Exceptional Handling. Ultra Lightweight. Ready to Conquer Any Peak.

Introducing the new Princeton CarbonWorks Peak 4550 Carbon Disc Brake Wheelset, a lighter, stiffer, stronger, and more aerodynamic design directly targeted at world tour and grand tour racing.

Development priorities were to create an all-around race-ready wheel with exceptional aerodynamic characteristics and the strength and stiffness to transfer high wattages to the ground.

The performance characteristics of grand tour riding are extremely difficult to synthesize in a single wheelset. Riders need wheels that are light and responsive for the climbs, but on the descents, they need predictable and sharp handling. In the valleys, the wheels need to be aerodynamic and impervious to crosswinds. And above all of that, the wheels need to hold up to thousands of miles of full gas racing.

Princton Carbonworks standard non-drilled tire bed facilitates a stiffer outer rim and transfers some material away from the tire bed to other critical areas in the wheel, helping to keep wheel weight low while maintaining high stiffness values.

Note: These wheels are also offered with Carbon Ti, TUNE, White Industries, DT Swiss 180EXP, or Chris King R45D Ceramic. Please reach out to customer service at 1(800) 682-0570 to find availability. We can special order custom wheels with extra lead time. Prices may vary depending on the hub selected in the event of a special order.
