From breakaways to the final sprint. On flat roads, climbs or descents. The reengineered Propel Advanced SL cuts through wind and maximises watts, optimising your energy through every dimension of speed: top-end speed, instant speed and sustained speed.

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 SL is quicker and more dynamic than ever. The whole system sheds 355g from the previous generation and is also more efficient with 14.2% more torsional stiffness and 14.8% greater pedalling stiffness—so you feel instantaneous reaction when you make your move.

Sustained Speed

Engineered for full-bike compliance, the new Propel Advanced SL delivers a significantly smoother ride when you’re rolling in the group or piling up training miles. The Vector integrated seatpost has 25% greater compliance compared to the previous generation. The fork and integrated cockpit absorb bumps and vibrations up front with 15% added compliance. And additional tyre clearance allows for high-volume tyres 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 tyres form a unified system that lowers total resistance when you’re pushing high speeds in the wind—whether you’re on a solo break, taking pulls at the front, or powering away on a climb. The AeroSystem frame and integrated cockpit minimise drag, while the new CADEX Max 50 WheelSystem and Aero tyres reduce rolling resistance. Calculating linear aero drag, wheel rotating drag and tyre rolling resistance, it all adds up to a total energy savings of 18.4 watts.
