Key Features


TREK Stache

Stache 9.7 is the lightest 29+ hardtail ever created by Trek, all credits to the OCLV Mountain Carbon frame.

The frame looks oversized, yet is shockingly lightweight and brings the bike to its full potential.

In the Trek product line, every model with “9.” in their name means that they feature carbon frame.

This particular trek hardtail runs on 3” x 29” tires with Boost spacing.

The right side of the frame features an elevated chainstay; this is so it can accommodate the huge, chunky wheels. And, such design also eliminates chain slap.

Chassis of Stache 9.7 is remarkably sturdy, to deliver precise handling and quick pedaling response.

Tapered E2 head tube and flowing frame tubes, allow for great torsional strength to easily direct this 29er wherever you’d like.

Shifter and dropper post has internal cable routing to give the bike a cleaner and uncluttered look.

​For better stability during fun rides, the bike is housed with an air-adjustable RockShox Pike RL suspension fork. The 15mm thru-axle delivers extra precision while handling, whereas 120mm travel and bulky 35mm stanchions make hard landings much more convenient.

Frame Specifications

For 17.5” frame size, Stache 9.7 comes with 611 mm effective top tube with a 416 mm reach and 635 mm stack.

Chainstays on this are 420 mm, whereas the wheelbase measures 1116 mm.

The bike has a maximum weight capacity of around 136 kg (300 lbs.), including the weight of the rider, cargo, and bike itself.

Wheel Design

Wheel Design

Trek makes sure to locate the wheel deep into the frame.

The rear of Stache 9.7 looks funky due to rear fork viz. “Midstay.”

Asymmetrically designed Midstay has the chain running on the underside of rear fork. This causes the bottom bracket to come nearer to the wheel. Such a unique design is aimed to make the Stache 9.7 more agile.

If you place the tire deeper into the frame, you will stay near to the mid-section of the bike, the chainstay and wheelbase get shorter, and your bike will be amazingly agile!

Unique Midstay features “Stranglehold dropout,” with which you can convert your Stache 9.7 into a single-speed bike whenever.


When it comes to maneuverability, Stache 9.7 outshines in every which way possible. It is enjoyable and easy to direct the bike, especially during street tricks.

It floats over the trail, while the 29+ tires give you excellent grip. Thereupon, letting you make high-speed turns.
