The new hub R40 come with an unique design, conceived to mount exclusively straight-head spokes. It ensures maximum wheels rigidity and allows a perfect alignment of spokes and rim holes. A precise design was studied to allow the spokes to fit perfectly with the hub flange. In addition to this the head of the spokes are completely integrated.

You will fully understand the aesthetic beauty of these hubs as soon as you touch their surface. We invented the new VelvetTouch finish; the body of the hub is manufactured with a special process that creates the effect of velvet. The black anodizing at the end of the production process enhances the contrast between the opaque of the hub body and the shiny of the flange grooves, obtaining an exclusive Ursus finish.
