One wheel two-ways

Tubless tires have finally met the road. Fulcrum Racing's Zero 2-Way Fit Wheelset features the same design as their sister wheels but are inbued with the option of running your wheels as clincher or tubeless. As an added bonus, they are 50 grams lighter than the Racing 1 wheels.

Fulcrum uses 2-Way fit as its designation for rims that are able to be run with traditional tubes or as tubeless. And while tubeless tires for trail riding have been popular for quite some time, the advantages to running them on the road are just becoming more obvious. For example, you are able to run slightly lower tire pressure which provides added traction and grip in turns. Also, pinch and snake bite flats are virtually eliminated. They provide all of the benefits of tubular tires with plus of being easy to install.

Compared to the aluminum construction of the Racing 1's hubs, the Racing Zero's use a carbon fiber and aluminum shell. This instantly reduces the weight of the wheel set. And Fulcrum didn't stop there. Aluminum axles and bladed spokes are mated with alloy nipples. Furthermore, the rims have been machined between the spoke holes to reduce weight. At the same time, they lack machining at the valve stem hole. And while this may seem like a subtle detail, this small amount of aluminum helps to counterbalance the weight of the opposing rim joint.

If you look closely, you'll notice that the wheels have two different depths-the front is 26mm deep while the rear stands at 30mm deep. Although the difference is small, it helps the front wheel to be more stable in cross winds while stiffening the rear for more efficient power transfer. The front wheel has 16 radially laced spokes, and the rear has 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 trueness and durability.

The Fulcrum Racing Zero 2-way Fit Wheelset comes in One color. The wheels come with stainless-steel bodied quick releases with aluminum dies and are available with either Campy or Shimano/SRAM compatible freehub bodies. Note: The Shimano/SRAM freehub is compatible with an 11-speed cassette.

Good racing wheels

  • Familiarity:I've put it through the wringer

I bought this wheelset under the advise of two bike shop owners whose opinions I respect. I own both this and a set of the Dura Ace C24 TLs. Here is how I compare the two: The longer, straighter and flatter the ride, the more I prefer the Shimano wheelset. The shorter, curvy, and steeper the ride, the more I prefer the Fulcrum. Crits: Fulcrum. Century rides: Shimano. UNLESS there is a lot of wicked descending with tight turns, then I'd go with Fulcrum. The Shimano wheels take up more road abuse and leave you less fatigued and provide a ride quality I prefer for day to day riding/training. And they are plenty stiff. I have won more than a few Strava sprint KOMs on the Dura-Ace wheels. The Fulcrums are stiffer and have a harsher ride but cornering hard and jumping into a sprint, they transfer power very well. If I could only own one pair of wheels, I'd go with the Dura-Ace. BTW fulcrum wheels do not have stainless steel spokes as listed in the description above. FWIW I have used both wheel sets for two years on a Time "World Star".

Best aluminum wheelset I have ridden.

  • Familiarity:I've used it several times

I have ridden about 750 miles on this wheel set and have only great things to say about them. I mounted tubeless Schwalbe Ultremo ZX's on them and could not be happier. Not sure how to explain how smooth and fast they are. The ceramic bearings make them super fast and the tubeless tires are more comfortable than running with tubes. I expect once people try them, tubes will be a thing of the past as in Mountain biking.
