The name says it: NEXAR is the \"Next-AR,\" the direct successor to Felt's pioneering AR platform that built the brand's reputation in aerodynamics over 35 years of CFD modeling, wind tunnel testing, and carbon engineering. The stated goal was to build the fastest road bike Felt had ever made — and to make it work for a broader range of riders than aero bikes typically accommodate.\u003c\/p\u003e\n\u003cp\u003eThat goal shapes everything about the NEXAR's design philosophy. Rather than maximizing aerodynamics at the expense of weight or fit, Felt built the platform around three deliberately balanced pillars: aero, weight, and fit. The NEXAR delivers a 5% drag reduction over the previous AR model and sits within 4 watts of the fastest full-aero bikes on the market at 40km\/h. The FRD-spec frame weighs 800g — which Felt states is the lightest in the full-aero category. And the geometry has been rethought from the ground up to support real performance riders in real-world conditions.\u003c\/p\u003e\n\u003cp\u003eThat geometry story is worth understanding. Where traditional aero bikes often force riders into aggressive positions that erode power and comfort over the course of a long effort, the NEXAR adopts a slightly higher stack and shorter reach across all seven sizes, with crank lengths matched to frame size — 165mm through 170mm — to support equal biomechanics at every position. The geometry is precise enough that a straight-column Felt NEXAR Carbon seatpost works across the full size range without an offset. For riders who've been skeptical of aero bikes because of fit compromises, this is the answer to that objection.\u003c\/p\u003e\n\u003cp\u003eThe NEXAR Pro uses Felt's FRD 12k carbon construction throughout — the same advanced carbon specification used across the NEXAR line — delivering the stiffness-to-weight ratio and aerodynamic efficiency the frame is designed around. The drivetrain is Shimano Ultegra Di2 from end to end: R8150 electronic front and rear derailleurs, R8170 hydraulic disc brake\/shift levers, and R8170 hydraulic calipers biting on Shimano MT900 140mm rotors. The crankset is a Shimano Ultegra R8100 with a 4iiii non-drive side power meter already installed — meaning you roll out with training data from your first pedal stroke, no additional investment required. A 52\/36 front ring pairs with an 11-30 12-speed cassette.\u003c\/p\u003e\n\u003cp\u003eWheels are Vision Metron 45 SL Carbon front and rear — a 45mm deep carbon clincher that delivers meaningful aero gains without the crosswind sensitivity of deeper profiles. The Felt Road One-Piece Integrated Cockpit, at 300g or less, keeps the front end clean and aerodynamic with fully internal cable routing. Continental GP 5000 S TR 700x28 tubeless-ready tires complete a spec that's ready to race without modification.\u003c\/p\u003e\n\n\n\u003ch3\u003eDesign Benefits\u003c\/h3\u003e\n\u003col class=\"design_benefits\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eAero performance verified in the wind tunnel.\u003c\/strong\u003e Felt's data puts the NEXAR within 4 watts of the fastest full-aero bikes at 40km\/h, with a 5% drag reduction over the previous AR. That's a meaningful gap to close — and the platform earns it through tube shaping, internal routing, and the integrated cockpit, not just clever marketing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGeometry built for sustained speed.\u003c\/strong\u003e The higher stack, shorter reach, and size-matched crank lengths mean you can hold the position across a four-hour ride that many aero bikes won't let you hold for one. Seven frame sizes make that fit accessible across a wide range of riders without compromise.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower meter included from the factory.\u003c\/strong\u003e The 4iiii non-drive side unit on the Ultegra crankset is a genuine spec highlight at this price. There's no retrofitting, no compatibility guesswork — it's there, it works, and the data is yours from ride one.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVision Metron 45 SL Carbon wheels.\u003c\/strong\u003e Forty-five millimeters is a well-considered depth for all-conditions riding — fast enough to produce real speed gains in flat road and headwind scenarios, manageable enough that crosswinds don't make the bike a handful. The carbon construction keeps weight in check.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinental GP 5000 S TR in 28mm.\u003c\/strong\u003e One of the fastest tubeless-ready road tires available, and 28mm gives you the compliance and flat resistance to ride confidently over varied road surfaces. The setup is tubeless-compatible out of the box — run sealant and you have an extremely capable all-conditions tire.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eFinal Take\u003c\/h3\u003e\n\u003cp\u003eThe Felt NEXAR Pro makes the case that serious aero performance and a riding position you can actually sustain are not mutually exclusive. Felt engineered the NEXAR platform specifically around that trade-off, and the Pro spec delivers it with a build — full Ultegra Di2, Vision carbon wheels, integrated 4iiii power meter, GP 5000 S TR tires — that leaves very little to add. If you want a Felt aero road bike that performs on race day and holds up on a long group ride the following weekend, the NEXAR Pro is where to start looking.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Felt","offers":[{"title":"FRD 12K \/ Glossy Burgundy \/ 45cm","offer_id":45405195501612,"sku":"9402600245","price":8899.0,"currency_code":"USD","in_stock":true},{"title":"FRD 12K \/ Glossy Burgundy \/ 48cm","offer_id":45405195534380,"sku":"9402600248","price":8899.0,"currency_code":"USD","in_stock":true},{"title":"FRD 12K \/ Glossy Burgundy \/ 51cm","offer_id":45405195567148,"sku":"9402600251","price":8899.0,"currency_code":"USD","in_stock":true},{"title":"FRD 12K \/ Glossy Burgundy \/ 54cm","offer_id":45405195599916,"sku":"9402600254","price":8899.0,"currency_code":"USD","in_stock":true},{"title":"FRD 12K \/ Glossy Burgundy \/ 56cm","offer_id":45405195632684,"sku":"9402600256","price":8899.0,"currency_code":"USD","in_stock":true},{"title":"FRD 12K \/ Glossy Burgundy \/ 58cm","offer_id":45405195665452,"sku":"9402600258","price":8899.0,"currency_code":"USD","in_stock":true},{"title":"FRD 12K \/ Glossy Burgundy \/ 61cm","offer_id":45405195698220,"sku":"9402600261","price":8899.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/FELT-NEXAR-PRO-ULTEGRA-R8150-BURGUNDY_7128c509-c7b7-4006-9162-8cae83d2c6cf.jpg?v=1774383499","url":"https:\/\/racycles.com\/pt\/products\/felt-nexar-pro-ultegra-di2-bike-6202","provider":"RA Cycles","version":"1.0","type":"link"}
