An AC3 (All Conditions Carbon Control) treatment aids outstanding rim braking performance in all conditions, rounding out this superb set of aerodynamic racing wheels. Included: - Special brake block kit for carbon wheels (red compound): 40% better braking performance in wet conditions and 20% better in dry. - Lightweight Quick Release wheels with an aerodynamic profile and shiny finish. - Tubeless valves with valve extenders - Bushing to reduce the size of the valve hole - 2 levers in composite material for tyre removal - User manual
This carbon road bike wheelset features a 60mm rim profile that is designed to appeal to cyclists who want greater speed and smoother performance. Its high profile can transfer all the aerodynamic advantages acquired from Campagnolo's research and development study 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. Engineered for disc brake compatibility, this race-ready model ensures that you can maintain your momentum and benefit from powerful braking when needed. 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 is determined by 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 28 mm 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, allows a weight saving, increased stiffness and now also an aid when using tubeless tyres: no tape is required. 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. BORA WTO 60 DB: made for winning in sprint finishes, circuit races, time trials and triathlons. Available versions: dark label, Campagnolo FW hub, HG or XDR. Included: - 44 mm tubeless valve - 40 mm valve extender - Bushing to reduce the size of the valve hole - 2 levers in composite material for tyre removal - User manual Technologies: Assembly: 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. USB Ultra-smooth Bearings: Guarantees extremely high smoothness. G3 Geometry: Reinvent the wheel, not just its look. 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 28 mm tyres, with perfect pairing of the rim-tyre system. Choose aero... but make it Campagnolo: The 60 mm 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 60 mm profile with a wheelset weight of 1,590 g makes it the perfect ally to win sprint finishes, circuit races, time trials and cycling sections in triathlons.
The Campagnolo Bora WTO 60 has been tested rigorously to allow for a new rim design that maximises aerodynamic penetration for those particularly sharp wind angles and downwind presses. With a hub that promotes airflow detachment and a spoke set-up (18-elliptical cross at front, 21-rear cross at rear) engineered to overcome rolling resistance, this is the perfect wheelset for those expecting to face tough conditions. Aerodynamic Road Wheels with Advanced Stopping Power With the implementation of AC3™ technology in the rim brake design of the Campagnolo Bora WTO 60 Wheelset, with years of research put into the durability and stopping power of the texture, you can be sure of a more reliable stop with this wheelset whether it's wet or dry. Included: - Special brake block kit for carbon wheels (red compound): 40% better braking performance in wet conditions and 20% better in dry - Lightweight Quick Release wheels with an aerodynamic profile and shiny finish - Tubeless valves with valve extenders - Bushing to reduce the size of the valve hole - 2 levers in composite material for tyre removal - User manual
The Campagnolo Calima C17 road wheels features the market leading Campagnolo technology and is ready for any adventure and for any challenge, race or endurance event you place in front of it. It features the Campagnolo iconic, performance-enhancing Mega-G3 spoke lacing pattern. This improves energy between the rider and the road, which reduces stresses on the drive side (right side) of the wheel while increasing the wheel's rigidity at the same time. This significant performance enhancement is achieved by the drive side of the rear wheels having twice as many spokes as the non-drive side (left side). Hand-Built Campagnolo wheels are hand-built entirely by specialist Campagnolo wheel builders and are fine-tuned and checked precisely with electronic tools. This ensures that this Campagnolo Calima C17 wheelset delivers the high-performance output that Campagnolo wheels are known for. Technologies: 24mm symmetrical profile rim creates a front wheel that is precise in directional changes and a rear wheel that is reactive to changes in pace C17 class rim to allow the fitting of wider (25-28mm) tyres for riding comfort Sealed Cartridge Bearings - for increased longevity Machined precise spoke seat for longer spoke life Black stainless steel spokes Mega-G3™ spoke pattern for the perfect balance of tension on both sides of the wheel Aluminium hub and steel axle for increased lateral stiffness Please Note: When choosing your option, the "Campagnolo" option will only work with Campagnolo 9-12-Speed road cassettes, and the "Shimano" option will only work with Shimano/SRAM 9-11-Speed road cassettes.

It's also very versatile, as if you want to change from a 50/34t to a 53/36t or vice-versa, there's no need to change the entire crankset as the spider is compatible with either chainring combination. Smooth Performance The Centaur's chainrings have a special anti-friction coating to encourage smooth chain operation. The chainrings also feature Campagnolo's "MPS™" technology, which enables quick and accurate shifts no matter how hard your pushing and in all weather conditions. Also, thanks to the use of the "Ultra Torque™" bottom bracket system, you'll enjoy consistent, rigid performance and optimised power transfer. Technologies: MPS™ (Micro Precision Shifting System): Optimised design of the up-shift and down-shift zones and of the profile of the teeth – enables fast and precise shifting in all types of conditions. 8 chain upshifting areas and 2 chain downshifting areas result in faster and more precise shifting, even under stress. Ultra Torque System™: Six years after its introduction, this system is still considered the best performing crankset spindle in terms of stiffness, low weight and efficiency of power transmission. Campagnolo found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals. Furthermore, despite the narrow side profile, Campagnolo has been able to position the bearings outside the bottom bracket shell, resulting in greater axle rigidity from the increased axle diameter.
Engineered to have an elegant and modern appearance, this stunning kit provides you with everything you need for fast shifting accuracy and unmatched disc braking performance. Furthermore, it is an ideal choice for riders who spend hours in the saddle across mixed terrain conditions while still maintaining the racing performance you would expect from Campagnolo.
