Suspension for your hands. Our exclusive vibration-damping IsoZone material absorbs road bumps and buzz, giving you more control and an incredibly comfortable ride.

Tough Bontrager Hard-Case tyres help keep punctures from slowing you down.
Alpha Gold Aluminium frame
Our high-performance lightweight aluminium is continuously cold extruded and butted, and formed into manipulated tube shapes to balance strength and save weight.
