Trek Full Stache 8
Details
Full Stache 8 is a full suspension 29+ trail bike with an oversized appetite for rugged backcountry riding. Sure-footed mid-fat tires, a 1x12 drivetrain, 130mm of front and rear travel, super short chainstays, and some ridiculously clever engineering make this 29+ trail bike the ideal rig for rugged singletrack and trail explorations into the unknown wild.
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.
Why 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
Wider than standard yet narrower than fat, plus-size rims and tires hit the sweet spot in grip, stability, and speed, giving you more confidence on technical terrain. Compared to a standard tire you’ll feel grip in places you wouldn’t expect thanks to a bigger contact patch and greater rollover clearance. More air volume allows lower tire pressures which softens bumps and increases float on sand or snow. Whether you’re a novice or an expert, the benefits of plus-size tires and rims will amplify your mountain biking fun.
A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.
Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.
Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
