Highlights
225g Weight Savings
The reengineered Advanced SL frameset sheds 225 grams over the previous Propel without giving up stiffness. That is real, felt weight loss the moment the road tilts up.
AeroSystem Shaping
Truncated airfoil tubes shaped in the wind tunnel keep you fast whether the wind is dead ahead or gusting from the side. Speed you hold with less work.
Internal Cable Routing
Cables and hoses run hidden through the handlebar and frame for a clean cockpit and easy fit changes. Dialing in your position is straightforward when it comes time to set it up.
OverDrive Aero Steerer
The full-composite steerer gives the finished bike a stiff, accurate front end for high-speed handling. Commit to a line and it stays put.
32mm Tire Clearance
Room for tires up to 32mm means you can run wider rubber for grip and comfort on rougher Valley roads. A race frame that is not locked to skinny tires.
