The RT-1100 is constructed with our premium KSL Superlight Carbon using polyurethane molds to optimize compaction, reducing weight and increase frame stiffness. Shimano's Ultegra drivetrain and hydraulic disc brakes offer premium performance and consistent braking in any weather and at any speed. The endurance geometry is further complimented by shaped seat stays providing increased compliance for more comfort over uneven road surfaces
Disc brakes provide confidence inspiring stopping in all weather conditions
Taller headtubs, slacker head and seat angles and longer wheelbase provide optimized rider control and comfort.
Fast in the wind, the RT-1100 is optimized to slice through the wind
