Leave the peloton trailing in your wake with the Rolf Prima Ares4 Disc Front Road Wheel, certain to hand you an aerodynamic boost over your rivals.
|Front Axle Type:||Unknown|
|Wheel Size:||700c (622)|
The perfect allrounder ready to accelerate you along the road. The Ares4 loves climbing and downhill sections while attacking corners at full pace doesn’t mean you have to compromise on grip.
Perfect for those who love mountain stages, this lightweight front road wheel combines spoke and Delta Rim technology to offer a smoother roll with increased stability. With the XST+ Hubset manufactured with zero ceramic bearings, the additional weight savings help increase your pace while the high-end braking ability ensures for a safe passage during your ride.
Paired Spoke Technology: Rolf Prima's Paired Spoke technology broke new ground when it was introduced in 1997. Bringing the spokes to the rim in pairs neutralises the left and right outward pulling forces, which allows them to build true wheels on lighter rims with fewer spokes. Fewer spokes and lighter rims help create increased aerodynamics and faster performing wheels.
Differential Flange Diameter™: Rolf Prima's patented oversize non-drive Differential Flange provides the leverage to transmit drive torque in the rear wheel to the non-drive spokes, thereby increasing the number of torque absorbing spokes.
Delta Rim Technology™: In skydiving, the Delta track is the fastest position for gaining forward airspeed. So, Rolf Prima mirrored this observation and adapted it for their Delta profile, which takes that cue using increased width and sidewall shaping to improve airflow and stability in straight on and crosswind situations. This wider rim is not just faster, but the additional tyre support improves cornering and handling in all riding conditions.
