Black and gold Cobalt Diablo hardtail mountain bike overlooking an alpine lake

Mountain Bikes

Cobalt mountain bikes cover three distinct riding styles. Diablo is the lightweight carbon hardtail for efficient XC and fast trail riding. Hellbender adds full suspension for cross-country speed and control, while Thunderbolt brings 150 mm travel for more aggressive trail terrain.

Choose the platform around where and how you ride, then select a Core, Performance or Elite build and tailor the fit and components. This collection is for complete mountain bikes; Cobalt frame packages are kept separately in Framesets so it is easier to compare complete-bike options.
