Every base is injected with nylon glass fibre which provides optimal weight and strength savings and is constructed with a dominate base bridge. This bridge allows for ultimate stiffness, resulting in superior power transfer with each pedal stroke. To combat the structural firmness, each Circuit incorporates a Light-Weight EVA foam.
The Circuit Mtn delivers relief through a hidden under-cut and is assembled with a dual panel, double stitched cover. With a durable microfibre material top and bulletproof Kevlar side panels, the Circuit Carbon delivers at all levels.
