Finding your size on a Felt road bike
Felt splits its road range into three clear jobs: the FR is the lightweight race climber, the NEXAR is the aero bike (it replaced the older AR in 2026), and the VR is the relaxed endurance model. The most useful thing to know is that these three fit very differently at the same numeric size. A 54 in the VR sits far taller and shorter at the bars than a 54 in the FR, so pick the model that matches your riding first, then size within it. You can see what is in stock in the Felt collection.
Please note. These charts are indicative, not a guarantee. Height alone does not decide fit; proportion, flexibility and riding style all play a part, and two riders of the same height can need different sizes. Use this as a starting point and confirm against the exact bike before buying.
Quick size finder
| Rider height | Leg length (inseam) | FR (race) | NEXAR (aero) | VR (endurance) |
|---|---|---|---|---|
| 148–158 cm | 68–74 cm | 45 | 45 | 43 / 47 |
| 158–168 cm | 73–78 cm | 48 | 48 | 47 |
| 168–173 cm | 77–82 cm | 51 | 51 | 51 |
| 173–178 cm | 80–85 cm | 54 | 54 | 54 |
| 178–183 cm | 83–88 cm | 56 | 56 | 56 |
| 183–188 cm | 86–91 cm | 58 | 58 | 58 |
| 188–196 cm | 89–95 cm | 61 | 61 | 61 |
Felt publishes broad, overlapping height bands, especially around the 47 and 48 sizes. If you sit near a boundary, use your inseam and preferred position to break the tie.
How to measure yourself
Height. Stand against a wall without shoes, heels together, and mark the top of your head. Measure straight down to the floor.
Leg length (inseam). With your back to the wall, place a hardback book spine up between your legs and pull it firmly against your body, as a saddle would sit. Mark the top edge on the wall and measure down to the floor. Inseam is the strongest single guide to standover and saddle height.
FR (race climber)
The lightest and sharpest handling frame in the range. Racy without being extreme, with a moderately low front end and a short reach that keeps the bike lively.
| Size | Stack (mm) | Reach (mm) | Rider height |
|---|---|---|---|
| 45 | 496 | 365 | 145–152 cm |
| 48 | 509 | 371 | 152–160 cm |
| 51 | 527 | 375 | 168–173 cm |
| 54 | 546 | 385 | 173–178 cm |
| 56 | 567 | 390 | 178–183 cm |
| 58 | 590 | 404 | 183–188 cm |
| 61 | 617 | 412 | 188–196 cm |
Fit character: a lively, precise race climber; aggressive at the front but holdable for most fit riders.
NEXAR (aero)
The current aero bike, and deliberately friendlier than the AR it replaced. It carries a taller stack and shorter reach, so the aero position is one most riders can actually hold. Cockpit width and crank length change with size, so the fit arrives dialled from the factory.
| Size | Stack (mm) | Reach (mm) | Rider height |
|---|---|---|---|
| 45 | 504 | 355 | 145–152 cm |
| 48 | 522 | 365 | 152–160 cm |
| 51 | 537 | 370 | 168–173 cm |
| 54 | 558 | 380 | 173–178 cm |
| 56 | 576 | 390 | 178–183 cm |
| 58 | 600 | 395 | 183–188 cm |
| 61 | 631 | 405 | 188–196 cm |
Fit character: accessible aero, a fast position that most riders can sustain all day.
VR (endurance)
The comfort choice, with the tallest stack and shortest reach of the three and clearance for wide tyres. The front end sits noticeably higher, so the same number feels much more upright than on the FR or NEXAR.
| Size | Stack (mm) | Reach (mm) | Rider height |
|---|---|---|---|
| 43 | 521 | 355 | 145–152 cm |
| 47 | 539 | 362 | 152–160 cm |
| 51 | 555 | 369 | 168–173 cm |
| 54 | 576 | 379 | 173–178 cm |
| 56 | 595 | 386 | 178–183 cm |
| 58 | 614 | 392 | 183–188 cm |
| 61 | 633 | 401 | 188–196 cm |
Fit character: relaxed and stable, the easy all day pick with room for big tyres.
A note on the AR
If you are looking at an older Felt AR, it was the aero race bike before the NEXAR. Its fit is more aggressive, with a longer reach and a lower stack, and geometry varies by model year. Confirm the stack and reach of the specific frame year against your target position rather than assuming it matches the NEXAR.
What Felt riders find
Reviewers describe the FR as stiff, quick and rewarding, with a front end that is aggressive but sustainable for most fit riders. The NEXAR earns praise as an aero bike built for real riders rather than only racers, thanks to its higher stack and size specific cockpit. The VR is the clear comfort pick: compliant, stable and happy on rough roads, with the most upright position of the range.
Between two sizes?
When your height sits between two rows, let intent decide. Size down for a lower, racier position and sharper handling; size up for more comfort and stability. On the VR most riders lean towards the larger size, while on the FR a size down suits crit style handling. Share your inseam and current fit and we will help you choose.

Stack and reach figures are official where available. NEXAR values come from a full manufacturer sourced table; FR and VR values come from published Felt geometry for the matching size range and may shift a few millimetres on the newest frame revisions. Felt height bands are broad and overlapping, so treat the smallest sizes as approximate. Always confirm the geometry of the exact bike before you buy.
