Radio Cobalt Junior
The Cobalt line combines proven geometry and dialed components, giving you the best start out of the gate during your first days racing. The Cobalt Junior steps up in size without packing on the pounds. At only 8kg, this is one of the lightest junior entry-level bikes out there.
Fresh out of the box with incredible new paint and graphics, you'll be able to spot a Cobalt on the track very easily. All Cobalt bikes now feature fully sealed front hubs and integrated headsets, making them simply unbeatable when comparing price to spec. The Cobalt is one seriously unstoppable machine.
