ETERNA LV Fluid
Bearings
Where SUPRA LV targets pure pulley performance, ETERNA LV is chosen for ceramic bottom bracket bearings, which carry load as well as speed.

Thread Bottom Brackets
Threaded bottom brackets for BSA, ITA and the T47 family. The 3-in-1 Core System takes Shimano 24 mm, SRAM DUB 28.99 mm and Rotor 30 mm spindles, so a crank change does not mean a new bottom bracket.

Bottom bracket fitment
