CARRIAGE: Add item to Basket to show carriage costs (you can easily remove it)
- This BB-Set is made for two-piece cranks where the drive side crank is attached to the axle. The benefit of H-Type BB is that the bearings are positioned externally meaning they can be larger meaning that the load capacities of the ball bearings could be increased. This contributes to the stability of the entire system and to its longevity. The housings are manufactured by CNC from high strength 7075-T6 aluminium in order to ensure a perfect frame/BB interface. To guarantee the longevity of our BB sets the manufacturing process is supervised precisely and in great detail. The BB Pro and S-Pro are delivered with a 2.5 mm spacer enabling compatibility with 68 mm and 73 mm width shells. Of course both chain guides as well as E-type front derailleurs can be installed. For more information on installation and usage, please consult the product instructions.
