These custom, Swiss made bearings are double sealed which gives much greater life span than stock units. They are designed to run directly on the crankset axle, without the use of shims or spacers to increase life and reliability. A non-contact, free running labyrinth seal protects the bearing externally, and the machined aluminium center tube is sealed internally with o-rings.
Suitable for 68 and 73mm widths
Internal and external sealing
Compatible with Shimano, Race Face and Truvativ (Truvativ requires extra adapters)
