Real Speed RS40 Disc Wheelset

Built 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.

At 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.

That 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.

The 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.

Every 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.
