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.
← Bottom Brackets
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.
