RR4 Front brake bore diameter What size is it? I have searched and not found specific data. I'm looking to relocate to the LHS clip on due to injury, can't use the OEM I've been told ! but if I can find a clutch lever with same bore size I can utilise that in place and dual mount one above the other. Akin to my mountain bike set up. This is first port of call in place of buying a K-lever for £830. Cheers
