THM CARBONES bottom bracket MTB for PressFit 30 frame
These cups are suitable for mounting the THM clavicle on frames with bottom bracket housings according to the PressFit 30 standard.
The standard is designed for the use of axle n with a diameter of 30 mm. The bearing distance of 68mm / 73mm 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-PressFit 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.
Suitable for all Clavicula versions!
