The PowerTap G3 hub has been redesigned to optimize stiffness and weight. Hub flange spacing was increased to improve lateral wheel stiffness, while weight was reduced by 90g to bring the G3 down to an impressive 325g. Internal hub electronics were moved outboard and are housed safely within the Power Dome cap to allow easier service and battery replacement.

The 2012 PowerTap PRO hub (430g) features a stealth black hub shell and a weight reduction of 52g compared to the previous PRO+ hub.

The HED Belgium C2 Clincher and HED Belgium C2 Tubular rims have the modern 23mm wide profile. The C2 series rims are growing in popularity due to their outstanding handling, acceleration, cornering and climbing performance.

HED named their C2 series rims after the lower coefficient of rolling resistance (Crr) and higher aerodynamics (Cda) provided by the 23mm wide rims. With 23c tires, the C2 rim creates a constant tire profile, rather than getting pinched into the rim. The overall ride quality is improved and the result is tubular-like ride quality from a clincher tire. The smooth transition from the tire to the edge of the rim allows laminar air flow and lower aerodynamic drag.

For riders wanting a slightly wider tire, we like the Vittoria Open Pave Evo CG clincher tire with the HED Belgium C2 clincher rim.
