Anyway, it does the job. - - - - - - - - - - - - - - - - - - - - -

Bottom Line:

I don't like it. I have 7-spd so I cannot go LX or XT very easy. When combined with a grip shift, this combo is terrible at shifting, under any decent load or uphill, because it simply isn't accurate enough. But I've had it 2 years and it is still going, so what can I say. 3 chili's I guess. I think that is where it should be, for price and endurance.

Bottom Line:

I've been riding on an STX for almost two years now and dispite several hard crashes its still intact. I have also upgraded it with an SRP breakaway bolt Which has made it lighter and limited frame damage. the shifting is reliable although it can get sluggish which is usually a good clue that it needs an overhaul. Alot of the reviews I've read here comment on the shifting in a fair way. However those which simply write the rear mech off as crap without any justification and then spout off about the great Gods of XT + XTR are obviously either snobs or spoilt little gits with rich daddys. The fact of the matter is that the STX and STX RC offer good function and value for money which are important factors to consider if you are not on a huge budget.

Bottom Line:

I rode an STX-RC rear derailleur for 3 1/2 years. I do allot of riding over rocky terain, the crashes can be tough on the derailleurs. I've had a number of hard crashes in that time, and the derailleur took them all. It shifted fine in the winter mud season, and seems quite durable. I now have an XT rear derailleur, it's quite a bit lighter, but it doesn't shift any different than the STX did. The STX is a heavy, but a good value. A crash can take out any rear derailleur, if you crash alot, get a cheap one.

Why r u guys complaining...? Number one rule of thumb... you pay peanuts

don't even have the skill yourself... try smashing your balls on the rough
terrain and see how it does... dropped off our squashed... r u upgrading it

All in all... the STX RC is value for money on the entry level... be satisfied!

Both the STX and STX RC are reliable and precise when shifting. My hardtail is equipped with STX and has 1500 miles on it with no problems. My Haro full suspension bike has about 600 miles on the STX-RC with no problems. They seem to shift ok when under power, which is more than I can say for the front derailleurs.

The Shimano STX is realy tough, I ride VERY hard and i think the
derailleurs are the only parts of my bike that actualy works, and that's after six months! The problem is that they are too slow and you can't shift when your going uphill. The next one's will probably be XT.

Bottom Line:

This thing came with my Rockhopper and initially I thought it was pretty good. I didn't do much off-roading then but now I've started to tackle the trails and found that shifting from this derailleur just doesn't cut it. It is way too slow and won't shift well under and pedal pressure at all. If you're just looking for a derailleur for the road and flat trails then this is ok, but if you're looking to climb hills save yourself some anguish and spend the extra cash for an XT.

Bottom Line:

I've had the STX RC for almost two years and it works great. Click through all 8 gears up or down. The unit requires little or no maintenance. It is true that shifting is not possible under high pedal force, but then again, no derailleur is intended for that. I usually either guess what gear will be necessary before starting up the hill, or accelerate in the middle of it and then shift while the bike decelerates. Until Shimano comes up with a clutch, I don't think there will be any advantage in having an XT over an STX RC.

I've had it for over a year now, it Came with my GT Pantera, once I bought the bike, i was gonna upgrade it, but decided to give it a wirl, and i was surprised at how well it shifted, 8 speeds, with the rapid fire shifter. if oiled and tuned, it can perform like an XT. Very durable, besides what these other guys say, i've crashed several times, HARD, i broke my knee, and the derailluer hanger on the frame, but the derailleur was intact except for the scraches, i heeled, replaced the derailleur hanger, and it shifted perfectly, I DIDN'T EVEN HAVE TO ADJUST IT!! when i start the new XC racing season i might replace it with an xt unit, MAYBE. But i'm currently happy with it, and i've won two races with that derailleur, and i'm not that good.

This came stock on my Rockhopper, and I've been using it for over two months now. I'm no hardcore-biker, but have put it through the paces many times on the trails. On top of that I have crashed HARD at least twice and the thing still is good as new.
The only reason I would upgrade this derailleur is for the status of an XT or better. I can't find anything wrong with it, so 5 chillies.

After seeing that my friend had one for 4 years and still functions perfectly, i decided to get one for myself. Haven't installed it yet but already know that it'll be a big improvement for the bike. It's the 97' model and the spring is much stronger than the Shimano SIS derailleur that I had. Derailleur body is also full alloy and not part plastic like the Acera X, Alivio, etc. Not to mention the color looks great too. STX components have this really nice light champagnish polished color which looks great. Oh yea, also got it for $16 brand new at the MTB Marketplace.

THE STX-RC DERAILLEUR IS VERY SIMILAR TO THE LX, THE ONLY DIFFERENCE IS THE PAINT JOB AND THE SEALS(AT SHIMANO'S WEBSITE. THE DERAILLEUR PERFORMS WELL SHIFTS WELL AND DOES WHAT A DERAILLEUR SHOULD DO. RIGHT ABOVE HIS REVIEW LEE SAID THAT IT HAS A BAD SPRING BACK ACTION HE'S NOT WRONG BUT THAT COMMENT CAN ONLY APPLY TO THE 1995-1996 MODELS THEY GAVE A STRONGER SPRING FROM '96 SO IF YOU HAVE AN OLDER MODEL OF THE STX-RC JUST GET A NEW SRING DON'T GET ANOTHER DERAILLEUR!!!!!!AND OF COURSE IT ALWAYS TAKES SOME TWEAKING HERE AND THERE TO MAKE IT WORK WELL.

Bottom Line:

Shimano STX-RC RD-MC33 rear derailleur, came with a 1995 bike.
Return spring is too weak to work with Grip Shift shifters; a
stronger spring fixes this problem. After that, it works well
until it wears out (about 1+1/3 years of off road riding, not
very good) and develops enough pivot play to affect shifting.
Weight weenies might note that it weighs about 10.5oz.
