Bora Ultra WTO 35 C23 Disc Brake Tubeless Wheelset

Campagnolo Bora Ultra WTO 35 C23 Disc Brake Tubeless Wheelset

Unhindered aerodynamics, superior control at extreme speed, lightweight for the fastest climbs… The evolution of a generation, the new BORA ULTRA WTO – Wind Tunnel Optimized.

The one-of-a-kind carbon-fibre compound, in addition to enhancing the wheel performance, increases resistance to impacts and resilience against damages. Handmade with every drop of Italian artistry, the super-premium, aerospace-grade carbon fibre is used to achieve top performance and lightness.

Using their decades of experience, Campagnolo have crafted a front hub from carbon fibre –an exceptionally difficult but highly beneficial material to work with. This allows the BORA ULTRA WTO to be remarkably lightweight and a true step up in overall performance.

C-LUX is an evolution of the already premium finish of Campagnolo carbon rims. Their high gloss, mirror-like surface is not only high-quality, but is so flawlessly smooth that it doesn’t require lacquer, saving weight. The scientific precision of C-LUX also helps to ensure the safest possible seating of tubeless tires, increasing the pressure seal, ease of installation/uninstallation, and reducing the risk of abrasions to the bead.

Campagnolo’s wheel rims are crafted using their Handmade Ultra-Light Carbon, or H.U.L.C., process. This is the latest evolution of the unique rim moulding process that has been developed by Campagnolo during their twenty-five years of carbon manufacturing experience. Their H.U.L.C. technology ensures optimisation of the profiles, the quantity of carbon fibre and proprietary resin used – all contributing to increased stiffness and resistance.

The Aero Mo-Mag system takes aerodynamics to the next level. The internal fibreglass-reinforced polymer seats for the spoke nipples ensure perfect alignment with the spokes – reducing realworld stressors on the components. This innovative construction allows the wheels to be built lighter and, with a completely internal system, optimised for cutting through the wind.

These are the lightest BORAs ever at 1285g. By carefully selecting technology and making marked improvements, Campagnolo’s engineers have reduced weight by 100g compared to the previous version. Additionally, drag power is reduced by 80%W at a 15° sidewind angle. Enhanced rolling resistance and vibration absorption rounds off the BORA’s major improvements.

The carbon is uniquely laced with a single point of conjunction, compared to the industry standard four points – eliminating points of weakness. This one-of-a-kind lacing boosts rigidity and performance output. The fibres of the carbon are oriented to flow around the spoke hole, rather than being punched through for increased strength.

Through extensive research, Campagnolo have determined that our C23 rims are the perfect choice for riders aiming to improve their aerodynamics and control. The ‘teardrop’ shape of the rims is taken directly from nature and ensures the smoothest flow of air during the ride and can fit both wide gravel tyres and thinner road tyres.

The 7×3 G3 lacing geometry revolutionises traditional wheel spoke setups. Featuring groups of three parallel straight-head spokes in a 2:1 ratio, a design which enhances tension balance, increases stiffness, and amps up power transmission. This unique layout also improves load bearing, minimises weight, and reduces vibrations and rim deformations.

The final piece of the speed puzzle, the CULT ceramic bearings.
