The ENVE 4.5 SES Tubular Front Wheel (Chris King R45 Hub) Wheel is something to behold. An evolution of ENVE's patented SES rim shape, the 4.5's offer superb stability even in the most windy of conditions.

ENVE 4.5 SES Tubular Front Wheel (Chris King R45 Hub)

The ENVE 4.5 SES Tubular Front Chris King R45 Hub Wheel offers riders the pinacle in terms of carbon rim performance and stability. The Wheel is a dream for cyclists looking for performance and stability in an incredibly lightweight wheel.

ENVE's patented SES rim shape offers revolutionary all round stability and drag reduction and the 48 millimetre medium profile rim depth makes it ideal as an all round wheel.

Often a fear with carbon rims is a sub-par braking surface, however, this is not the case with the ENVE 4.5 SES Tubular Front rim as it has a wonderful moulded-in braking surface, which gives the brakes a better grip for increased stopping power. The braking surface also optimises heat management and modulation, so heavy braking doesn't damage the rim.

The 4.5 model also has the best lateral stiffness of any of the Smart ENVE System wheel models for the optimal path through the air and so you can transfer the highest amount of power through to the road.

With this new iteration ENVE have improved the rim's tubular tyre bed to optimise speed and minimise rolling resistance.

The Black Chris King R45 Hub offers riders possibly the best hub on the market in terms of overall performance and power transfer. The RingDrive™ Engagement Mechanism uses 72 engagement teeth on each drive ring. This means that the hub engages over three times faster than the standard 24 tooth pawl-type freehub. This allows you to transfer the maximum amount of torque into power, enabling you to go as fast as your legs will let you.

A sleek black finish with black decals ensure a timeless stylish look that will fit brilliantly with any frame.
