FeaturesFIT Woman FIT Woman products are specifically designed and engineered for women cyclists.  All Felt FIT Woman products include a detailed combination of women’s design-specific geometry, tube length, frame material lay-up, anatomical component selection and more.

Inside Out InsideOut is a revolutionary internally optimized molding process that completely eliminates excess material, and therefore weight, inside the frame tubes and junctions.  Placing polyurethane inserts inside the frame during the molding process—especially at the bottom bracket and head tube area—and then applying  a precise amount of pressure and heat results in perfectly formed tubes, inside and out.

Modular Monocoque Modular Monocoque Construction (MMC) is an advanced carbon fiber manufacturing technique that allows Felt to mold individual sections of the frameset and then join them together.  The main advantage of MMC is that it allows each section to be optimized to meet the specific engineering demands of that particular section of the frame.

VR Stay Vibration reducing carbon fiber seatstays designed to dampen road and trail vibration, creating a smoother rider quality, improving control and reducing overall fatigue.

UHC Performance UHC Performance is a T700- based blend of raw carbon fiber, which has a tensile strength that’s 7.9 times greater than 3/2/5 titanium and a stiffness rating that’s 3.34 times greater than 6061 aluminum.  UHC performance brings the unmatched performance of a Felt carbon fiber bike to more affordable pricing levels than ever before.
