THM CARBONES bottom bracket Road for BB30 frames
These bearing shells are suitable for mounting the THM Clavicula on frames with BB30 standard bottom bracket shells.
The standard is designed for the use of axles with a diameter of 30 mm. The bearing distance of 68 mm is relatively small, which would lead to high deformations of the axle.THM's solution has external bearings, which means that the axle is subjected to less stress, resulting in greater rigidity.
It also offers the advantage that the same crank can be used in frames with BB30 standard and those with BSA or Italian bearings. The complete system is only slightly heavier.
Encapsulated for greater rigidity and to prevent dirt from penetrating through the seat tube.
Suitable for all Clavicula versions!
