    Submitted by enarburg a Weekend Warrior from Knoxville
    Date Reviewed: October 9, 2008
    Favorite Trail:Iron mountain
    Duration Product Used:3 months
    Strengths:Great for light duty use like commuting or XC.
    Weaknesses:Cannot hold up on rough trails. After going down a mountain for about a mile I noticed the derailleur had snaped off.
    Bottom Line:The derailleur can handle some of the mountain but not a constant beating. I would definitely purchase a more reliable derailleur if you like keeping a fast pace throughout a rough trail.

    Date Reviewed: August 21, 2007
    Favorite Trail:Majura Pines
    Duration Product Used:Less than 1 month
    Purchased At:All Terra, Manila
    Strengths:Smooth shifting. Possibly cheap, but probably not cheap enough.
    Weaknesses:Just weak. And slow!
    Similar Products Used:X.7, LX
    Bike Setup:Giant NRS3 with upgrades
    Bottom Line:The performance is just not up to it.. Its fine for easy riders, but once you're doing anything demanding (including riding hilly roads) the mech just doesn't shift fast enough. I've tried heaps of adjustments, but I think its just a weak spring. Also the mech bobs excessively when riding over rough stuff, so ghost shifting is an issue.

    I'm upgrading to an XT temporarily. Eventually I'll convert to SRAM X.9 to get the full performance out of my bike. I've been really happy with my X.7 set up on my hardtail.

    Favorite Trail:Devils Elbow
    Duration Product Used:More than 3 years
    Price Paid: $39.00
    Purchased At:pump n pedal
    Strengths:Decent price, easily replaceable.
    Weaknesses:Squeeky, changes HARD and LOUD, finding final adjustment can be a long process.
    Similar Products Used:XT, Altus
    Bike Setup:Gary Fisher Tassajara GS
    Bottom Line:The Deore doesn't seem to be durable as it's little cheaper sister the Altus. It changes Loud and Hard, not smooth like you'd expect (or hope). The 1st one I had Ate itself in a bad gear change so I tried a 2nd. If this one bites it (so far so good)...I'm gonna go with SRAM or maybe try backtracking into the Altus line.
    Overall...It does it's job, if not begrudingly.

    Strengths:It shifts
    Weaknesses:- Constantly needs adjustment
    - ghost shifts
    Similar Products Used:Altus, XT
    Bike Setup:2006 Marin Muirwoods city bike
    Bottom Line:I have taken this thing in for 3 tune-ups and everytime it is the same thing, take it for 1 ride and it needs to be adjusted. I think I am going to replace it with the cheapo Altus that came off my old bike. I rode that for two years and never touched it once. I can't really give a fair value rating because it was a part that came on the bike. But if I would have purchased this because it says "Deore" I would be pissed.

    Favorite Trail:geeknerd99@gmail.com
    Duration Product Used:Less than 1 month
    Price Paid: $20.00
    Purchased At:JensonUSA
    Strengths:Survived getting caught in spokes, which snapped my hanger. Still shifts fine. Maintains tension sooo much better than POS Acera RD that came with bike.
    Weaknesses:If you remove a pulley to install it, make sure you tighten BOTH pulleys after you're done! I found out the hard way when I jettisoned a pulley about 3 minutes into my test ride.
    Similar Products Used:XT shifters and RD, X-9 shifters and RD, both on friend's bikes
    Bike Setup:Frankenbike (Iron Horse Warrior Team SE) with new stem, handlebars, bar ends, grips, shifters, saddle, seat post, brakes, brake levers, pedals, crankset, FD, RD, tires, and soon a new fork and headset or a new set of wheels. Heck, why not both?
    Bottom Line:For 20 bucks, not bad at all. I'm sure there's better out there (XT sounds tasty), but I'm sure this'll hold me over. My bike weighs about 32 pounds for a hardtail (a lot is in the wheels), so I'm not worried about weight. Oh, and black is totally cooler than silver on my frame.

    Haven't been able to ride it rough yet, and I'm not sure about mud performance. Last 400 miles for me have been on the roads w/ my slicks, with 40 so far on this derailleur. I'll be back on the trails probably once or twice before it warms back up though.

    5 for value, a conservative 4 for overall (considering I had to reinstall the upper pulley, which is quite a bit like playing with a mousetrap).

    Purchased At:came with bike
    Strengths:strong, and sometimes very nice shifting
    Weaknesses:loud, sometimes problems with shifting, price
    Similar Products Used:XT, LX
    Bottom Line:If you are buying Derailleur for beginers it is really OK. I'm rideing bike 6 years and never let me down. After 2 years it work so good that was silent tlike LX, and shifting was so good that I didn't belive, but after 4 years rideing and 15 000 miles it start to make noise. On the havy duty when you trying to change gear if you not pick a right moment it has problem with changing. Now it cost a little les than SRAM X7 and that's a too much, and thats why I'm buying because cost 30$(25€) on sale and it has a great reviews on this site.

    Bottom Line:Over all if your a beginner and you DON'T crash then it's okay. But if you going to crash or put some strain on this then this is not for you. It came with my bike and not I have to get rid of it cause it's sucks. It'll get you from point a to point b, but it's going to be and ugly and frustrating ride for you.

    Duration Product Used:6 months
    Purchased At:OEM
    Strengths:Works for the first ride.
    Weaknesses:Constant adjusting. I actually was spending so much $$ on tuneups I took the Park Tool class to save my money. This derailler needs adjusting after nearly every ride. Must be spotlessly clean to function right. Cables need to be perfect to shift clean.
    Similar Products Used:SRAM X.4 and X.9
    Bike Setup:Motobecane 700 DS with Manitou Super Black Skareb and Cane Creek AD-12.
    Bottom Line:Don't skrimp on components!! This POS has only 600 miles on it and I spend constant adjustments on it after each 8 miles of blue groove. I will be buying a SRAM rear de and shifters for this bike.

    Bottom Line:This came stock on my Giant Yukon, it seems to have held up very well. It will probably last me another 2 more years until it needs to be replace. Deore seem to be tough components and built to last so i recommend this derailleur for the usual cross country rider or weekend warrior.

    Favorite Trail:Potowatami
    Duration Product Used:1 Year
    Purchased At:Came with the bike
    Strengths:Solid, full metal construction (except the gears), good shifter, preformance you would expect from a derallieur in this price range.
    Weaknesses:A little bit on the heavy side, not as precise in manufacturing as an XT or XTR (come on, what do you expect).
    Similar Products Used:Alvio, Altus, older shimano derallieurs on road bikes
    Bike Setup:2005 Trek 6500
    Bottom Line:If you are looking for a good derallieur for recreational riding then this is it. If you are a weight saving junkee, then maybee you shold think about XT or XTR. This derallieur is an economy version of the LX and XT derallieurs. When properly adjusted, it will function well. Some people say that it shifts poor and doesn't hold up and stuff. Bottom line:If you are a stupid retard who doesn't know how to preform a basic repair like adjusting/fixing a derallieur, or doesn't know how to ride properly, then don't buy this deraiileur and most definatley do not ride a bike on trails. I will give this derallieur 3 flaming chillis for value and the overall rating, because there are better things out there and there are worse.
