Bora wheels optimized for disc brakes.
We're used to seeing the mid-depth Bora wheelset getting a
lot of action from riders on Team Movistar, UAE Team Emirates, and
Lotto-Soudal, and for good reason. It's simply a great all-around wheelset
that's light enough to satisfy the climbers and GC hopefuls while summiting
hors catégorie climbs during the grand tours, plenty stiff and aero enough for
the sprinters during fast 40+ mph sprint finishes and reactive for the always
attacking puncheurs over lumpy Ardennes classics with 20% muurs on repeat. Also
don't forget that this wheelset survives the 29 sectors of cobbles at Roubaix
year after year. This shouldn't surprise us as the Bora name has always been
synonymous with blending aerodynamics, excellent handling, reliability, and
power transfer since its introduction in 1994. Campagnolo updated the wheels as
needed to deal with newer bikes and rider's demands over the years and now with
more pros and other discerning cyclists choosing discs for their braking needs,
the Bora One 35 Disc Brake Clincher Wheelset is poised to provide race-ready
performance and everyday reliability on any ride.
Starting with the rim, the clincher compatibility allows
this wheelset to be a little more user-friendly on the days when you're not
pinning on a race number. The full-carbon construction is both lightweight and
strong and the rims have gotten wider on this newer generation, plumping up
from 20 to 23.5 millimeters. This width is designed for the newer standard of
25mm tires allowing for greater volume, better handling and cornering, lower
rolling resistance, and an overall smoother ride. The wider rims also
contribute to better lateral stiffness for improved power transmission and
bolster better aerodynamics when paired with the wider tires. These gains in
ride quality also come with an overall weight loss since the cross-section of a
wider rim lets Campagnolo use less material while offering a rim of equal
strength. The use of a rotor as a braking surface instead of on the rims
allowed Campy to further optimize the layup to save weight and focus on the
ride quality instead of the heat and pressure requirements of rim braking.
Additionally, Campy uses an advanced resin that creates a brilliant finish,
without the need for a final clearcoat, that's highly durable, and is UV
resistant. Finally, Rim Dynamic Balance technology creates a perfectly balanced
rim that is more stable at speed through the use of structural counterweights.
At the center of the wheels are hubs made of aluminum with
completely new flange designs to cope with the additional forces and torque
transfer across the hub that's seen with disc brakes. Inside the shells are
Campy's Ultra Smooth Bearings (USB) using legendary Campagnolo ceramic bearings
keeping things rolling smoothly and a user adjustable lockring allows you to
adjust the preload for wear while keeping drag to a minimum. Axles come in at
12 x 100mm front and 12 x 142mm rear matching the current spacing on modern
road disc framesets and the centerlock rotor mounting allows for multiple rotor
options. The freehub body accommodates Campagnolo cassettes.
Campy modified its famous G3 spoke pattern to compensate for
the different loads the wheel now faces with disc use. The symmetric, radially
laced front wheel used on the rim brake wheel now gets its own version of G3
lacing while the already asymmetric rear receives slight modifications to
create space for the rotor and better balance spoke tension between the drive
and disc sides.
Campagnolo finishes off the Bora One 35 Disc with a few more
thoughtful details. Black anodized self-locking nipples eliminate the
possibility of any of the bladed stainless steel spokes from losing tension.
MoMag technology allows Campy to place the nipples in the rim without the need
for drilling the outer wall of the rim, improving the carbon integrity and
stiffness. Campy constructs and lays-up all of the carbon for the Boras in
Vicenza, and every piece is X-rayed to scan for imperfections.
