BSA framesets

BSA frames are very popular frames and this old standard of the 2000's is coming back in the 2020's with Specialized bikes. The thread allows perfectly aligned bearings which means durability and smoothness. Famous bikes with BSA are Tarmac SL7 and SL8. We supply bearings for these bikes in order to assemble Shimano, Sram and Rotor cranks: 24mm, 30mm, GXP and DUB.
