Description

The Radio Xenon Junior steps things up for riders ready to go faster, push harder, and get serious on the track. Built around a hydroformed 6061-T6 alloy frame with disc-ready dropouts, it’s light, stiff, and made to handle proper race pace. The full crmo fork keeps things solid up front.
Loaded with Radio Raceline Xenon parts, this thing is anything but entry-level—3pc cranks, sealed cassette hub, and a dialled drivetrain that delivers smooth, efficient power every lap. The Tioga Power Block tyres grip hard out of the gate, and the rear disc brake brings reliable stopping when it matters.

At just 7.78kg, it’s still crazy light for its size, making it perfect for riders progressing through the ranks without being held back. The Xenon Junior is built to go fast, stay smooth, and keep the good times rolling every session.
