URSUS rear hub RD50 Straightpull Center Lock 12×142 mm | Freehub SRAM XDR

Ursus is an Italian bicycle company based in Rosà, a small town in northern Italy. With almost 50 years of experience in development and manufacturing, they have built up a comprehensive portfolio of bicycle components. All components are developed in-house, manufactured and tested on modern CNC machines, which ensures consistently high quality.

The Ursus XD51 is the right choice for anyone looking for a comparatively light and stiff hub. This is achieved through the use of aluminum 7075 and a 15mm axle . By choosing large bearings with a good LLU/LLB seal and an additional splash guard in front of the bearings, a long service life with minimal maintenance is achieved.
