Designed for cyclists with a love for speed, the WTO family welcomes its very first high profile aerodynamic disc brake wheel, the Bora WTO 60. Campagnolo have taken their extensive knowledge and pushed the limits of research and development of wheels in the category further still, creating a wheelset with a high profile which can transfer all the aerodynamic advantages to the road. The design of each wheel component enables maximum aerodynamic penetration, so that the wind stops being a hindrance to the cyclist and, at certain angles, becomes a help. The wheel features unidirectional carbon rims with a rounded-profile optimised in the wind tunnel, new aerodynamic aluminium hubs and the ceramic USB cup-and-cone bearing system. Every design decision has been determined with the sole goal of optimising performance. The profile of the rim, which has an internal width of 19mm, makes a perfect pairing with 23, 25 and 28mm tyres. Thanks to 2-Way Fit technology, Campagnolo guarantees complete compatibility with both clincher and tubeless tyres. The hole-free upper bridge, achieved through the patented MoMag system, saves weight, increases stiffness, and allows for tubeless tyres to be fitted without requiring any tape. Maintaining and cleaning the wheel during tyre replacement has never been easier. These wheels were made for extreme performance, the Campagnolo mantra is reliability: the G3 spoke pattern with double spokes on the left of the front wheel ensures balanced and safe braking in all conditions. The Bora WTO 60 Disc Brake wheel is entirely hand-assembled by a specialised Campagnolo technician and is 100% checked using electronic instrumentation. This procedure ensures that every single Campagnolo wheel offers maximum performance and reliability BORA WTO 60 DB: made for winning in sprint finishes, circuit races, time trials and triathlons. Available with Campagnolo 10/11/12s, Shimano/SRAM 10/11s or XDR 12s freehub bodies. The WTO™ Advantage 60mm – the essence of aerodynamics The design of the rim enables maximum aerodynamic penetration: at wind angles between 10° and 20° (a situation that accounts for 80% of time on the saddle), this wheel is unequalled when it comes to overcoming drag. The streamlined design of the central part of the hub and the special design of the flanges decrease the frontal area of the component reducing airflow turbulence. The 24-spoke pattern, along with their elliptical cross section, results in a far superior drag reduction. Fast…and Fluid The well-known USB cup-and-cone bearing system guarantees 50% greater smoothness than standard bearings. The 2-Way Fit profile allows you to fit either a clincher tyre or to opt for a tubeless tyre and benefit from the lowest rolling resistance The 19mm inner width enables you to fit 23, 25 and 28mm tyres, with perfect pairing of the rim-tyre system Choose Aero, but make it Campagnolo The 60mm profile allows the transfer of all the benefits of aerodynamic optimisation that can’t be achieved with lower profiles. The wheel structure enables minimal energy dissipation, transferring all the energy produced by the cyclist to the asphalt. A 60mm profile with a wheelset weight of 1590g makes it the perfect partner to win sprint finishes, circuit races, time trials and cycling sections in triathlons.

Wider Carbon Fibre Rim for Better Aerodynamics The 303 Firecrest Tubeless Disc brake wheels were designed using real-world direct measurements (vs. primarily wind tunnel or computer simulation). This included Zipp’s RollingRoad™ Testing Protocol. The results were huge. Its rim is slightly more bulbous in design than its predecessor, with a 30mm outside width, a 25mm internal width and a 40mm rim depth. The profile provides low drag and an improved transition between rim and tyre, boosting aero efficiency on the road. Faster Performance These wheels are faster, lighter and more capable over varied terrain, whether the surface is tarmac in all its conditions or no tarmac at all. Deeply rooted in Zipp’s drive to conquer the Spring Classics, the revised 303 Firecrest is redesigned with a purpose-made approach for the demands of modern road bikes. This is the first Zipp wheelset to feature TSE™ Technology (Total System Efficiency). The 303 Firecrest’s precise rim layup results in greater all-around efficiency for greater speed through reduced wind resistance, rolling resistance, a lower weight, increased durability and vibration losses. More Comfortable Ride on Mixed Terrain The wide rim stance also features less tyre deflection for reduced rolling resistance. The combination of the wider tyre, increased tyre volume and lower tyre pressure reduces rider fatigue. This is because the ride is smoother over imperfect surface conditions as the tyre and wheel system absorbs the shaking, not the rider. At the centre of the 303 Firecrest Tubeless Disc brake is a versatile and durable hubset, the German-engineered ZR1 DB. This hubset features 66 points of engagement for quicker pedalling response. The 303 Firecrest Tubeless Disc-brake wheelset is for those after greater efficiency for greater speed. The payoff is a smoother, faster ride. Additional Features: Updated Zipp graphics and cosmetic identity that scream speed Versatile endurance wheelset for the modern road bike with tubeless and hookless rim profile Lower in weight - a 300g weight reduction than its predecessor, making it nimble and fast Tubeless Made Easy, optimised tyre bed sign allows for simple tool-free installation and removal with no need for an air compressor to seat the tyre Ultra-wide 25mm rim profile creates a better tyre interface to be fast on or off the road 40mm rim depth makes a light and aero wheel in every situation ZR1 DB hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement Ships with 12mm front and rear end caps Centre locking rotor interface Lockring is included with the wheels Lifetime Warranty
