Strengths:    strong, NEVER drops chain

Weaknesses:    loudest chainguide ever. roller bearing/ jockey wheel seized up.

Bottom Line:   
Marketed as one of the quietest chainguides, yer right. This thing is loud. It didn't help matters when the bottom jockey wheel siezed up one of the sealed bearings, bearly 1 month in. Why can't bike companys that make stuff with sealed/cartridge bearings use standard sized bearings that can be bought at any bearing shop for a couple of bucks? Is it so we have to wait for weeks with no bike for a repacement $2 bearing, or is it so they can charge $20 for the same "special" bearing? maybe both.
Probably a good thing for a "downhill only" bike because I have NEVER dropped a chain, but if you wanna ride trails + tracks get something quieter, it will ruin yor ride.
My cheapo MRP knock-off I got with another frame I bought is so much quieter, but not as strong.
I'm not impressed by this product, I paid top dollar for it (as you do in australia) cause it claimed to be the quietest on the market. It's not.

Strengths:    Has just kept on going... has survived rock ledges, logs and rails a plenty...

Weaknesses:    Set up can be tricky.. my guess is the nuffies who ragged this unit did so koz they were unable to get it aligned correctly..
I ended up making my own teflon rollers to replace the nylon std units...


Bottom Line:   
OK so it's old school, $hit this unit was around way before the E13 systems and still holds it own...
Would i spend the $$$ on it if i had to shoose between it and the E13... er... maybe not...

Strengths:    works good for first month in dry conditions.

Weaknesses:    bad rollers , bad berings, loud, cheap plastic, out dated

Bottom Line:   
This is one of the worst bike products that i have used. The thing is kind of a pain to set up and if you don't have the mounts on the frame the inside boomerang comes loose on the BB cup mount. I tried locktite on the BB with no success. Initially the guide was a little noisey but worked okay. But as soon as you get into the mud the crappy rollers ceize up and they wear out in about two runs. I can't find any replacement rollers/berings so i am forced to find a new system. the price was pretty high considering the crappyness of the guide. I've ridden my friend's P.2 with the infamous truvative box guide and it was smoother and more reliable. This thing is not worth the money. don't by it unless it comes on your bike. Just ride it till it breaks and get an evil. I've heard many good things about them.

Strengths:    not a friggin one!

Weaknesses:    the whole system blows!

Bottom Line:   
Please, please do not buy this piece of junk system! Do not waste your time. It is a piece of crap. It took me forever to finally get the thing to work, I had to use a hacksaw, and about 50 other tools to get this thing to fit right without any rub or other problems. So finally I got the thing working good. And it was working good for about three rides. Then as I am flying down the mountain, my cranks lock up. The cheap little plastic toy, top pulley had melted away and jammed up my chain so I could not pedal. I ended up having to cut the pulley off and it rode better with the chain rolling over the metal bushing. This thing is really loud and noisy too. It sqeaks like an arthritic woman's fake hip. It drove my riding buddies nuts. So I broke down and got my self an e 13 guide and it worked well, and then I eventually went all out and got MRP's top of the line. MRP is the the best by far. I guess you get what you pay for. My MRP went on without a hitch, is much quieter and the pullies are super heavy duty. Everything about it is heavy duty. If you like to ride on piles of crap, then MR Dirt Gizmo if made for you. Because that is about as well as it works. If you are at all serious about the products you ride, get an e 13 or better yet get the MRP.

Strengths:    Keeps the chain on the ring, strength, has both ISCG and bottom bracket mounting options, looks good

Weaknesses:    none really if you take the time to set it up properly

Bottom Line:   
I like this chainguide better than the MRP. It is better built and less likely to explode when you case a boulder. Sure, it can be a little tedious to set up, but what isn't on a downhill bike? Anyway, it is worth the extra effort to get the chainline right. (If you are not up to the task find somebody that is...;P) I've never dropped a chain with this set up and I cringe at the thought of what kind of catastrophic crash I'll have to have to get it to drop.

Date Reviewed: January 6, 2003

Strengths:    -Solid
-Thick dual bashguards
-The chain goes through tunnel-like sliders making it impossible to fall off the chainring.


Weaknesses:    -A little noisy but who cares (you only notice the noise when you're not riding down the mountain)

Bottom Line:   
If you take a bit of time to adjust the friggin thing, it'll work perfectly. I've never lost a chain with it. I set one up on my bike with cromoly cranks and DH spider and it works perfectly. I've even set one up on a bike with Truvative cranks that had the holes for the granny ring. Listen, they don't give you little spacers for nothing! Take a bit of time to putz around with it and it'll work!!! Remember, DH bikes are a pain to fit anything because of weird designs and such. Plus, if you're b!tching that your cranks don't fit...get REAL downhill cranks then. If you have the 2001 guide, get the newer sliders with the rollers in them. It works better.

Sucks much goat nuts. I am looking very hard to find a metal replacement for the rollers, but have come up with nothing. Any ideas??? Please email me with any information on how to upgrade this POS. The company website sucks and has no email address, figures...

Bottom Line:   
I have never had my chain drop while using this device, even when the bikes being thrown around quite hard. If you never want your chain to come off then you could'nt go far wrong with one of these. On the downside, it comes as standard with plastic on plastic rollers which suck, and wear out after a few weeks. After getting through a few of these I got hold of a ballrace kit for it which lasts a lot longer but costs an extra 25 quid here in the UK. Mojo Suspension are the importers of Mr Dirt in the UK and supply the ballrace kit. It's essential if you own and use one of these devices.

Strengths:    - Looks good.

Weaknesses:    - plastic guides versus rollers for chain
- only secured by bottom bracket cup tightness


Bottom Line:   
DO NOT BUY THIS GUIDE FOR USE WITH RACE FACE NORTH SHORE CRANKS!!!!!!!!!!!!!!!

IT WILL NOT WORK PROPERLY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Save yourself the time and frustration I experienced. The manufacturer has recently learned that due to the way the NorthShore cranks are set up with their granny spider it will not mount properly. You wil continually drop your chain and experience the guide rotating if you try.

Strengths:    ~Strong as all get out
*I can smack into anything and it's great
*Sprocket stalls? you bet
*Sprocket grinds? probably, i havn't tried
~Keeps the chain on great
*If the chain does fall off (has only once for me),it puts itself back on!!
~Cheaper than MRP


Weaknesses:    ~Loud, that's it

Bottom Line:   
This is suuch a great deal. The only way it could be improved was if it was quieter. Everyone has MRP, but I don't see why. Maybe for racing because it's lighter, but it's also WAY weaker, my friend bent his boomerang on his MRP when his chain slipped??? what's that??? my chain slipped once in the skate park when i slid out, and it put it's self right back on when i pedaled. It's great.

Date Reviewed: November 21, 2001

Strengths:    simple but effective
good strong base plate design
holds the chain on most of the time
less annoying than the cheaper chain guides with gay orange plastic rollers with crappy rollerblade bearings in them
easy to fit to bottom bracket


Weaknesses:    noisy, lots o' friction, hellish expensive at retail price, a lot of similar products out there at a cheaper price
pieces that guide the chain are relatively narrow, and dont allow for a lot of adjustment
the older version of this product comes with plastic pieces, which wear away and look terrible after a while
bb fitment may come loose, so the chain device swivels around when youre riding


Bottom Line:   
quite good, but i would prolly buy cheaper stuff in future, or shell out for an mrp
