Fans of 29+ rejoice, Trek sees you. After a surprising amount of success with the original Trek Stache 29+ hardtail, Trek is back with something a bit more plush. The new Full Stache could be just what you’re looking for – if that’s a burly 130mm travel trail bike with massive tires to get you out into the backcountry.
Obviously, when it comes to the Full Stache, it’s all about the wheels and tires. Built specifically around 29+, Bontrager even came up with a new XR4 29 x 3.0″ tire for the build. 29+ is like a 29er on steroids, with even better roll over abilities and a substantially larger contact patch for improved traction. But all that rubber requires special considerations for the build.
In order to fit the wheels and tires in the frame while still keeping super short 430mm chainstays, Trek opted for a raised driveside chainstay design – sort of like the original. They also rotated the main pivot forward in front of the bottom bracket. Note that this does limit you to a 32t chainring, but with these massive wheels and tires that probably won’t be an issue.
That allows for 130mm of travel out of the RE:aktiv Fox Float shock, even with the monster tires. 130mm of travel puts it on par with the Lenz Behemoth 29+ (in the 5″ travel version), but the Full Stache edges the Lenz out in the chainstay department by 5mm.
Offered in only one Alpha Platinum Aluminum frame configuration, the frame features many of Trek’s technologies like ABP, Knock Block Steerer Stop, a Mino Link geometry chip, Control Freak internal housing, and G2 geomtry. Naturally, the frame is Boost 148 with a tapered head tube, post mount, and it runs a PF92 bottom bracket.
With the Mino Link adjustment, the High/Steep setting runs a 67.4° head tube angle and 343mm bottom braket, while the Low/Slack setting switches to 67° at the head tube angle and 338mm for the bottom bracket. The bike comes stock with a 130mm travel suspension fork, but it has been tested with a 140mm travel fork as well if you want to slack it out even further.
Offered in one complete build for $3,699, or as a frame only for $1,999, claimed weight for the complete build is claimed as 33.88lbs/15.36kg with tubes. Sold in 17.5 19.5, and 21.5″ sizes, Full Stache is available now for your big tire enjoyment.
