{"product_id":"real-speed-rs40-disc-wheelset","title":"Real Speed RS40 Disc Wheelset","description":"\u003cp class=\"p1\"\u003eBuilt for riders who want to feel every gram of savings, the Realspeed RS40 is a lightweight, agile wheelset that doesn't ask you to sacrifice speed to get there.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eAt just 1,395 grams for the set, the RS40 accelerates and climbs with a responsiveness that heavier wheels simply can't match — surge out of a corner, attack a punchy rise, or follow a late attack without hesitation. 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 low weight doesn't come at the cost of aerodynamics. The RS40'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 — an efficient, versatile depth that keeps you fast everywhere, not just on the climbs.\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. This craftsmanship-first approach means tighter tolerances, better durability, and a ride quality that mass production simply can't replicate.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eKey Features:\u003c\/p\u003e\n\u003cul class=\"ul1\"\u003e\n\u003cli class=\"li1\"\u003e1,395g weight per set — built for climbing and acceleration\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 T800 full 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\"\u003eInternal spoke nipples for a clean, aerodynamic profile and added protection\u003c\/li\u003e\n\u003cli class=\"li1\"\u003eStainless steel spokes for durability and reliable performance\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 an everyday wheel that rewards every effort, the Real Speed RS40 gives you the agility, the efficiency, and the ride feel to do it all.\u003c\/p\u003e","brand":"Real Speed","offers":[{"title":"Shimano","offer_id":49126564233471,"sku":"210000028478","price":1299.0,"currency_code":"CAD","in_stock":true},{"title":"Sram","offer_id":49126564299007,"sku":"210000028479","price":1299.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0509\/5317\/files\/RealSpeedRS40DiscWheelset.webp?v=1788186457","url":"https:\/\/www.racersportif.com\/products\/real-speed-rs40-disc-wheelset","provider":"Racer Sportif","version":"1.0","type":"link"}
