THM CARBONES bottom bracket hybrid ceramic road road bike for BB30 frame
These cups are suitable for mounting the THM Clavicula to frames with bottom bracket housings according to the BB30 standard.
The standard is designed for the use of axle n with a diameter of 30 mm. The bearing distance of 68mm is relatively low, which would lead to high deformations of the axle . THM's solution has outboard bearings, so the axle less loaded, resulting in greater rigidity.
In addition, it offers the advantage of being able to use the same crank in frames with BB30 standard and those with BSA or Italian bearings. The complete system only gets slightly heavier.
Encapsulated for a higher rigidity and against the ingress of dirt through the seat tube.
THM uses stainless steel rings with ceramic balls treated by a special lubrication process. The main advantage is less extreme smoothness than longer life and less maintenance. However, due to the special properties of steel and ceramic, this combination is not suitable for high impact loads, therefore, these bearings are offered only for use on the road bike.
Suitable for all Clavicula versions!
