Fulcrum Red Zone XLR MTB Wheelset Compatibility and Specifications

Fulcrum Red Zone MTB Tubeless disc brake wheelset 2011.

Fulcrum is a Campagnolo brand.

Red Zone™ XLR is the boldest version of the Red Zone™ model.
It’s an absolutely multipurpose model that could be defined as Enduro-Freeride.

The aluminium rims are specially milled for lightening between the anchoring points of the spokes to obtain a rim that’s extremely resistant to impact yet also very light.
The aluminium spokes are designed and produced by Fulcrum® to ensure the maximum performance in every moment
and in every situation.
Both the front and rear wheels have 24 spokes, distributed according to the exclusive Fulcrum® 2:1 spoke ratio, which significantly increases your power transmission and your manoeuvring precision.
Red Zone™ XLR wheels are compatible with tubeless tires, which adhere perfectly thanks to the Ultra-Fit™ Tubeless system, eliminating energy dispersion to the advantage of speed and therefore of overall performance.

Red Zone XLR includes the 142mm SYNTACE X-12 ADAPTER KIT (only suitable for 12mm through-bolt version).

Red Zone™ XLR is compatible with all ISO six-bolt braking systems.
