17.5"TT Cobalt Mini 20
The cobalt line combines proven geometry and dialled components giving you the best start out of the gate during your first days racing. The cobalt mini is our pint-sized machine, the scaled down frame and lighter build kit make this thing unrivalled out there on the track.
Fresh out of the box for 2021 with incredible new paint and graphics, you’ll be able to spot a cobalt on the track very easily. All cobalt bikes now feature full sealed front hubs and integrated headsets, making them simply unbeatable when comparing price to spec. The cobalt is one seriously unstoppable machine.
