4.0 out of 5 stars Chain Deflector, December 14, 2010

This product works well. The deflector part is metal, broad, and adjustable. I've had no problems with it and it was easy to place. I recommend it over the tooth fang style deflectors.

5.0 out of 5 stars Works but make sure it will fit for CX, December 10, 2011

Product is very well manufactured and I have no doubt it will work as designed. Unfortunately it won't work with cyclocross frames that have a pulley for the front derailleur blocking cable where it would clamp to. The pulley is in different places on different frames so YMMV but on my 2007 Norco CCX One it gets in the way. The Jump Stop would have to be installed so low to clear the pulley that it would be worthless. I've gone ahead and installed the Jump Stop on my Trek T100 tandem without issue. I've never had an issue with chain drop on that bike, it doesn't see the sort of jostling that the cyclocross bike gets, and now I suspect I never will have an issue.

I'll probably order another one and fit it to the girlfriends road bike. I'd get one for my mountain bike as well but it has a suspension pivot in the way.

5.0 out of 5 stars never worry again riding in San Diego, December 9, 2011

This N-Gear Jump Stop Guide/Watcher is really a 'cure all'! It is the best 10 dollars I Have ever spent. Very fast shifts to the low gear, with no worries. The absolute best!
