from Pontypridd,RCT, S.WalesDate Reviewed: November 16, 2007
Strengths: Strong, easy to set up, works with all 3 of my front chain rings. Stops chain jumping off. Pretty quiet. Used for over 10 years on various bikes with no problems.Weaknesses: Doesn't work with elevated chain stays. Early ones were noisy but the problem was solved with a different roller being used by manufacturer in newer models.Bottom Line: Works well with a single ring as well as a triple ring set up. I used it with an MRP, just to make sure, on another bike set up for DH and the chain never threw once. Also used on a XC set up. Again, no chain throwing off. If you ride and get fed up with your chain bouncing off, get one of these. Simple to set up and not very noisy, just a quiet rumble, especially now as the roller is a softer compound rubber unlike the rock hard orginal DCD's.
Favorite Trail: A few local ones!!!!

Strengths: it does work damn wellWeaknesses: not with a triple chainringBottom Line: this b1oody works but is is designed for 1 chainring up front, the roller is not wide enough for 3. look at all the pro who have them, they only have ONE chainring. why dont you people try reading the instuctions!!! moan moan moan moan moan, it is not going to do a job that it is not designed for is it.

Strengths: it was cheap
that's just about it, i'm afraidWeaknesses: it took 2 hours to fit
it's noisier than a menopausal pig that's hungry
IT DOESN'T WORK - it kept moving out of place, it made shifting hell, and when i covered it in petrol in wouldn't f**king burn up.
Bottom Line: It might be cheap, but that doesn't make it good value. It is just absolutely useless. The worst part I have ever bought for a bike (including a halfords own six speed sprocket). It wouldn't fit onto either of my two bikes without me having to bash it into place with a hammer. It didn't do anything to prevent chainslap on the 'cuda, and it didn't sort out my shifting problem on the saracen. Save your money for a proper bottom bracket mounted device and don't buy this piece of s**t.

Strengths: Light, simple and cheap. Nice Colour holds the chain quite well and stops it from completely dismounting.Weaknesses: The rubber wheel wears oujt if you ride in the same gear for a while and it can move around if you have a thin chainstay. Too be honest it is not worth the money it is much better to take away a couple of those valuable chain links!Bottom Line: Not worth buying unless you cannot take out chain links or you have money for a descent chain tensioner.

Strengths: Good looking, works ok (more below), awesome priceWeaknesses: bad when used w/ 3 chainrings, requires derailer adjustments afterwardsBottom Line: WOrks great if you set it up right. Since i only run 2 chainrings i don't have any of the problems that re mentioned here. At first it would cause my derailer to run too close to the cogs in high gear, but a few adjustments fixed that. Granted, it doesn't work w/ 3 chainrings, so slap it on a slalom or trials bike and have fun.

Strengths: robustness-imagine it wont break really. also simplicity means minimal hassle.Weaknesses: they didn't take into account that chainstay (what it mounts on) is not in-line with the chain; therefore the chain roller bit is all wonky and dislocates your chainBottom Line: always get a chain device that attaches to your bottom bracket or something which is inline with the chain (well near enough inline depending which gear you are in on the rear cassette). a good idea but executed badly. would be good if they had the bottom half kinda bent a bit (if u have had one u will understand me more!). also extortionate price for the lack of design (just paying for some patent probably) and there are no quality sealed bearings or nice cnc machined parts for the money. rip off.

Strengths: I've taken this thing through hell and back.Weaknesses: None, it makes a little noise, but i'm in a punk rock band, so i can handle noise.Bottom Line: I've had this thing forever. Its never let me down. Its super strong, makes my shifting cleaner, and i never have my chain bouncing around when i do big drop offs. I'm a trials rider, and i love it. I also do urban assault and alittle bit of DH type stuff. This thing is one of the best investments i've made.

Strengths: Silent
Looks good
Keeps chain on
Improves shiftingWeaknesses: NoneBottom Line: Maybe if you are a world cup downhiller, or have a pro team deal or something you are going to buy an MRP, but for the money this is amazing. it is easy to fit keeps the chain silent and stops it coming off. The only gear I can't get now is big ring at the front big ring at the back (3,1), which is a fairly dumb gear to use anyhow. If you are too good for this product don't buy it, get an MRP and go complain about how expensive it is.
THIS IS GOOD!

Bottom Line: This product is fantastic. People say it makes a noise, but if you take th bushing out of the roller, then clean it up, stick a mixture of LM grease and thin cycle oil on it (say once every 2-3 weeks then it will sound as if you don't have one on). If you also replace the rubber roller ever time your shifting starts to get poor, and you will be well on your way.

Bottom Line:
The last guy, Chris, hit it right on the head. I'm not pounding down Everest, but I run an XTR drivetrain and I expect the damn thing to work. I was on a two week trip in the south (dirt, gravel roads) and my shifting was also getting progressively worse. Finally took the thing off as per a friend and guess what? No more shifting problems. My drivetrain is silk now. Thank god I got rid of it. I'm not exactly sure what the problem is, but it doesn't seem to work well thru the whole gear range (particularly at the extremes) and basically results in a war between your rear derailler and the tensioner. Disappointing and not recommended.
