Introducing the new Propel Advanced SL Disc RED
Launch your attack. Sprint for the win. This composite aero rocketship combines AeroSystem Shaping Technology with the all-new SRAM RED eTap AXS wireless electronic groupset. The result: efficiency, control, and race-winning speed.
AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimizes aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SLR Aero cockpit help produce the best overall aero performance.
A SRAM RED eTap AXS electronic wireless drivetrain gives you a wider gear range with quick, precise shifting so you’re always in the right gear. Integrated hydraulic disc brakes deliver smooth braking power and modulation, and an integrated WheelSystem with a 65mm rear rim and 42mm front rim optimizes aerodynamics and control.
The SRAM RED eTap AXS drivetrain includes an integrated Quarq DZero power meter to provide precise training and racing power data. The wireless electronic shifting system features new derailleur technologies and simple, intuitive shifter/brake levers.
