Campagnolo Carbon Wheelset | BORA Ultra WTO 45mm, Disc Brake

Bora Ultra WTO 45 Disc Brake
Campagnolo’s Bora Ultra WTO 45 has the perfect balance of speed, agility, and stability, making it the best choice for all-around riders. The rim’s versatile design takes account of real-world riding conditions, not just those created in a wind tunnel, and the result is the most efficient drag-reducing rim shape available.

Now even lighter, thanks in part to its Hand Made Ultra-Light Carbon (H.U.L.C.) construction, the Bora Ultra WTO 45 has slimmer Aero Elliptical spokes and hidden nipples to help slice through the air. Campagnolo’s beautifully molded carbon hub body is securely bonded to a light aluminum hub flange, and integrated radial spoke seats ensure perfect alignment. A uniquely stunning C-LUX finish and new, subtle Bora Ultra graphics ensure the new wheels have the show to match their go.

Campagnolo’s CULT ceramic bearings spin effortlessly within both the front aerodynamic carbon body and the rear aluminum shell of the disc hubs. The rear oversized 36-tooth ratchet system can be driven by N3W, XDR, or HG freehub bodies.

The 2-Way Fit rims are ready for immediate tubeless use without rim tape, designed for tire widths from 23mm, they’re aerodynamically optimized for 25mm tires.

Main Benefits

Undeniable efficiency

• Overall wheel efficiency is determined by overcoming aerodynamic resistance, rolling resistance, and the effects of weight and gradient.
• Rolling resistance for this rim profile was found to be lower with a 19mm internal width rim bed, particularly with 25mm or 28mm tires, but aerodynamics are optimized with 25mm.
• With a system weight of 87kg, a 25mm tire’s rolling resistance at 40km/h is tubular 30 watts, clincher 28 watts, and tubeless 25 watts. Therefore Bora Ultra WTO has 2-Way Fit rims for tubeless, tubeless-ready, or clincher tires.

Perfect alignment

• Campagnolo molds the nipple and valve holes into the rims, so no carbon fibers are cut by drilling
• Each spoke hole has an internal nipple seat, wrapped into the rim’s carbon layup, which is specifically aligned to the intended hub
• Aero Mo-Mag nipples are perfectly aligned with each spoke for a more accurate wheel build, with reduced localized stress and improved fatigue life.

Stop and go

• All of the new Bora Ultra WTO wheels are designed for AFS (centerlock compatible) disc rotors.
• Campagnolo’s unique G3 spoke system counteracts the main source of torque at each hub.
• CULT ceramic bearings keep the Bora Ultra WTO hubs spinning freely for 5 ½ times longer than standard steel bearings
• The oversized 36-tooth ratchet freehub is fast to engage and very durable, plus it accepts N3W, XDR, and HG freehub bodies.

Technologies

CULT - Ceramic Ultimate Level Technology
Campagnolo’s finest ceramic bearings are fitted to only the very best hubs and cranksets and are a significant upgrade from all other bearings. Their premium quality ceramic balls are incredibly round and hard and rotate within wear-resistant stainless steel races, which are engineered to micron-precise tolerances, maximizing efficiency and durability. They won’t deform or corrode, perform consistently over time, and only need periodic cleaning and then lubricating with light synthetic oil.

CULT bearings have a friction coefficient 40% lower than standard sealed bearings, and in tests, can spin for 5 ½ times longer.

G3 Geometry

• Campagnolo’s unique G3 spoke pattern comprises groups of three parallel straight-pull spokes, arranged in a 2:1 ratio. Having twice as many spokes on one side allows wheels with G3 to counteract the asymmetric drivetrain and braking forces acting on them, creating more symmetric performance and equalizing the load. Energy transfer and lateral rigidity are improved and spoke tension is optimized, reducing stress and increasing lifespan.
• All Campagnolo disc brake wheels utilize the G3 pattern, the front wheel has more spokes on the disc brake side, and the rear is biased to the drivetrain side.

Next 3 Ways

N3W Is Our Future: A Single Standard to Manage
All the Campagnolo Cassettes… Present, Past, And... Still to Come!N3W is a patented standard for a freewheel body engineered to house 11-, 12- and 13-speed cassettes with 9-, 10- and 11-tooth starting sprockets: NEXT 3 WAYS.
It is also still compatible with older 9- and 10-speed cassettes.

One Ring to Rule Them All

• N3W has the same groove profile as the classic Campagnolo body but it is 4.4 mm shorter, making it lighter.
• N3W is directly compatible with the new Campagnolo cassettes with 9- and 10-tooth starting sprockets.
• To make it compatible with ALL of today’s cassettes with 11-tooth starting sprockets, simply use the N3W ring (kit ring + ring code AC21-N3W) which makes them the same length as the classic body.

Aero Mo-Mag
The innovative Mo-Mag system allowed external spoke nipples to be positioned from inside the rim using a magnet, with no need to create additional holes in the rim bed for them. Aero Mo-Mag takes it a step further, with a completely internal, hidden system, which maximizes aerodynamics and allows the rim to be built lighter.

The internal fiberglass-reinforced polymer nipple seats are specific to each rim and hub combination, ensuring perfect spoke and nipple alignment, and reducing real-world stress on each component. Any spoke tension adjustment can still be easily carried out in a conventional way, using the supplied proprietary Torx tool.

H.U.L.C. Handmade Ultra-Light Carbon
Bora Ultra WTO rims are built using Campagnolo’s new H.U.L.C. process, which is an evolution of the unique carbon molding process that already creates defect-free rims requiring no additional finishing. Optimizing the carbon fiber and proprietary resin ratios used, alongside process improvements, guarantees consistently accurate forming of the 2-Way Fit tire hooks and other details.

The Bora Ultra WTO rims are the lightest Campagnolo have ever made in each depth, but still, deliver identical stiffness, and improved mechanical resistance, when compared to the already notably reliable non-H.U.L.C. rims.

C-LUX Finish
Fast wheels must be functional and look the part too, however, so the rim (and front hub) also sports a stunning mirror-like Campagnolo Luxury (C-LUX) finish.
This C-LUX finish is so pristinely smooth and without defects that it doesn’t require lacquer, saving weight. When applied to the rim bed, as done for the first time with the new Bora Ultra WTO, the scientific precision of C-LUX also helps to ensure the safest possible seating of tubeless tires, increasing their pressure seal, the install/uninstall ease and further and further reducing the risk of abrasions to the bead.
