BB30 Bearings MTB

PRODUCT OVERVIEW

These bearing cups are suited for installation of the THM Clavicula on frames with bottom bracket housings to BB30 standard applicable to axles with 30 mm diameter. The bottom bracket housing is 68 mm wide and its inner diameter is 42 mm. The snap rings wich for the BB30 standard are used as limit stop when pressing in the bearings, must not be installed. The relatively small bearing clearance of 68 mm could lead to considerable axle deformations. Our solution with bearings at the outside involves a reduced load on the axle which can be seen from the higher rigidity. Another advantage is the facility of using the same crank for frames to BB30 standard and those with BSA or Italian thread. The increase in weight of the complete system is neglegible.

To install this bottom bracket, the THM socket wrench is needed.
