Product details
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 pedalling 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 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. The AeroSystem frame and integrated cockpit minimise drag, while the aero WheelSystem and tyres reduce rolling resistance. That means more speed for taking pulls, rolling off the front, or driving the pace across flats and over climbs.
Highlights
With a new frameset that’s now lighter and more efficient—delivering greater torsional and pedaling stiffness for precise handling and improved power transfer—the next-generation Propel Advanced Pro blends straight-ahead speed with an improved overall ride quality. The Vector composite seatpost and integrated cockpit offer more compliance, absorbing bumps and vibrations at both ends of the bike to help minimise fatigue so you can sustain higher speeds. The WheelSystem features 50mm deep composite rims paired with CADEX Aero tyres to reduce wind drag and rolling resistance. Even the bottle cages are designed for speed, made specifically for the frame to help optimise airflow.

WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
