steve@banbury-trials Posted January 7, 2007 Report Share Posted January 7, 2007 68mm or 73mm ,you'll just need a spacer with the 73mm . get the widest bb you can if your going to run a wide rim like a try-all or echo and a magura brake as there won't be enough clearance between the crank arm and the brake piston .if there still isn't enough clearance take a few mm of the brake pad material .steve Quote Link to comment Share on other sites More sharing options...
