Description
THE FIXER
True performance is never just numbers on paper – it is the perfect blend of function and feeling; the rider and bike coming together as one. This is the design ethos of the A40, dubbed ‘The Fixer’. With a new endurance geometry, additional mounting bosses for racks/mudguards/3rd bottle and true clearance for 700c x 40mm tires, the A40 takes you further into uncharted territories.
DESIGN DETAILS
The devil is in the details and in places where you don’t immediately see; new custom designed drop outs, headtube, flat mount brake bosses.
DRIVETRAIN VERSATILITY
The A40 supports all 1x and 2x mechanical road groupsets from 8 speed onward, thanks to a custom cable stop port—making it one of today’s most universally compatible bikes for drive trains.
WEIGHT OPTIMIZED
The A40’s new hydro-formed tubeset boosts comfort for all-day rides, retains beloved A30 handling, and features hidden weight-saving details, weighing 100g less than A30 frames.
