It's right for you if...
You ride because riding is fun, and you don't want to fuss with a full-suspension rig. You prioritize solid, dependable parts over the latest high-priced gadget, and want a bike you can take anywhere, from gravel bikepacking adventures to marathon singletrack days to gnarly, rocky routes.
The tech you get
An Alpha Platinum Aluminum frame with innovative features like an elevated midstay, Stranglehold dropouts, and Boost hub spacing for tons of tire clearance. The wide 3˝ tires mounted to 50mm SUNringlé rims deliver unbelievable traction, but are still spry enough to pop off jumps and scramble up climbs. Plus, it has a Shimano Deore 1x10 drivetrain with hydraulic disc brakes, a Manitou Machete 32 Comp fork with 120mm of travel, and a dropper post.
The final word
Stache 5 is an absolute blast. The short chainstays deliver a lively ride and quick acceleration, while the mid-fat tires grip loose terrain relentlessly and steamroll over obstacles. It's built with solid components that will hold up for all the good times on the trail.

"Heaps of tail-out hooliganism"
"Remember that friend you had in college? The big dude who dwarfed the rest of you in height and weight but could still keep up and was always the life of the party? That’s pretty much the Stache 9 in a nutshell."

"Its 29 Plus wheels offer a distinct ride experience, and the geometry keeps the ride closer to a trophy truck than a monster truck. Stache is the most fun bike I rode this year, and fun is where it's at. "

29+
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.
Mid-stay
How do you fit a 29" tyre without elongating the wheelbase? Elevate the drive-side chainstay up and out of the way.
Boost148/110
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 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.
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.
Internal derailleur routing
Sleek ports at the head tube and near the seat tube let you route your derailleur cables through the frame to keep your bike running smooth and clean.
Alpha Platinum Aluminum
Our premium lightweight aluminum is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
Stranglehold dropout
Horizontal sliding dropout with redundant securing mechanisms allows for no-slip singlespeed or geared options and provides the ability to dial in the geometry to match each rider’s style.
