Yeti SB165 MX Series

The mullet configuration—a 29-inch front wheel paired with a 27.5-inch rear—gives you the best of both worlds. The larger front wheel rolls over obstacles and maintains stability at speed, while the smaller rear wheel makes the bike significantly easier to maneuver through tight, technical corners and flick around on jumps.

While the SB165 is built primarily for gravity and enduro riding, the steep seat tube angle puts you in an efficient climbing position. It isn't a cross-country bike, but it is surprisingly capable on the climbs, especially considering its long-travel suspension.

The suspension leverage curve is specifically tuned to work with coil shocks, which offer superior small-bump sensitivity and consistent performance on long, rough descents. This setup provides a planted, 'glued-to-the-ground' feel that air shocks sometimes struggle to replicate.

This bike is designed for aggressive riding on steep, technical terrain, bike parks, and jump-heavy trails. If you prioritize descending performance, big hits, and challenging features, this is the environment where the SB165 truly shines.

The Switch Infinity system is a robust, sealed mechanism that requires minimal maintenance compared to traditional pivot bearings. It is designed to be durable, though you should follow the manufacturer's recommended service intervals to keep the sliding rail clean and functioning smoothly.

Yes, the wheels are tubeless-ready. We recommend setting them up tubeless before your first ride to take full advantage of the traction benefits and to reduce the risk of pinch flats on rocky terrain.
