Acceleration feels instantaneous, climbs feel shorter, and direction changes happen the moment you think them — this is a wheelset that gets out of the way entirely, leaving nothing between you and the effort.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe RS40SLR retains the ultra-high-modulus Torayca T1100G carbon rim and ceramic bearings of the SL, but takes performance further with Vonoa full carbon fiber aero bladed spokes, finished with titanium end fittings. Replacing traditional steel spokes with carbon dramatically reduces unsprung weight at the rim and hub, while significantly increasing torsional stiffness — meaning power transfer is more direct, handling is sharper, and the wheel responds to every input with less flex and less lag.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe RS40 SLR's 40mm rim profile was shaped and refined in a bicycle-specific wind tunnel, delivering a genuine aero advantage on flats and rolling terrain to complement its class-leading weight.\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\"\u003e1,050g weight per set — the lightest wheel in the Realspeed lineup\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\"\u003eVonoa full carbon fiber aero bladed spokes with titanium end fittings — reduced unsprung weight, increased torsional stiffness\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\"\u003eFor riders who refuse to leave performance on the table, the Real Speed RS40 SLR is the ultimate expression of what a lightweight climbing wheel can be.\u003c\/p\u003e","brand":"Real Speed","offers":[{"title":"Shimano","offer_id":49126988185855,"sku":"210000028486","price":2199.0,"currency_code":"CAD","in_stock":true},{"title":"Sram","offer_id":49126988251391,"sku":"210000028487","price":2199.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0509\/5317\/files\/RealSpeedRS40SLRDiscWheelset1.webp?v=1788190108","url":"https:\/\/www.racersportif.com\/products\/real-speed-rs40-slr-disc-wheelset","provider":"Racer Sportif","version":"1.0","type":"link"}
