The Fulcrum Racing 1 2-Way Fit Wheelset is a prime wheel for racing with their semi-aero rims and bladed spokes. Their rim construction gives you the versatility of running these wheels with clincher or tubeless tires, an advantage over the sister wheel of the same name.

If you're familiar with Fulcrum wheels, you know the company is an extension of Campagnolo. This isn't just on paper and Fulcrum wheels get every bit of Campagnolo's engineering experience and technology, as evidenced by the rim construction of the wheels in the 2-Way Fit series. 2-Way Fit is Fulcrum's way of describing the rim construction that is suitable for both tubeless and clincher tires. Tubeless tires have been used in the mountain bike world for years for the superior ride they provide. Running your wheels tubeless provides better traction since you can run the tires at a lower pressure without worrying about rolling the bead off the rim. Additionally, running a tubeless set up on your road bike eliminates the pinch flats you’d get with regular clinchers. These benefits are akin to what you get from tubular tires, but with an easier installation process.

The Racing 1 wheels use an all-aluminum hub shells, in contrast to the carbon/aluminum version on the Racing Zero, but they're lightweight nonetheless, in part because of the aluminum axles. Smooth-running stainless steel hub bearings keep friction minimized, which nicely complements the Racing 1's aerodynamic advantages. Since the rims are designed to accommodate tubeless tires, Fulcrum uses MoMag technology, to pull spoke nipples from the valve hole around the hollow interior of the rim to get them into their respective positions. The outer wall of the rim is pierced only for the valve stem and doesn't require any rim strips whether or not you choose to ride tubes or tubeless. Fulcrum machines excess aluminum from the rims between each spoke to reduce any unnecessary weight. However, they intentionally left the area near the valve stem hole unmachined to counteract the mass of the opposing rim joint. They call this Dynamic Balancing and the result is a wheelset that rolls smoothly at any speed.

The front wheel has a 23mm deep rim and 16 radially laced spokes. The rear wheel has a 27mm deep rim and 21 spokes using Fulcrum's Two-to-One pattern. The non-drive side has 7 radial spokes and the drive side uses 14 tangentially laced spokes anchored to the oversized right side flange on the rear hub. The Two-to-One pattern ensures a greater transfer of your power input and a better balance of tension in the wheel for greater durability.

Going tubeless always calls into question what to do if you get a flat. The good news is, if you puncture the tire mid-ride you can unthread the 2-Way Fit valve and install a standard inner tube. Or, alternatively, you can run your Racing1's like standard non-tubeless clinchers with whatever tire/tube combo you'd like.

The Fulcrum Racing 1 2-Way Fit Wheelset comes with steel bodied quick releases with aluminum end caps. They are available with either Campy or Shimano/SRAM compatible freehub bodies. Note: The Shimano/SRAM freehub is compatible with an 11-speed cassette.
