Any one using the formula B4 pro with shimano rotor?
Or should I just get a adapter to convert my hub to 6 bolt?

How thick is the Shimano rotor?

Formula rotors are only 1.8 mm thick. If Shimano are 2.0 mm, you may have clearance issues with new pads. Also, is your B4SL 140 mm rear? Does Shimano make a 140 mm rotor?

PS. If you decide you'd rather just sell your Formulas, I'll take them!

should be no problem, just push the pads back in further
