Geometry and Sizing
The frame is available in 5 sizes, including Extra-Medium (XM), specifically designed to cover the most common height range (between 5'5" and 6'0"). The geometry follows the "more travel, more stability" rule:
Oso HD: 63.1° head tube angle (extremely slack for steep terrain).
Oso TR: 64° head tube angle (a perfect balance of stability and reactivity).
Oso S: More conservative and snappy geometry to maximize speed on less aggressive trails.
