Strengths:    keeps chain on most of the time

Weaknesses:    flimsy, bends easily, makes annoyin noises in high gears due to chain rub, IMPOSSIBLE to set up as you have to tighten about 4 or 5 bolts at the same time, move one bit and the whole thing goes out of line. also, it sometimes lets the chain off and gets it stuck between the chain cage and ring, lucky its so easy to bend because it wouldnt come out otherwise, still takes ages though. not a good design.

Bottom Line:   
do not buy new, its WELL not worth it, about 25 quid. i wouldnt pay more than 10 for it. even better, why not get something to keep your chain on, like some sort of pulley wheel shaped device?

Date Reviewed: October 12, 2004

Strengths:    Cheap, simple, can be adjusted with normal washers etc.

Weaknesses:    Poor design, easily knocked out of line, takes ages to set up properly, chain makes annoying sounds in certain gears when it rubs on the nylon blocks.

Bottom Line:   
Pretty crap to be honest, but for the money it has to be expected. It looks like something out of a Meccano set or a GCSE engineering project. Not the best design by any means, but if set up properly and not whacked with a stray foot it does the job. Sometimes.

Strengths:    keeps chain on

Weaknesses:    CHEAP!! this thing bends SO easily. i'm glad i didn't pay money for it.

Bottom Line:   
well, it works, but if you catch it with a pant leg or something, it's screwed. period, it is really flimsy. but it works. i don't know what kind of value it might be because i didn't pay for it, but i was told it costs around 45-50 U.S. bucks. not worth it.

Submitted by Ken Ingham a Downhiller from Cardiff in wales

Date Reviewed: June 7, 2002

Strengths:    It looks pretty cool i guess

Weaknesses:    VERY hard to set up, one little knock means you need to re-adjust. chain rubs an awful lot. Cheap materials, says its strong but is weak.

Bottom Line:   
Dont even think of buying this, it may work well for a while but the chain will always fall off, and it will brake very easily, the cage metal is cheap, and the bolts and flimsy. Overall crap.
