is there a similar topic on this? if there is my apologies.
i finally got around to stripping my bike down the other day when i noticed a small crack on the right hand side of my carbon handlebar about 1" long, on the left hand side too was a similar mark just not as developed. on inspection i realised they were caused by my gripshifters it wasn't due to over tightening as i religiously use a torque wrench. so it looks to me like the gripshifters have instead of holding the bar nice and evenly, it's simply crimped it along the edge of were the damage has occurred and not very effectively around the rest of the bar.
the shifters are about three years old, the bar 8 months or so, never notice this on my previous bar.
anyone else had this happen? is it a known issue with the shifters? any help info would be greatly received.
