Official sizing guide for 2026
Felt's sizing draws on their deep roots in triathlon and time trial engineering, where millimeters of fit adjustment directly impact performance and aerodynamics. Their frames use numeric sizing increments to provide granular options, and each size receives dedicated aerodynamic profiling rather than uniform tube shapes. Felt's Bayonet fork system and integrated cockpit designs mean correct frame sizing is critical, as stem and spacer adjustability is intentionally limited to preserve aerodynamic integrity.
| Size | Height Range | Inseam Range |

Specific sizing recommendations for Felt's most popular bike models. Geometry measurements shown for reference size (typically M or 54cm).
Pure race road bike built around Felt's TeXtreme carbon platform. Features the Bayonet fork with integrated headset—limited stem adjustability means precise frame sizing is essential. Riders focused on criterium racing may prefer sizing down for sharper handling.
Aero road bike with truncated airfoil tube profiles validated in Felt's own wind tunnel. Slightly more relaxed than the FR with a taller head tube; riders coming from traditional road bikes generally fit true to their standard numeric size.
Endurance road bike with a compliance-tuned seatpost and taller head tube for all-day comfort. More upright geometry than the FR or AR—riders between sizes should choose the larger frame for a more comfortable, less aggressive position.
Adventure gravel bike designed for mixed-surface versatility with clearance for 700x45mm tires. Slacker head angle and longer chainstays than the VR provide off-road stability—sizing runs similar to Felt road bikes but with added standover height.
Triathlon and time trial platform with a UCI-legal frame and integrated hydration storage. Sizing is based on rider's functional threshold position rather than traditional road measurements—a professional bike fit is strongly recommended before purchasing.
