While I want to totally love and embrace this bike, I just can’t. When it came to stupid-steep, borderline unsustainable loose-over-hardpack climbs at Fort Ord, the only hiccup in the system was my fitness and not rear tire traction. The “trail” category is also climbing-conscious, and the epic traction of the plus-sized tires shines again. Aside from the Surly Instigator I think this may be the most aggressive non-standard mountain bike that I’ve ridden, and coupling the incredible plus-tire traction with aggressive geometry is a match made in heaven! My only question is: why doesn’t this rig have rear suspension?! Photo: Aaron ChamberlainĪs you could expect, the traction through sand, on the climbs, and in the corners was excellent thanks to the plus-sized tires. Thanks to the slack head tube angle the descending was confident and stable, and the cornering was aggressive thanks in part to the addition of a dropper post. Seriously, just smack the pedals and wrench the bars and that front end flies off the ground!Īlso, I found the actual on trail handling to reflect this as well. I got this rig out for a real-world test at the Sea Otter Classic, and the assertion by Trek that this is a “trail hardtail” is spot on! Despite the plus-sized 29″ tires this may be the easiest-to-wheelie bike that I’ve ever ridden, thanks to the uber-short chainstays. As you can see from the photo, there’s significant chainring/tire overlap, which just wouldn’t have been possible with a standard chainstay: In order to shorten the chainstay as much as possibly they created an elevated chainstay on the drive side in order to route above the crankset, around the wheels, and over the derailleur. Perhaps one of the most interesting things about the frame design is how exactly Trek got that chainstay length so short.
#TREK STACHE 7 REVIW PRO#
The Stache 9 is in the trail hardtail category of bikes, with a 67.5-degree headtube angle, the super-short chainstays mentioned above, and 110mm of fork travel.Īs for component spec, the Stache comes with SRAM’s X1 drivetrain, the new Manitou Magnum 29+ Pro fork, KS Dropper Post, and Bontrager’s Chupacabra tires. In fact, these are the shortest chainstays that Trek has ever engineered–405 to 420mm (presumably depending on where you have the dropouts set). This provides stiffer wheels, improved chain/tire clearance, and shorter chainstays. In order to adequately accommodate the 29+ or 27.5+ wheels the Stache features SRAM’s all-new Boost 148/110 rear/front hub spacing and related components. The aluminum-framed Trek Stache is designed to work with 27.5+, 29″ and 29+ tires, thanks to the Trek Stranglehold dropouts. The Trek Stache reviewed here is 27.5+ compatible, but the bike I tested was running 29+ wheels/tires.
#TREK STACHE 7 REVIW PLUS#
Stay tuned for a more detailed analysis of this progression in the plus size trend once the show has finished.
For those unfamiliar, this is a mid-fat wheelsize featuring approximately 3-inch tires. The big story at the 2015 Sea Otter Classic is the widespread introduction of the 27.5+ wheelsize.
