Review: Trek Stache 8 – Rally 29er Hardtail

29er All Mountain Trail

The Ride
The bike has a stiff bottom bracket area and the wheel is tucked underneath the rider with shortish stays of 17.5 inches. While not leading edge short for a hardtail, this translates to an agile and responsive climber. Some say that 29ers accelerate slow. This does not as it will scoot forward when you spin, mash or pounce on the pedals. It achieves good traction with with the capable Bontrager 29-3 tires when running low pressure. It is still a hardtail so rocky and climbs have to be tackled with finesse as there is no rear suspension conforming with the trail for traction. Achieving the minimum air pressure on the rear tire is key for getting traction and minimizing getting bounced around on tech climbs.

When it comes to handling and quickness the G2 geometry, lateral stiffness and 142 mm rear thru axle deliver a bike that likes to carve. We are not certain what the 142 mm rear axle contributes to an already stiff hardtail but this blend of G2 geometry, slack head angle and shortish stays blend together to create an agile and balanced bike.

Jumps and Drops
Ok, this is where the fun begins as this bike loves to play. It is like a trail dog that like to run all over the forest, jump over rocks and splash through the water. This is the greatest asset of this bike and it is a great revelation since this not the assumed habitat of the hardtail 29er. We all know that the peers of this bike are taking over the XC racing circuit and winning races both of the short and endurance variety. But to actually hoot and holler while riding an all mountain trail on a hardtail 29er is somewhat new ground.

We rode this bike without a dropper post for a couple of weeks and were impressed. But then we put a KS Lev on it and the bike’s attitude transformed along with ours. All of a sudden, this 29er hardtail felt a little bit like the 650b all mountain bikes we’ve been riding lately. The riding position and wheel base now felt similar. Of course there was no travel in the rear so letting the brakes go on a rock garden was not a good idea. But every berm, every undulation and tree root jump looked like a target for this eager trail dog to pounce on. This bike felt like a dirt jump bike for the forest.

We believe that in five years, most bikes, even hardtails will have a dropper post. But we’re not quite ready for that paradigm shift as none of our hardtail steeds sport one. But this bike has expedited our exodus from the world of rigid posts. The dropper post completely transformed the Trek Stache in to a trail bike. And the the Stache was ready for it with its wide bars, slack head angle and playful geometry. The stock 90 mm stem had to go of course for a 60mm but everything else was dialed.

The Stache 8 is drop dead gorgeous if you like the lime green theme. That frame itself is a nude-bronze polish with green graphics. This green theme is then carried on to the seatpost hardware, seat, rims, fork headset spacers and grips. Everything is just a hint of the theme until you get to the centerpiece lime green Race Face cranks.Then the bike is finished off with internal cable routing throughout. And the leading edge idea here is the built-in internal Sram Reverb Stealth cable routing. In the end we don’t think many folks will use the Reverb Stealth routing since that requires bleeding the cable to install this specific dropper post. But it is a bold statement to say that this hardtail was designed for a dropper post.

    It may be a great bike but it has NOT got short chainstays!! At 17.5″ they are nowhere near true trail/am 29ers like KOna Honzo, Canfield Yelli Screamy/Nimble 9 etc.

  • Tom says:

    Great review. Thank goodness it has normal, or slightly short chainstays for balanced handling!

    The Ride

  • Bill Duke says:

    Actually, the article very clearly states the stays are 17.5 inches on page 2. Some people just didn’t read the article.

    I have an 8 with a stealth reverb lefty remote, RF atlas bar that matches crank, tubeless setup and saint pedals mated to 5-10s….never thought I’d ride a hardtail again but DAMN….what a fun bike. And those new clutch derailleurs are the bees knees! So quiet thru the rough w/ no chainslap… don’t get a crappy spec entry level full sus bike til you ride this sled or something similar….too much fun on the downs and climbs with authority!

  • Stamps says:

    I’ve got an 8 spec’d w/ a stealth reverb, 50mm stem, RF atlas bar, tubeless and some saint pedals mated to some 5-10s…the bike is crazy fun.

    I’ve got a stable with a bike for just about every sub genre of mtb and the stache has been getting the most love lately for my local trails in the piedmont region of north carolina. Definitely worth a test ride if you’re in the market for high end hardtail or entry level full sus and like to shred hard…

  • Larry says:

    Trying to decide, purpose-wise, which bike would be better for me…Superfly AL Elite hardtail or Stache 8. I see some of the differences on paper, but both bikes are at a similar price point and look to appeal to a similar audience. Anyone care to offer some clarity?

  • Patrick says:

    If I had a 26er that had that long of chainstays and that much bb drop (yes I know 29ers are just going to have more…) I would say it handled lazily and the front end was hard to get up BUT because it’s a 29er it now has magic powers to defy its geo and is suddenly “playful”. Like others have said, no thanks… I’ll look towards a honzo or nimle nine for this category of bike.

  • pepelepau says:

    Dropper on a hardtail, is like putting road tires on a spesh DEMO. Makes no sense.

  • Marvin Gaye says:

    Two words: el mariachi.
    I generally like FC’s reviews, but this isn’t one of them.

  • roofus says:

    I have owned A Lot of bikes and ridden even more. I got a Stache 8 frameset prior to release and wasn’t going to put ANY $ into the build because I was a bit “unsure” of the claims With old worn out parts THIS BIKE RIPS! Nimble, fast, and begs to be pushed. Climbing, check, jumping, wait I hate to jump, to bad this bike floats. No one has ever ridden this bike and not come back smiling. And isn’t THAT what its all about.

  • Dontcoast says:

    This bike is super fun and way different than other g2 29erz.
    I was sceptical at first too but it won me over.

  • Eric says:

    Bike looks like a nice addition to the AM 29er HT lineup, but sounds like it’s missing a little compared to the others (Banshee Paradox, Canfield Yelli, Kona Honzo). Nobody is talking about the Titus Fireline Evo here. Sad they aren’t in AZ anymore but I just got a frame for 700 bucks (special edition). On a 120 mm fork h/t is 67.7. I put a 100 mm on and used a zero stack bottom headset cup to steepen the h/t angle. Maybe it’s 68.5 now? Either way, it’s a ti hardtail with slack h/t and shorter (17.1?) chainstays. For a sick, sick price. Fastest and most fun bike I’ve ridden. That said, the Stache or other more AM designed 29er HTs are a great place to be these days. Went from three bikes to one. If you’re thinking about getting a bike in this class please do. You’ll love it.

  • stamps says:

    Man, lotta people drinkin the hater-aid in the comments talkin bout geo and chainstay length. Im guessing most of these armchair commenters haven’t even test rode the bike.
    Full disclosure, I work at a trek dealer and I own a stache 8. The bike is one you should put on list for a test ride if you’re in the market for a quality hardtail. The bike has all the latest tech such as thru axles, tapered headtube, routing for a dropper, tubeless ready wheelset, shadow plus der. Etc…its good value for the $. I’ve got many bikes in the stable…a sc tallboy, intense ss, sc heckler, spech demo….and i’m going to this bike a lot.

    All this talk about xcal similarities is rubbish…the bikes are completely different rides designed for different uses. They feel completely differnt out on the trail. Sure there are great options out there like the honzo, canfield etc but let a bunch of spec numbers make the call for you. Test ride the bikes and get an informed opinion.

    this reply is coming from someone that has been totally anti-29er’s…. this is because I have ridden a few,,, HT and FS and never really had the thrash feel that I like…… however, after riding one that was lent to me I totally fell in love with it, the accelaration is immense, then it goes like a train,,,,, My local haunt is Harleston Firs, Northants and Woburn in Bucks, they have some really really tight tecky single track, but it turns through the trees and eats the trail up with such a speed that my 26″ wheel friends now having to try seriously hard to keep with me.
    Great frame, breaks, float forks,,, and even the finishing kit is good… 26.4lbs too….
    Bought mine from Ian at Leisura Lakes Daventry……
    Ian, if you read this mate, get out from infront of me mate, your slowing me down ;-)

    Since picking up my new Stache 8 last weekend, I’ve put 24 miles of single track on it. Coming from a 26er, I didn’t entirely know what to expect. The build quality and components are very good, and the bike looks awesome – but that never provides the whole story to a prospective buyer. So, as promised, I’m providing you some notes from my first couple of rides. Feel free to share.

    Setting off, I quickly noticed the difference in wheel/tire size, finding myself steering the bike more than I would my Cannondale. Some of this I attribute to the wider handlebars but there is a purposeful style in the bike’s geometry. What it may lack in ‘twitchy’ (a trait I came to love on my 26er), the Stache makes up for by stabilizing the trail. Meaning, you can keep more momentum going in, through and over things. It’s fast and deceivingly maneuverable. In fact, by the second ride, I was making checkpoints in shorter time than I have on my 26er. The Fox fork does a fantastic job to further smooth things out; I used all three settings but kept it on ‘trail’ for 90% of the rides. The clutch on the rear derailleur is brilliant, taking chain slap out of the rider’s experience. The Stach 8 is confidence-inspiring on the downhills, which brings me to introduce my new best friends, the SLX brakes. As a 6’1″, 200 lb proponent of going fast, I’m grateful for good brakes and found myself literally riding with an index finger on each lever.

    I didn’t demo a Stache 7 but I’d imagine the ride is very similar. I choose the Stache 8 because of the upgraded brakes and fork. Those items may not be worth the additional funds to everyone but they are to me. We’re still getting to know one-another but I’m pretty sure I’m going to love this bike. In my opinion, it’s perfect for the single-track fan who continues to embrace a hard-tail MTB.

  • Steve says:

    Hi, how is this bike on casual roads. Since I will be riding a lot around my subarbun neighborhood and small parks? Does it hold up well, too tiring?

    • Eddie Campbell says:

      Rides great on road,kind of feels big on the road compared to off road. Loads of fun,gets me over my head a little but then I’m a little hold backish(can’t work if I crash,factory worker)

    • don says:

      A road bike is better for roads. A mountain bike is better for mountains. Hopefully this makes sense.

  • d.peper says:

    This is a nice bike however I’d be more inclined to go Transition TransAm 29er. It has everything mentioned in the review in spades. At the mid $2k mark you got slack, steel, 120mm Fox, reverb, and the DOG! Plus very few components are house branded POS. Just a thought….

  • tom says:

    I purchased the Trek Stache 8 in 2013 made some minor changes graphite bars and seat post replaced Bontrager wheels with a set of Mavic SLR 29er wheelset with Mavic crossmax tires and this is a pretty quick bike with attitude.

  • MTB Mikey says:

    WOW! hateville is alive. I read every review and magazine and article I can find on my hobby because I love it. Read and do the math all you want couch engineers. I bought the Stache…it is f…… amazing to ride. That’s all, see you on the trails if you can catch me.
