funny someone should compare it to carbon fiber; I dont trust that material either

so my worry is this; I'm mounting them horzontally on mustache-like bars, so when riding the 'hoods' a lot of force is actually pushing them to rotate on the same axis as the band clamps and they tend to slip

I can keep tightening them, but I really do worry about cracking plastic soon....

humh, so the modern ones are plastic, time to ebay on old rsx 7 spd?
