The rear Zero Competition wheels feature the largest improvements with both Cult bearings and the new Mega Drive Side flange (Fulcrum)

Beginning in April, Fulcrum will offer new
limited edition ‘Competition’ versions of the Racing Zero and Racing 1. The
Italian manufacturer plans to only make a few hundred pairs available

The new Limited Edition Racing Zero Competition
wheels (US$TBC/£1099.99) are factory tuned with two specific features:
adjustable Cult bearings, which Fulcrum claim are nine times
smoother than standard steel cartridge bearings.

The smoother bearings are paired with the new
‘Mega Drive Side’ rear hub flange, which is said to make the rear wheel 8-percent stiffer
(6.2kg/mm to 5.7kg/mm) in torsional deflection, when compared to the standard
2012 Racing Zero. It’s also interesting to note the new Mega Drive Side flange
has no bearing on compliance, or vertical stiffness, according to Fulcrum

Fulcrum say the upgrades make the new wheels lighter, with a 25g weight saving from the rear wheel (now 800g). The limited edition Zero Competition wheels also
sport all-new graphics.

Racing 1 Competition sees a 43g weight reduction and an 8-percent increase in stiffness

The Racing 1 Competition model (US$TBC, £799.99)
see even greater benefits from the Mega Drive Side structural change; it is 5-percent
lighter — dropping from 851g to 808g — and
sees the same 8-percent increase in torsional stiffness; of course, they
too get a new graphics treatment to set them apart. The Racing 1 Competition wheels run on standard bearings, thus the difference in price from the Zeros.
