MOULTON

XTB

Moulton XTB bicycle in steely grey with SRAM Rival 11-speed drivetrain, front angle view

XTB

£4,715.00

The Moulton XTB is the contemporary cross-terrain interpretation of the original AM-ATB, widely recognised as the world’s first production full-suspension mountain bike. Designed for gravel, forest tracks and mixed-surface riding, it builds upon the hairpin spaceframe with reinforced bracing, dual rear fork uprights and uprated suspension. Stronger, lighter and more purpose-specific than its predecessor, the XTB brings Moulton engineering into rougher terrain while retaining separability, load-carrying capability and the unmistakable ride composure that defines every Moulton.
