LIGHTWEIGHT TRAIL-READY MTB
The all-new Xtrada opens the door to XC and trail riding with handling that feels sure-footed yet responsive on singletrack and trails. Its ALX butted aluminium frame uses precision-formed tubes to keep weight low and strength high, with sleek internal routing and extra standover clearance for added confidence over uneven ground.
MODERN XC GEOMETRY
A slightly slacker head angle steadies steering on descents and loose gravel, while short chainstays keep cornering responsive. A balanced, upright position supports comfortable climbing and smooth pedalling, and 29-inch wheels help carry speed over roots and rocks, maintaining control as trail conditions vary.
DEPENDABLE COMPONENTS
A 120 mm suspension fork increases grip and comfort through rougher trail sections and offers lockout for efficient climbing. A durable 1× Shimano drivetrain provides wide-range gearing, and the clutch-equipped derailleur reduces chain slap to keep things quiet on rough terrain. The included dropper post lets riders get the saddle out of the way for added control on descents.
X-FUSION MIGO LO32 FORK
120 mm air-spring fork with lockout and rebound tuning. Air pressure can be tuned to suit rider weight and riding style, while 32 mm stanchions, tapered steerer and Boost 15×110 axle improve stiffness and steering precision.
DEORE 12-SPEED DRIVETRAIN
HyperGlide+ shift ramps enable under-load shifting with a 10–51T cassette on Micro-Spline freehub. Durable steel sprockets optimise longevity and value for trail riding.
SHIMANO MT200 HYDRAULIC BRAKES
Two-piston hydraulic system delivers consistent modulation and fade resistance. Mineral oil and a closed hydraulic layout minimise maintenance and improve lever feel compared to mechanical discs.
X-FUSION MANIC DROPPER POST
Internal dropper lets you lower the saddle at the press of a lever, getting it out of the way for descents and obstacles to increase manoeuvrability and confidence, then raise it instantly for climbing.
BOOST AXLES & UDH
Boost 15×110 / 12×148 hub spacing increases wheel stiffness and tyre clearance for more precise handling. The Universal Derailleur Hanger standard protects drivetrain alignment from impacts and makes hanger replacement simple and widely compatible.

Buy One, Plant One
Since January 2020 we have worked with not-for-profit reforestation partners to donate enough money to pay a local person a fair wage to grow, plant and guard to maturity 1 native tree for every bike we sell.
We've now planted more than 400,000 trees and counting!
