It's the kind of wheel that disappears beneath you, letting you ride on feel rather than fighting inertia.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThat exceptional weight comes from a rim built with Torayca T1100G carbon, an ultra-high-modulus fiber that allows for a lighter, stiffer layup than standard carbon construction — shaving grams without sacrificing strength or ride quality. That low weight doesn't come at the cost of aerodynamics: the RS40SL's 40mm rim profile was shaped and refined in a bicycle-specific wind tunnel, so you still get a meaningful aero advantage on the flats and rolling terrain.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe hooked rim design features a modern 21mm internal width and 28mm external width, striking the ideal balance between wide tire support, aerodynamic efficiency, and compatibility with a broad range of tubeless and clincher tires.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eEvery set is handbuilt in Canada, where skilled wheelbuilders hand-lace, tension, and true each wheel to exacting standards.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eKey Features:\u003c\/p\u003e\n\u003cul class=\"ul1\"\u003e\n\u003cli class=\"li1\"\u003e1,295g weight per set — our lightest RS40 build\u003c\/li\u003e\n\u003cli class=\"li1\"\u003e40mm depth profile, shaped in a bicycle-specific wind tunnel for real-world aero performance\u003c\/li\u003e\n\u003cli class=\"li1\"\u003eTorayca T1100G ultra-high-modulus carbon fiber construction\u003c\/li\u003e\n\u003cli class=\"li1\"\u003eHooked rim design — 21mm internal width \/ 28mm external width\u003c\/li\u003e\n\u003cli class=\"li1\"\u003eSapim CX-Ray aero bladed spokes for reduced weight and drag\u003c\/li\u003e\n\u003cli class=\"li1\"\u003eCeramic bearings for minimal rolling resistance\u003c\/li\u003e\n\u003cli class=\"li1\"\u003eInternal spoke nipples for a clean, aerodynamic profile and added protection\u003c\/li\u003e\n\u003cli class=\"li1\"\u003eHandbuilt in Canada for superior quality control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"p1\"\u003eWhether you're attacking a hilly road race, racing a crit, or looking for the lightest possible edge on race day, the Realspeed RS40SL gives you uncompromising performance in a featherweight package.\u003c\/p\u003e","brand":"Real Speed","offers":[{"title":"Shimano","offer_id":49126766477567,"sku":"210000028482","price":1799.0,"currency_code":"CAD","in_stock":true},{"title":"Sram","offer_id":49126766510335,"sku":"210000028483","price":1799.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0509\/5317\/files\/RealSpeedRS40SLDiscWheelset2.webp?v=1788187953","url":"https:\/\/www.racersportif.com\/products\/real-speed-rs40sl-disc-wheelset-1","provider":"Racer Sportif","version":"1.0","type":"link"}
