Summary

The Trek Stache is a cross-country hardtail with 29+ tires that deliver incredible traction and a smooth ride over rough terrain. Its geometry is playful and agile, making it fun and confidence-inspiring on the trail. However, it can be expensive and the tires are prone to damage in rocky conditions.

Pros
  • Huge amounts of traction from 29+ tires

  • Playful and agile geometry

  • Versatile with adjustable chainstays and wheel options

Cons
  • Expensive frame and components

  • Tyres are easily damaged in rocky terrain

  • No dropper post on some builds

Key Quotes
The result is a similar ground smoothing low pressure footprint to a 27.5in plus-tyre, but amplified in terms of bump shrinking speed sustained by the shallower contact angle of the 29in diameter
BikeRadar logoBikeRadar
The Stache’s strengths include insane levels of traction and a geometry aimed at being able to throw those big hoops around at will.
Flow Mountain Bike logoFlow Mountain Bike
It’s no buzz kill, though, and the safety net of the Velcro-like traction means you can chuck the Stache around the trail with reckless abandon, and this makes it seriously good fun to ride.

Trek Stache 29+ Retrial

Aug 2017

A few changes have altered Andrew's impression of the task so dramatically that a new review was in order...

Highs
  • Upgradeable frame

  • Improved performance with fork upgrade

  • Fast descending hardtail

  • Smooth suspension with Mattoc Pro

  • Good climbing traction with long rear center

  • Faultless 11spd SRAM GX drivetrain

  • Forgiving ride due to frame and 3" rear tire

Lows
  • Stock Chupacabra tires are weak for aggressive riding

  • SRAM Level brakes feel under-gunned

  • Seat stays occasionally bite

  • Would prefer straighter seat tube on custom frame

Trek Stache 9.8 Review – An Unusual 29 Plus Hardtail on Test

Mar 2017 · Christoph Bayer

The Trek Stache 9.8 doesn't fit into established categories. With its huge 29" plus size wheels it attracts all the attention, but how does it ride?

Flow's First Bite: Trek Stache 7

Nov 2016

As we’ve learned over the past few weeks, however, first impressions aren’t everything, but we certainly have done a lot of laughing whilst riding this thing, it’s a whole lot of fun! Ahead of our review, here is a little preview of this very unique bike. Oh, and does anyone know what a Chupacabra actually …

Highs
  • Huge amounts of traction from the 29+ tyres.

  • Stranglehold dropout allows for 29+, 29" or 27.5+ wheels.

  • Geometry is fun and lively.

Lows
  • Manitou fork axle is very fiddly.

  • No dropper post.

Tested: Trek Stache 9 29+

Jun 2016

Call it what you want — tweeners, plus size, midfat, skinny fat — plus size bikes are here and the industry is latching on, for better or for worse. By mid-summer 2016, you can expect to see a 27.5+ bike in the wheelhouse of every major bike brand. However, 29.5+ is far less common, with Trek Bikes being one of the only major brands to adopt these extra tall, extra wide crawlers.
