This well-loved Allez Sprint came to us with a mix of tired components that needed replacement. Working with the customer, we decided to start fresh and strip the bike down to a bare frame and rebuild.

Whether it's specific fit requirements, unique component requests, or a desire to ride something different, a frame-up custom build is for you! We had the pleasure of building up this gorgeous S-Works Tarmac SL8 with lower gearing and a more adjustable two-piece cockpit. Crux, Aethos 2, Tarmac SL8, and Allez Sprint frames are available!
