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 Expert steps up to a 19.5″ toptube, a longer 50mm reach cobalt stem, a slim Radio combo seat and wider 1 3/8″ ARISUN "XLR8" tires.
Fresh out of the box this year 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.
