Highlights

Instant Speed

In the moments when explosive speed matters most—launching an attack, chasing a break, or sprinting for the finish line—the new Propel Advanced Pro is quicker and more dynamic than ever. The frameset is lighter than the previous generation with greater torsional stiffness and pedaling stiffness—so you feel instantaneous reaction when you make your move.

 

Sustained Speed

A reengineered frameset and integrated components combine for a smoother ride when you’re rolling in the group or piling up training miles. The Vector seatpost offers greater compliance compared to the previous generation, while the fork and integrated cockpit absorb bumps and vibrations up front. And additional tire clearance allows for high-volume tires up to 32mm, further smoothing out the ride to help you maintain higher speeds with less fatigue.

 

Top-End Speed

The frameset, cockpit, wheels and tires form a unified system that lowers total resistance when you’re pushing high speeds. The AeroSystem frame and integrated cockpit minimize drag, while the aero WheelSystem and tires reduce rolling resistance. That means more speed for taking pulls, rolling off the front, or driving the pace across flats and over climbs.
