The Cobalt line combines proven geometry and dialled components giving you the best start out of the gate during the first days racing. The Cobalt Expert steps up to a 19.5″ top tube, a longer 50mm reach cobalt stem, a slim radio pivotal seat and wider 1 3/8 Arisun XLR8 tyres. All Cobalt bikes feature fully sealed front hubs and integrated headsets, making them simply unstoppale when comparing price to spec.
