Fulcrum’s top-level Razing Zero wheel line gets a new, more affordable alloy all-rounder in the new Racing Zero Cmptzn DB. Using the same premium tubeless wheel spec with aluminum spokes, carbon hubs & ceramic bearings as in the top Razing Zero Carbon DB, the new black label Racing Zero Cmptzn rolls out a lightweight disc brake wheelset that’s ready to hit the road at about half the price of carbon.
Fulcrum Racing Zero Cmptzn DB aluminum road wheels
Fulcrum’s latest top-spec aluminum disc brake Racing Zero wheels take the name Cmptzn, dropping all the vowels out of the former rim brake Competizione version. (Where we’re going, we don’t need vowels!) Besides dropping a few letters, these new disc brake wheels step up the stealth factor in all black-on-black, while retaining the premium tech that makes Racing Zero well suited for everything from road racing to everyday all-road riding.
Racing Zero Cmptzn DB – Tech details
At the heart of a Racing Zero Cmptzn DB wheelset are the oversized machined hubs, with a carbon front hubshell. Inside of that, the same premium CULT (Ceramic Ultimate Level Tech) ceramic bearings on treated steel races that make Campy wheels spin smoothly are lubricated with oil (vs. heavier grease) for reduced friction & greater longevity. Hubs all spin on aluminum axles for 12mm thru-axles only, with AFS centerlock rotor interfaces, and Campy, HG11 & XDR compatibility.
The wheels get 2:1 spoke lacing both front & rear to better balance spoke tension from disc brake to driveside. And they use the proven strong flattened aero, double-butted alloy spokes with straight pull heads. Both Campagnolo & Fulcrum talk up this setup for creating a strong & responsive wheel, which I’ve seen proven out on the road. While replacement spokes can’t simply be picked up in your local shop, I’ve had one snapped in a pretty hairy cyclocross pileup that didn’t even knock the alloy rim out of true, then had the spoke replaced two days later.
The Italian-made 30mm deep 700c aluminum rim itself isn’t to be overlooked either. Fulcrum uses a 6082-T6 alloy said to be “Pre-Aged” for improved strength & resilience. The rims get wide for road 19mm internals (23.8mm external) with 2-Way Fit tubeless-ready hooked beads. Then Fulcrum machines them down in between each of the evenly space 21 spokes front & rear to minimize weight. Fulcrum does not drill the rim bed for each spoke, instead using their Mo Mag tech to guide nipples into place via the valve hole, making for a tape-free tubeless setup and less extra weight at the rim bed.
Fulcrum claims a complete wheelset weight of 1570g for the Racing Zero Cmptzn DB, and rates them for rider+bike+gear of up to 120kg/265lb.
