THM Carbones bearing for BB30 frame 99g
These bearings are suitable for the installation of the THM Clavicula on frames with oversize bottom after the BB30 standard.
The standard is designed for the use of axes with a diameter of 30mm. The bearing spacing of 68mm is relatively low, which would lead to high deformations of the axle. THM's solution has externally seated bearings, thus the axle is less stressed, which is reflected by a higher rigidity.
Moreover, it provides the advantage that one can use the same crank in frames with BB30 standard and ttube with BSA or Italian stock. The complete system is only slightly heavier.
Encapsulated for greater rigidity and against the ingress of dirt through the seat tube.
Suitable for all versions clavicle!
Material: aluminum, steel
