Campagnolo Bora WTO 33 Disc 2-Way Tubeless Clincher Wheelset

Campagnolo introduces the first aerodynamic Disc Brake wheel with a 33mm profile. Each component of this wheel has been optimised in the wind tunnel in order to improve its aerodynamic performance. It therefore delivers multiple benefits that can be noted on different routes, from the most demanding of sprints to relaunching after a bend, while still ensuring efficiency on the flat and now also suitable for the hardest uphill finishes! It is a turning point in the all-rounder segment: a truly multi-purpose wheel.

The wheel features carbon rims with a unidirectional aerodynamic finish, new aerodynamic aluminium hubs, and the ceramic USB cup-and-cone bearing system: every design choice has been made with a view to optimising performance. The profile of the rim, which has an internal diameter of 19mm, corresponds perfectly with 23mm, 25mm and 28mm tyres. In addition, with the 2-Way Fit version, Campagnolo offers its tried-and-tested technology with full compatibility with clincher and tubeless tyres. While the key purpose of these wheels is to deliver extreme performance, safety is also guaranteed thanks to the G3 spoking system with double spokes on the left of the front wheel, to ensure balanced and safe braking in all conditions.

Main Benefits

33mm... But Aero

• The streamlined design of the central part of the hub decreases the frontal area of the component whilst the special design of the flanges favours the shut-off of the flow of air, thus reducing turbulence
• The 24-spoke elliptical cross section results in a far superior rolling resistance

Fast... And Fluid

• The well-known USB cup-and-cone bearing system guarantees smoothness in the ceramic bearings
• The 2-Way Fit profile allows you to mount either a clincher tyre or a tyre which offers the least rolling resistance possible: the tubeless tyre
• The 19mm inner diameter enables you to mount 23, 25 and 28mm tyres, with perfect pairing of the rim-tyre system

The Choice Of Campagnolo

• Campagnolo's rideability is enhanced by the 33mm profile, despite the aerodynamic design of the rim
• The wheel structure enables reducing energy dissipation, transferring all the energy produced by the cyclist to the asphalt
• A 33mm profile and a weight of 1485g for the pair makes this wheel ideal for even the most demanding routes

Technology

USB Ultra Smooth Bearings

Perfectly smooth surfaces and lower friction to reduce loss of power are the most interesting features.

Add on the reduced weight and resistance to corrosion and you will understand why Campagnolo can give you the best thanks to USB. All your power will be transferred onto the road.

Campagnolo has a long-standing reputation for the extremely high performance of its hubs in terms of smoothness and reliability. In fact, all the projects are entirely developed in our R&D department Campy Tech Lab and Campagnolo have put obsessive care into taking care of every detail.

The hubs with USB ceramic bearings (Ultra Smooth Bearings) further enhance the wheels' smoothness and reduce weight and the need for maintenance. Comparative tests have shown that USB bearings are 50% smoother than standard bearings.

Now improving your performance during the race or simply going for a ride with your friends will be easier.

USB - Ultra Smooth Bearings - technology is used for Record cranksets and for the new Shamal Ultra wheels.

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 equalising the load. Energy transfer and lateral rigidity are improved, and spoke tension is optimised, reducing stress and increasing lifespan.

All Campagnolo disc brake wheels utilise the G3 pattern, the front wheel has more spokes on the disc brake side, and the rear is biased to the drivetrain side.

Features

Wheel Developed In The Wind Tunnel

Every wheel component, from the rim to the hub and the spokes, is designed to guarantee maximum aerodynamic penetration.

Rim Made Entirely Of High Modulus Carbon

The rim made of unidirectional carbon ensures the ride-ability Campagnolo is known for.

Cup-and-cone Bearing System

Easy to register balls/bearings - reduced possibility of ball/bearing play - precise cycling operations - steady performance levels.

Hub Structure In Lightweight aluminium That Is Extremely Stiff And Aerodynamic

Optimised in the wind tunnel and yet designed for superb weight and stiffness performance.
