Fulcrum WIND 55 Disc-Brake 2-Way Fit Wheelset

The Fulcrum WIND 55 Disc-Brake 2-Way Fit Wheelset is Fulcrum's deep-section carbon road wheel, built around a 55mm rim depth for riders who want an aero wheel that still handles the realities of everyday road riding — tubes, tubeless, and a range of tire widths — without forcing a choice between them. At roughly 1,680 grams for the pair, it sits in the category of carbon aero wheels built for fast group rides and racing rather than pure hillclimb weight, and the deep rim profile is the main lever Fulcrum pulls for speed on flatter, faster terrain.

Fulcrum's 2-Way Fit technology is the core of how this rim handles tires. It's a hooked rim profile engineered to work with both tubeless and standard clincher tube-type tires on the same rim, with a shaped valve area that Fulcrum designed to keep a tube seated precisely and reduce the risk of air leaks from a poorly seated valve on tubeless setups. In practice, that flexibility means a rider can run this wheelset tubeless for lower rolling resistance or fall back to a tube and clincher tire without needing a different wheel — useful for anyone who wants one aero wheelset that covers racing and everyday training. The rim carries a 19mm internal width and 27mm external width, dimensions built for narrower, faster-rolling road tires rather than the wider gravel-oriented volumes some modern aero wheels have shifted toward.

The wheelset uses 24 spokes front and rear, built with Fulcrum's 2:1 spoke lacing for disc brake wheels — 16 spokes on the drive side and 8 on the non-drive side. That asymmetric spoke count exists to counteract the tension imbalance a disc rotor and cassette naturally create on one side of a wheel, which is a meaningful detail on a disc-brake specific wheelset like this one rather than a rim-brake wheel adapted to discs. Braking runs through a Center Lock disc interface on both wheels, and the wheelset uses standard 12x100mm front and 12x142mm rear thru-axle spacing, covering the large majority of current disc-brake road frames and forks.

This build is available through RA Cycles with a choice of Campagnolo, Shimano/SRAM (HG), or SRAM XDR freehub bodies, so it can be matched to whatever drivetrain is already on the bike without needing a separate freehub purchase. That range of freehub options is worth noting for anyone running Campagnolo specifically, since compatible carbon aero wheelsets at this depth and price aren't always offered with a Campagnolo option.

The WIND 55 ships in a Black colorway and is priced at $1,650.00 through RA Cycles. For a rider who wants a genuine aero wheel — deep enough to matter on flat, fast rides — but doesn't want to give up the option of running a tube if a tubeless setup ever fails mid-ride, the 2-Way Fit rim design is the wheelset's real selling point. It's built for riders logging miles on pavement who care more about consistent speed and tire flexibility than shaving grams for a climb.
