The Good: Very light weight, half the weight of the stock one on a 2013 specialized Enduro
The Bad: Chain ring bolts like to back out ( use loctite )
Ive been running gamut for the past few years and have never had an issue. I just replaced the stock
guide on my 2013 Enduro. Gamuts guide was half the weight and twice as strong. Super smooth and quiet, very easy to adjust
i also run gamut guides on my downhill bike and dual slalom bike. They have been problem free race after race.
