Felt has launched the Nexar, an aero bike with an 800g claimed frame weight, which leads to a 6.48kg claimed overall weight for the top Dura-Ace spec. Felt also claims aerodynamics within 4 watts of the best-performing aero road bike. The brand says the Nexar is the lightest and fastest aero bike it has made. Its the successor to the AR, Felts original aero road bike, which was launched a full 18 years ago and last updated in 2020. Felt says the Nexar name denotes Next AR. It claims the Nexar is 5% faster than the previous-generation Felt AR and that its commissioned independent testing shows it to be within 4 watts of its (unnamed) fastest competitor at 40km/h. Felt has slimmed down the Nexar's frontal profile to reduce wind resistance. Felts analysis of the AR showed three areas where aerodynamics could be improved with the new frameset: the width of the head tube, the top tube/down tube interface and the wake behind the head tube. So Felt has reduced the frontal area by slimming down the Nexars frame tubes and hidden cables, bolts and other hardware. Its also updated critical areas of the frame to enhance stiffness, while adding compliance. That includes larger headset bearings, increased vibration absorption in the rear triangle and a beefed-up bottom bracket. Theres space to fit 32mm tyres. More comfortable geometry The Nexar's steeper seat tube is claimed to place the rider in a more efficient pedalling position. The Nexars geometry has been revised, so that the stack is a little higher and its reach slightly shorter than the AR. The seat tube angle has also been steepened and the seatpost has a zero offset, both placing the rider further over the pedals. Felt says the revised position helps the rider stay aero while still delivering power and increased stability. It reckons this benefits 99% of performance riders by making longer rides more comfortable. Felt is fitting shorter cranks to the Nexar across the size range. It has also gone with the trend of fitting shorter cranks, with lengths between 165mm and 170mm across the seven frame sizes to ensure consistent biometrics. The Nexar will be sold with two frame grades with different carbon specs. The Nexar FRD and Pro have the higher spec, with an 800g claimed frame weight around 300g lighter than the AR. All specs are fitted with a one-piece cockpit with a sub-300g claimed weight, in place of the ARs separate bar and stem. That leads to a claimed 6.48kg full-bike weight in the top FRD spec for a size-54 frame. Thats close to the 6.56kg of the 2026 Giant Propel Advanced SL 0 in size ML, which we reckon is the lightest aero bike weve seen. New owners The deeper head tube is engineered to reduce wake drag. Felt was established in 1991 in California by Jim Felt, who built its original tri bike before branching out into road, track and more, with its bikes ridden over the years by a cluster of star pros including Bradley Wiggins and Wout van Aert. Felt has gone through a number of owners including, at one time, the Rossignol ski brand. Since November 2025, Felt has been 100% owned by a duo of Spanish partners, and is now based in Barcelona, with a string of new performance drop-bar and tri bikes slated for launch this year and next, and distributed via a global dealer network. Felt Nexar specs The Felt Nexar will be sold in four Shimano specs: FRD with Dura-Ace, Pro with Ultegra Di2 and power meter, Expert with Ultegra Di2 without a power meter and Race with 105 Di2. Theres a framekit with frame, fork, cockpit and seatpost for the top FRD, too. Felt hasnt yet provided prices.
