Propel Advanced Pro Frameset

Now even faster, this aero rocketship is built for speed when it matters most. The reengineered frameset is even more adept at slicing through wind, and it's also lighter than the previous generation. The result? Race-winning efficiency that's hard to beat.

Key Performance Factors Integrated aerodynamics 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/SL Aero cockpit produce the best overall aero performance. Easier adjustability All-new cable routing through the handlebar and frame makes it quicker and easier to adjust or change cockpit components and fine-tune performance and riding position.

Race-winning efficiency Advanced-grade composite frameset features high-performance materials and proprietary manufacturing processes. As a result, it's now lighter than the previous generation for an improved stiffness-to-weight ratio.
