The FR2 Disc is crafted from Felt’s UHC Advanced + TeXtreme carbon fiber for a high stiffness-to-weight ratio that maximizes rider performance by ensuring that no watt is wasted. Every tube has been optimized in size and shape to maximize speed and minimize weight. Matched with Felt's tapered carbon fork and hydraulic disc brakes, the FR2 Disc delivers an incredibly balanced feel no matter what the weather brings. Gear changes come easily with Shimano's Ultegra Di2 electronic drivetrain, while Mavic Ksyrium Elite wheels wrapped in racy Mavic 25c tires provide great sprinting acceleration. The rest of the FR2 Disc is built with components carefully chosen to maximize speed and efficiency, including 3T's feathery handlebar, stem, and seatpost. The complete bike includes carbon assembly paste, chain plate protector, Di2 internal battery charging cables, and a 7075-AL CNC aluminum seatpost clamp with titanium 5mm bolt.
