I am keeping an eye out for a set or even just a right Mavic Wishbone shifter. As I am thinking of using a 1x7/8 drivetrain, the left shifter would be nice to have, but not essential.
Tough things to find, Usually see loads of wishbone shifter parts at the York cycle rally (23rd & 24th june) in the saddlebag sale, never one of them a complete unit though otherwise I would have snapped em up.
