Gavia SL Carbon Road Bike

Size Guide


The limit defying Gavia SL was built to push riders to that next level of speed and performance.  The Gavia Pass is known for being the highest and most grueling mountain pass in the Italian Alps, and you have to be on top of your game to tackle this kind of challenge.  With this level of performance and perfection, we held nothing back on the Gavia SL.  From the SuperLight Toray T800 carbon frame to the full Ultegra 6800 groupset, the Gavia SL was built to perform at the highest level and help riders reach their goals.  Like every bike on, the Gavia SL comes with our signature Ready To Ride Build service.




Super Light Toray T800 carbon frame and fork make up our stiffest most powerful frame ever, for explosive power on demand.



A full Ultegra 6800 drivetrain offers precision shifting, incredible control, and weight savings.  This 52/36T crankset and 11-25T cassette were built for speed, and you will feel the power with every pedal stroke.



The Tommaso Corsa TC-50C Carbon Wheels are 1520 grams of pure performance and power.  Lightning quick acceleration and unprecedented aerodynamics are your ticket to the top.
