Use stack before the size label
A 54 FR, AR and VR can all match the same rider height. The VR puts the bars higher, while the FR and AR ask for more flexibility or spacer adjustment.
Felt Bike Size Chart
Size chart and fit 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.

Fit decision guide
How to choose the right Felt size
Felt uses numeric sizes across road and gravel, but the ride position changes a lot by model. The chart gets you close. After that, compare FR, AR, VR, Breed and IA by front-end height, reach and how much cockpit adjustment the frame allows.
Best first check
Pick the height and inseam row first, then compare stack and reach on the model you actually plan to buy.
Race vs endurance
FR and AR feel lower at the front than VR. A rider can fit the same number on all three and still feel very different on the bike.
Triathlon check
IA sizing depends on pad stack, pad reach and saddle position. Treat the road chart as a starting point, not a final answer.
What to check after height and inseam
Leave room for the cockpit
Felt aero front ends do not offer endless stem and spacer swaps. If your reach is already long on the smaller size, sizing up usually makes the problem harder to fix.
Model family fit notes
FR and AR
Road BikeBest for: racers who want a lower front end and a sharper road position
Most riders can start with their normal numeric road size, then check whether the reach feels too long once the aero cockpit is included.
Fit tip: If you are between two numbers and want crit-style handling, the smaller size is usually easier to tune.
VR
Road BikeBest for: long rides, endurance events and riders who want less bar drop
The VR fits the same height ranges as the faster road frames but gives more stack. It is the safer pick when comfort matters more than a low race position.
Breed
Gravel BikeBest for: gravel riders who want standover and stable handling on loose surfaces
Breed sizing tracks Felt road numbers but gives more off-road clearance. Riders coming from a Felt road frame usually start with the same numeric size.
Fit tip: Size down only if you want extra standover for technical descents.
IA
Best for: triathletes and time-trial riders checking pad position
IA fit depends on pad stack, pad reach, saddle setback and arm-pad width. Match those numbers before using the road size chart as a buying guide.
If two Felt sizes look possible
Choose by the position you can hold for the whole ride, not by the bigger number. Felt's aero and triathlon frames reward a frame that is close before stem, spacer or pad changes.
- Pick the smaller FR or AR if you want a lower, racier cockpit and can handle the drop.
- Pick the larger VR if you want a calmer endurance position and a bit more front-end height.
- Do not buy an IA from height alone. Match pad stack and pad reach first.
Popular Felt Models & Sizing Notes
Specific sizing recommendations for Felt's most popular bike models. Geometry measurements shown for reference size (typically M or 54cm).
Felt FR Advanced
🚴 Road Bike • 2025Pure 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.
Stack: 535mmReach: 390mm
Felt AR Advanced
🚴 Road Bike • 2025Previous-generation aero road platform - Felt replaced the AR with the NEXAR, so new AR stock is clearance only. 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.
Stack: 545mmReach: 385mm
Felt VR Advanced
🚴 Road Bike • 2025Endurance 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.
Stack: 575mmReach: 375mm
Felt Breed
🏔️ Gravel Bike • 2025Adventure 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.
Stack: 570mmReach: 380mm
Felt Broam 60
🏔️ Gravel Bike • 2025All-road adventure gravel bike with relaxed endurance geometry - taller stack and slacker head angle than the Breed for big-mileage gravel and light bikepacking. Clearance for 700x45c (or 650b x 50c). Size 56 sits at 605 mm stack / 385 mm reach, around 35 mm taller in stack than the Breed at the same numeric size, so cross-shoppers between the two should compare stack rather than the size number. Felt recommends the same numeric size as the Breed; riders between sizes who prioritise comfort over reach should pick the larger frame.
Stack: 605mmReach: 385mm
Felt IA 2.0
🚴 Road Bike • 2026Triathlon frame (also searched as 'Felt TT bike') built around integrated hydration and storage. The current IA 2.0 is designed for triathlon rather than UCI time-trial rules, so fit adjustability matters more than the frame label: size on your functional threshold position and get a professional fit before buying. The listed 510 mm stack / 410 mm reach reflect a size 56 in the IA platform, with reach deliberately longer than a road frame because the saddle sits further forward over the bottom bracket.
Stack: 510mmReach: 410mm
Felt Sizing Tips
How to Measure
- • Height: Stand barefoot against a wall and measure from floor to top of head
- • Inseam: Stand barefoot with feet 6 inches apart, press a level book firmly upward, and measure from the floor to its top edge
- • Arm Reach: For road bikes, measure from shoulder to fingertips
When Between Sizes
- • Comfort priority: Choose the larger size
- • Performance priority: Choose the smaller size
- • Long torso: Size up for better reach
- • Long legs: Size down for better standover
