We're so pumped about our new Lightning clamp! This Lightning Clamp has our bolt cut out for lighter weight, while using aircraft grade aluminum for extra strength. You will have no trouble finding a colour with 9 to choose from. Included with this Triple Clamp is a shim system used to run Standard (31.8mm) bars. If you are using Oversized (34.9mm) remove the shim and you will be good to go.
