Find your size
The NEXAR is an aero bike made for 99% of riders. A higher stack and a shorter reach keep you fast and comfortable on long rides. We developed it with 3 professional bike fitters, engineering all 7 sizes from scratch, so getting your size right is where all day aero starts.
Three body measurements are all you need. Enter them below to see the NEXAR frame size that fits you, why it fits, and the handlebar and crank that come with it. Use it as your starting point, then confirm the final fit with an authorized FELT dealer.
Measure
Take three measurements at home: height, inseam and shoulder width.

Take these three measurements barefoot. Ask a friend to help for accuracy.
Height
Stand against a wall with your heels together and look straight ahead. Measure from the floor to the top of your head.
Inseam
Stand with your back to the wall and your feet about 15 cm apart. Press a book up between your legs the way a saddle would sit. Measure from the floor to the top of the book.
Shoulder width
Measure the distance between the bony points on top of your shoulders. This guides your handlebar width.
Enter your measurements
Height sets the frame size, inseam checks standover clearance, and shoulder width guides the handlebar width.
Every letter on the NEXAR geometry chart is a measurement that shapes how the bike fits and handles. Hover or tap any letter to see what it means. Dimensions are drawn to the size M geometry.
Every size is developed as a standalone geometry. The rider height row is FELT's guidance for each size. Use it together with the size finder above.
The NEXAR comes with the FELT one piece integrated carbon cockpit, the lightest FELT has ever built. Full cable integration runs through the headset for a cleaner, faster and stiffer front end.
- Weight. 289 g, 297 g and 314 g depending on size, against 505 g for the previous two piece cockpit.
- Sizing. A handlebar size is matched to every frame size, so your proportions are right across the full range.
- Fine tuning. The aftermarket range extends the stem length up to 120 mm and adds a fourth size, so a fitter can dial your position to the millimetre.
The frame sets your position. A professional fitter fine tunes the rest from rider to rider: saddle height, saddle position, cleat position, handlebar height, and the handlebar width measured against your shoulders. FELT keeps a range of cockpit sizes in stock, so the fitter can match your proportions.
The best way to understand your fit is to ride it. Selected FELT dealers let you test the NEXAR before you buy. In 2026 the Test Demo Program is available in the USA and Canada only.
