Shimano has long continued their Dura-Ace 7710 Track Crankset which requires a threaded internal bearing bottom bracket with a 109.5mm Octalink V1 eight spline interface. Unlike it's road counterpart the BB-7710 Track Bottom Bracket features steel threaded cups and a hardened polished chromoly steel axle. It is designed to handle the high stress heat and power of world champion track cyclists. The bearings are sealed and feature Shimano's exceptional steel balls.The bearings are not adjustable.
