XD50 and XD51 is a range of hub with flange for straight-pull spokes for MTB world. Available in the Center Lock version or with 6 bolts. The keystone defining the assets of the XD50/XD51 can be found in the precision in its construction. The tolerance limits are reduced to the micron, thanks to the use of cutting-edge numerical control machines, as well as the meticulous verification of each individual dimension. The new flange has been designed with a particular bridge configuration thanks to which it is possible to counterbalance the braking force, thus increasing its reliability and durability. The XD50/XD51 seals make these hubs more resistant to atmospheric agents and natural wear and tear, which could affect their smoothness over time. The components require very little ordinary maintenance, while at the same time maintaining their performance constant over time.XD50 / XD51 HUBS
