# Trek Stache AL Frameset

Stache AL Frameset is built with our lightweight and trail-tough Alpha Platinum Aluminum. This trail hardtail frameset is designed for fun-loving 29+ tires, with massive tire clearance, an elevated midstay, and horizontal sliding dropouts that make it easy to fine-tune your geometry or turn it into a singlespeed mountain bike.

-   You get an awesome alloy frame, and can spend the money you saved on killer parts
-   Stache is super versatile and equally at home on multi-day bikepacking trips as it is on rough singletrack
-   The super-short chainstays make it really easy to show off your wheelie skills

  

### Advanced frame tech

Stache is surprisingly nimble thanks to extra-short 420mm chainstays. The elevated mid-stay makes room for the extra-big tires while Horizontal Sliding Dropouts allow you to fine-tune your wheelbase length.

### 29+

29+ is a wider 3" tire that grips relentlessly while floating over terrain. Yet it delivers all the 29er benefits you know and love, like greater momentum and improved rollover.
