General Information

ROAD BIKE WHEELS HIGH PERFORMANCE
If you are a lover of the tubular and want to have the maximum aerodynamics, without giving up safety in case of wind, the MIURA TR67 are the wheels made for you. Like the entire TR family, this rim has been designed following the aerodynamics of the NACA 0027 profile which allows cyclists who love mixed routes to be able to pedal at maximum performance.
The 28mm channel ensures a perfect coupling with 25 and 28mm tubulars and enhances the shape of the most generous covers allowing you to create the continuous profile with the rim. The carbon used is impregnated with a particular resin that is very resistant to the high temperatures reached during braking by the cyclist. To complete the set-up, and to ensure that the rim can express itself at its best, you’ll have 24 straight-head spokes and the Ursus RD40 aluminum hubs machined by the CNC with highly smooth ball bearings. The choice of using Sapim CX-Sprint spokes allows the traction forces to be divided equally and more evenly during the most violent sprint and braking. Also available in the caliper brake version (see TR67).

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.
