Red Zone™ has been created for riders who love using their mountain bike with no limits. We could define it as Enduro-Freeride, or if you prefer, a wheel that’s light & reactive for climbs & strong & resistant when you decide to lift the wheels off the ground. The rims are class 21 lightened between one spoke & the other, so we have a rim that is strong but at the same light. Both the front & rear wheels have 24 stainless steel spokes with variable thickness 2.2/1.8/2, with reinforced head, distributed according to Fulcrum® 2:1 technology with double the number of spokes on the cassette side for the rear wheel & disc side for the front. This means getting the maximum performance both when pedalling & manoeuvring. Red Zone™ is compatible with UST tubeless tyres & with all ISO six-bolt braking systems. Technologies: Ultrafit Tubeless: Imagine the rim & tyre as a single unit composed of two materials. This is what we wanted to achieve conceptually with Ultra-Fit™ Tubeless
