The Fly Bikes Rotar is a clean, simple bottom bracket kit built around high quality bearings, with CNC machined 6061-T6 aluminium cones and spacers doing the rest of the work.
It comes in MID 22mm, MID 24mm, Spanish 19mm and Spanish 22mm, so pick the size that matches your frame shell and spindle. A 1.5mm and a 3mm washer are included for setting the chainline and taking up slack.
