• Profile Racing is pleased to announce the arrival of the Outboard Bearing Bottom Bracket kit for Profile Race cranks. Outboard Bearings are larger, stiffer, smoother, and more durable that our existing Euro bottom bracket. We have tube spacers for 68mm, 73mm, and 83mm BB shells, however, we will have the rest of the common BB shell widths available soon.
