All of you die-hard alloy fans can rejoice. Yes, the new Stumpjumper ST comes in an alloy version, and it may be the most radically designed alloy bike ever made. And with new tube shapes and an asymmetrical design, the Stumpjumper ST Alloy 29 is sure to exceed your expectations of how a trail bike should ride.

- The all-new alloy Stumpjumper ST frame features an M5 alloy front- and rear-end, an asymmetrical design, and our 29 Trail Geometry, so it's both capable and comfortable
- The X-Fusion Metric rear shock features rebound adjustment, lockout, and our coveted Rx Trail Tune to ensure you're getting the most out of your Stumpjumper ST
- A RockShox Recon RL provides 130mm of travel up front, and it lets you adjust both rebound and lockout
