It's right for you if...
You believe mountain biking isn't about racing or showing off. It's about the experience of being out there in the rough, wonderful wild. For you, every ride is both a battle against nature and an appreciation of it. There's a whole lot of beauty in dirt, rocks, and roots. Trails don't need to be perfectly sculpted to be enjoyed.
The tech you get
An Alpha Platinum Aluminum frame with 130mm of travel, a Straight Shot down tube for extra stiffness in the rough, and a Knock Block steerer stop to protect against spinning bars. A SRAM GX Eagle 1x12 drivetrain with a huge gear range, a FOX Float rear shock with Trek's exclusive RE:aktiv damper, a 130mm RockShox Pike Select Plus fork with a plush DebonAir spring and Charger 2 RC damper that gives you more adjustment and control. Plus, aggressive 29x3.0˝ Bontrager XR4 Tubeless Ready mid-fat tires on beefy 40mm rims, and a Bontrager dropper post.
The final word
This is a new breed of performance backcountry trail bike. If you love seeking out the untamed trails in the wild and discovering new lines while ripping bikepacking adventures, Full Stache 8 is your dream ride. It's like that one friend who's always egging you on to go a little farther, because there's bound to be something epic right over the next ridge or at the bottom of the next valley.
favorite_borderWhy you'll love it
- This bike was born for adventure in the wild outback, where capability isn't just something that's nice to have but an absolute essential
- Mid-fat tires are sure-footed on technical singletrack, tricky descents, and whatever trail you'll find where other riders dare not roam
- The shifter-style, underbar remote dropper post lever is super intuitive and easy to use
- 29x3.0˝ tires give you the flotation of a fat bike with the speed and momentum of a fast-rolling 29er
- Super short chainstays make Full Stache surprisingly agile, even with its 29+ wheels

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
