THM Carbones Clavicula MTB M3 LK 104 | 64. Tune chainrings
THMs super light and stiff crank for the mountain. It has a spider for the installation of 2 chainrings with the standard 4-arm bolt circle diameter of 104 | 64 mm.
The Spider is based on the concept of the Sram XX-Spiders with LK 120 | 80. It will be this chainrings required which have a thread in the large chainring.
The M³, unlike its predecessors, an axle made of aluminum rather than carbon, the well-known, high stiffness is however not affected. As with THM usual, there are suitable internal storage for nearly all common bottom bracket systems. The spider can easily against another (eg 2-LK 120 | 64 | 80 or 3 times 104) are exchanged.
THM provides to its cranks to different bearing for the most common bottom bracket standards.
All internal bearings feature high-quality, double sealed ball bearings. For installation, a
THM tool needed, which is available in our shop.
