This svelte, alloy design is a great upgrade from the bulky plastic version that comes stock with your SRM unit. This two piece design installs easily to any standard 31.8mm handlebar. The alloy clamp also fits most winged bars, including the FSA K-Wing. SRM PowerControl head units slide on easier and are more secure on these alloy clamps. This clamp fits all SRM head units.
I had a hard time getting the PCVI head unit to slide onto the stock plastic clamp, but this one is perfect.
Agree with other poster, I bought this when the plastic one that came with mine broke - its much nicer than the plastic stock clamp.
This clamp works much better than the regular plastic one I had been using. It looks better too - much thinner profile.
