Radio Xenon Expert XL Disc 20 Inch Bike

The Radio Xenon Expert Bike is built for riders stepping up their race game, combining lightweight alloy construction with pro-level components for serious speed. The hydroformed frame and chromoly fork keep things stiff and responsive, while the longer 20.5” top tube delivers added stability through high-speed sections.

A race-tuned drivetrain with a 41T sprocket, sealed cassette hub, and 170mm cranks ensures strong, efficient power delivery, while Tioga Power Block tyres maximise grip and roll. Finished with a rear disc brake and a wider, more aggressive cockpit, the Xenon Expert is dialled for control, confidence, and pushing harder every lap.
