SMOOTH WELDING

SMOOTH WELDING

Linear, precise, technical – the uniform aesthetic is flawless.

BRAKING SYSTEM

BRAKING SYSTEM

Post-mount disc brakes come standard on the A1r Disc – providing maximum power for shortened stopping distances, and ease of maintenance. The frame uses standard quick-release axles, and the width of rear hub is 135mm.

BOTTOM BRACKET

BOTTOM BRACKET

Bottom bracket bearings are installed directly into the frame. Thanks to this system, the bottom bracket shell is wider, and can consequently change the design of the down tube – making it wider and stiffer. It also adds to ease of maintenance.
