Description

LIGHTWEIGHT

Is there anything more wholesome than a kid having fun in the dirt? This is why we designed the new Xtrada 20” with the perfect mix of speed, confidence and durability—featuring ALX Jr. lightweight aluminium, Super low weight and aggressive tube angles.

GEOMETRY

The Xtradas' sporty angles, tapered headtube, and short chainstays make for safe riding and steady handling. Ideal for fire trails and single tracks, it features a 66° head tube and 75° seat tube angles, and 340mm chain stays for confident handling and happy young shredders.

MODERN DESIGN

Light, durable, and hydroformed, the 6061 aluminium frame features a threaded bottom bracket, internal cable routing, and the latest mod cons.

SUNTOUR XCM Jr.

The Xtrada comes equipped with 80mm air-sprung forks, which offer a smooth/controlled ride for newer riders and feature a lockout adjuster.

MICROSHIFT 9-SPEED

9-Speed Advent from Microshift offers a massive gear range, with a 30t chainring up front and an 11-38t on the rear. The rear derailleur also features a short cage to help keep it safe.

HYDRO DISCS

Tektro Jr. hydraulic brakes provide loads of power, modulation, and control. The Xtrada’s brakes feature levers designed for small hands that are easy to reach.
