THM Carbones bearing for BB30 frame 99g
These bearings are suitable for the installation of the THM Clavicula on frames with bottom bracket shells after the BB30 standard.
The standard is the use of axle adapted n having a diameter of 30mm. The bearing spacing of 73 mm is relatively low, leading to high deformations of the axle would lead. THM's solution has externally adjusted bearings, thus being axle less stressed, which is reflected by a higher rigidity.
It also offers the advantage that you can use the same crank in frame with BB30 standard and those with BSA or Italian stock. The entire system is only slightly heavier.
Encapsulated for greater rigidity and against the penetration of dirt through the saddle tube.
Suitable for all versions clavicle!
