Ursus has debuted two new hubs called the RD50 and RD30 aimed at catering to the all-consuming rise of disc brake systems in the road bike segment.
RD50
The RD50 features a new hub flange that’s designed to work with straight-pull spokes, along with an aluminum 7075 body, while tolerances have been reduced to the micron thanks to the use of cutting-edge numerically controlled machines.
“The keystone defining the assets of the RD50 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. RD50 supports the action of your legs, giving you the feeling of greater explosiveness on the pedals. This happens thanks to the radius angle of the body, which is reduced compared to the previous range of hubs,” says Ursus
Additionally, Ursus has also reduced friction courtesy of new pressure seals that ensure a higher level of protection for the hub’s SKF bearings.
“Water, mud and dust have always been enemies of bike components, but the new RD50 seals make these hubs more resistant to atmospheric agents and natural wear and tear, which could affect their smoothness over time. In short, we are talking about components that require very little ordinary maintenance, while at the same time maintaining their performance constant over time,” says the Italian brand.
RD30 hubs:
Like it’s predecessor, the RD30 hub shares the same technical imprint, but with the inclusion of new flanges that are designed to work with J-bend spokes. The hub also gets a new glossy anodized finish.
Both the RD50 and RD30 are compatible with Shimano, SRAM and Campagnolo free-hub bodies
