Fulcrum WIND 40 Disc-Brake 2-Way Fit Wheelset

The Fulcrum WIND 40 Disc-Brake 2-Way Fit Wheelset is a carbon aero road wheelset built for riders who want a genuine aerodynamic upgrade without giving up everyday versatility. At 40mm, the rim depth sits in the middle ground that works for most road riding — enough depth to feel a real difference on flatter roads and in a fast group ride, without the crosswind sensitivity or handling penalty of a much deeper rim.

Fulcrum builds the rim to a disc-brake-specific carbon layup, with a 19mm internal width, 27mm external width, and 4mm-thick sidewalls at the bead. That width supports modern road tires properly, letting them sit at their intended shape rather than pinching narrow at the rim. The 2-Way Fit design is the more distinctive piece of engineering here: the internal rim bed is fully hole-free, with the spoke nipples seated inside the rim and positioned magnetically during assembly rather than accessed through drilled holes. That construction gives the WIND 40 tubeless compatibility out of the box while still working with a standard clincher tire and tube if that's what a rider prefers, without ever compromising the airtight seal tubeless setups need.

The wheelset runs on CNC-machined aluminum hubs paired with 24 straight-pull spokes per wheel, laced in a 2:1 pattern. The front wheel carries 16 spokes on the brake side, where disc braking forces concentrate, while the rear shifts more spokes to the drive side, since the rear hub only handles roughly 20 percent of a bike's total braking load compared to the front. That asymmetric lacing is a deliberate response to where the actual stress lands on a disc-brake wheel, rather than a leftover pattern borrowed from rim-brake design. Rotors mount via Centerlock, and the hub is available with Shimano HG11, SRAM XDR, or Campagnolo freehub bodies, covering the drivetrain standards most riders are already running.

Fulcrum lists the wheelset at approximately 1,620 grams for the pair, a competitive weight for a 40mm carbon aero wheel that's still built to handle real road riding rather than just race-day duty. Axle compatibility is thru-axle, 12x100mm up front and 12x142mm in the rear, matching the standard that most modern disc-brake road frames use. That combination of moderate weight, aero depth, and thru-axle compatibility makes the WIND 40 a straightforward fit for most current disc-brake road bikes without needing an adapter or a special build.

This wheelset suits a road rider who wants one set of wheels that performs well across most riding situations — club rides, road races, long weekend rides, and everything short of a dedicated time trial setup. The tubeless-or-clincher flexibility means a rider can start on tubes and move to tubeless later without buying a new wheelset, and the 40mm depth is shallow enough to stay predictable in variable wind while still delivering a real aerodynamic benefit over a shallow alloy wheel. For a rider upgrading from stock wheels who wants genuine performance without specializing into a single riding discipline, the WIND 40 is built for exactly that use case.
