The Realspeed RS40 SLR is the pinnacle of the RS40 line — a no-compromise wheelset built with one goal: maximum performance, full stop.
At an astonishing 1,050 grams for the set, it redefines what's possible in a 40mm depth wheel — acceleration feels instantaneous, climbs feel shorter, and direction changes happen the moment you think them.
The 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. The hooked rim design features a modern 24mm internal width and 30mm external width, striking the ideal balance between wide tire support, aerodynamic efficiency, and compatibility with a broad range of tubeless and clincher tires.
Every RS40 SLR is handbuilt in Canada, where skilled wheelbuilders hand-lace, tension, and true each wheel to exacting standards. It retains the ultra-high-modulus Torayca T1100G carbon rim and ceramic bearings of the SL, then goes further with Vonoa full carbon fiber aero bladed spokes with titanium end fittings — dramatically reducing unsprung weight while increasing torsional stiffness for more direct power transfer and sharper handling.
At just 1,050g for the set — the lightest wheel in the Realspeed lineup — the RS40 SLR is the ultimate expression of what a lightweight climbing wheel can be, for riders who refuse to leave performance on the table.
