It's right for you if...
Your attitude is that mountain biking should be, above all else, a ridiculous amount of fun. You want a base for your build that matches your fun-loving approach to the trail, with the versatility to run a full drivetrain or a single-speed setup.
The tech you get
A trail-tough Alpha Platinum Aluminium frameset with super-short chainstays that give you the ability to pop off jumps and toss the bike around corners. Stache AL Frameset includes Stranglehold Dropouts so you can fine-tune your geometry or run single-speed. It has internal derailleur and dropper post routing, includes a headset and is designed for disc brakes and Boost148 29+ wheels.
The final word
Stache AL Frameset is the first step to more fun on the trail. The short chainstays deliver a lively ride and quick acceleration. Build it up with 29+ mid-fat tyres for relentless traction.
favorite_borderWhy you'll love it
- 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
- We're not the only ones who love it: DirtRag says, '[Stache] is the most fun bike I rode this year, and fun is where it's at.'
- The Stranglehold adjustable thru axle lets you fine-tune the length of your chainstay
29+ is a wider 3" tyre that grips relentlessly while floating over terrain. Yet it delivers all the 29er benefits that you know and love, like greater momentum and improved rollover.
How do you fit a 29" tyre without elongating the wheelbase? Elevate the drive-side chainstay up and out of the way.
Alpha Platinum Aluminium
Our premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
Dropper post internal routing
Not ready for an internally routed dropper post now, but want to keep your options open? Select frames are equipped with the proper entry and exit points to accommodate internal routing for a Stealth seat post.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
