Equipped with a tall 80mm rim, this carbon-fibre road wheel takes you through every triathlon stage and time trial with composure and strength. Stiff and easy-to-handle at high speeds, this tubeless-ready rim gives a lightweight and drag-reducing experience on every outing. Deep-Rimmed, High-Performance Carbon-Fibre Road Wheel Designed alongside aero-wheel specialists SWISS SIDE, this Dicut model rolls with superb control and speed thanks to its DT240 hub and SINC ceramic bearings. Laced with DT Aero Comp spokes for added strength and stiffness, the hub keeps the wheel as responsive as can be.

Specifically developed for the demands of modern road cycling, this tubular wheelset comes kitted out with two high-quality full carbon fibre rims for the best balance of stiffness, strength and low weight rotative performance. Campagnolo has also equipped this model with a 35mm profile, so you can benefit from guaranteed maximum lightness and aerodynamics as you put the power down. Designed for best results when riding uphill and on the flat, its lightweight CULT bearings offer up to nine times the smoothness of standard solutions. With its aerodynamic profile spokes providing maximum air penetration and its 6-bolt disc brake compatibility delivering powerful and consistent braking operation, this is a perfect choice for a wide range of riders. The Bora One 35 Disc brake is the perfect answer for cyclists searching for deep profiles capable of offering significant aerodynamic advantages while remaining lightweight and reactive for the steepest climbs. Its extremely sophisticated carbon fibre 24.2mm rim offers a rim and tyre interface optimised for the use of both 25 and 28mm tyres, by creating a more aerodynamic complete unit and a more efficient and sure-footed structure. Carbon Fibre Wheelset with CULT Bearings CULT Bearings (Ceramic Ultimate Level Technology) is a combination of the highest quality ceramic ball bearings and stainless-steel races available on the market, to reduce friction to the very minimum yet maintain a consistently high level of performance for long periods of time. The Mega-G3 Spoke pattern is a type of spoke assembly that improves energy transfer between the hub, which reduces stress on the right-hand side which in turn increases the rigidity of the wheel. This is achieved by having twice as many spokes as the left-hand side. 6-Bolt Disc Brake Compatibility The Bora One 35 Disc represents the same quality, performance and reliability that made its rim-brake predecessor such an iconic wheel. While it incorporates any technologies used in the rim brake version, this wheelset has been specifically designed for the unique demands that come with disc brake construction. The wheel has been engineered to optimise the distribution of forces caused by disc brakes. The Bora One 35 Disc Brake Wheel is entirely hand-built by a specialised Campagnolo technician and is checked in every tiny detail with electronic tools. This ensures that every wheel conforms to the high standards that Campagnolo pride itself and will have unbeatable reliability.
