At first sight they might look like road wheels...but they are not!
The main and actual difference, apart from "CX" following "Racing 7", lies inside the new hub with a double gasket to protect bearings from dust and mud, guaranteeing the smoothness and long life of components.
The new double-coating hubs were designed for straight spokes: aluminum made and with a large flange on the driveside of the rear wheel, markedly increasing reaction.
The front wheel has 20 steel spokes with 2mm round section. The spokes of the rear wheel have a 2:1 ratio. Two-to-OneTM: 8 2mm round spokes, radially laced for the left side; while on the driveside there are twice as many straight spokes, with the same 2mm section.
In order to control wear in Racing 7CXs, Fulcrum has included the new Wear indicator system.
Racing 5 CXs are compatible with Campagnolo, Shimano Inc. and Sram Co. transmissions. Nominal weight*: front: 828 gr rear: 1021 gr
