{"product_id":"realspeed-rs55-slr","title":"Realspeed RS55 SLR","description":"\u003cp\u003eThe Realspeed RS55SLR is the pinnacle of the RS55 line — an aero wheelset engineered without compromise, pulling out every stop in pursuit of pure speed.\u003c\/p\u003e\u003cp\u003eTipping the scale at just 1,150 grams for the set, the RS55SLR delivers a combination of depth and weight that seemed impossible until now. A 55mm profile built to cut through the air, at a weight that rivals wheels half its depth — this is a wheelset that lets you hold speed on the flats and still feel alive the moment the road tilts up.\u003c\/p\u003e\u003cp\u003eThe RS55SLR 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 every input translates immediately into speed.\u003c\/p\u003e\u003cp\u003eThe RS55SLR's 55mm rim profile was shaped and refined in a bicycle-specific wind tunnel, delivering a meaningful reduction in drag at race speeds, so less energy is spent fighting the wind and more is left for the finish.\u003c\/p\u003e\u003cp\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\u003cp\u003eEvery set is handbuilt in Canada, where skilled wheelbuilders hand-lace, tension, and true each wheel to exacting standards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1,150g weight per set — exceptional weight for a 55mm aero
