Rolf Prima Ares3 Carbon Clincher Road WheelsetDo you feel the need for speed? Good. Rolf Prima's wheels are purpose-built for speed. It doesn't matter if you're climbing, descending, or negotiating a sweeping bend, as this Ares3 Carbon Clincher Road Wheelset is ready and willing to carry you with their aero edge Carbon ClimberThis wheelset may be the weapon of choice when you're trying to emulate Chris Froome or Nairo Quintana on the climbs but that doesn't mean you have to pay a comfort penalty. Constructed for climbers, it's no surprise that this wheelset is extremely light. The front wheel weighs in at an impressive 580g with the rear wheel at 760g. Weight savings are possible through Rolf Prima's Paired Spoke Technology. The engineering neutralises pulling forces to offer a lighter and smoother roll. In turn, you receive a huge boost in aerodynamic performance.A TdF5.5 Hubset comes with Enduro ceramic bearings to save further weight; Rolf Prima claims this has a 20% gain in lateral stiffness to produce the perfect climbing combination. The front and rear wheels have sixteen spokes that also offer aerodynamic advantages.

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.
