Real Speed RS40 SLR Disc Wheelset
- Description
The Real Speed 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, the RS40SLR redefines what's possible in a 40mm depth wheel. 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.
The 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.
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 set is handbuilt in Canada, where skilled wheelbuilders hand-lace, tension, and true each wheel to exacting standards.
Key Features:
- 1,050g weight per set — the lightest wheel in the Realspeed lineup

- Torayca T1100G ultra-high-modulus carbon fiber construction

For 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.
