Campagnolo introduces the first aerodynamic disc brake wheel with a 45mm profile, designed to appeal to a broader customer base. The design of the rim enables maximum aerodynamic penetration, and at certain angles, the wind can actually become a valuable ally to the rider.
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.
Available versions: dark label, campagnolo freewheel hub, hg or xdr
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 unidirectional carbon rim delivers the rideability and rigidity that 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 designed for optimal rigidity and weight
**features & benefits**
**45mmâ but aero**
* the rim design enables the maximum amount of aerodynamic penetration when the wind angle is between 12â and 19â, making it a thrust for triathlon athletes
* 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 airflow detachment
* the 24-spoke elliptical cross section results in a far superior rolling resistance
**fast andâfluid**
* 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
**choose aero... But make it campagnolo**
* campagnolo's rideability is enhanced by the 45mm 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 45mm profile and a weight of 1,520g for the pair makes this wheel ideal for riding on hilly routes
