5/21/2023 0 Comments 2017 trek stache 7Both aluminum and carbon bikes now offer 120mm front travel with the top end Stache 9.8 (top) receiving the new RockShox Pike 29+ fork. The carbon frames also grow at the top tube with a 15mm longer reach. The only difference between the carbon and aluminum bikes out back is a 5mm lower BB on the new carbon frame for more aggressive handling. Part of the tire clearance equation is Boost 148 dropouts matched with the PF92 bottom bracket. Both bikes feature the Stranglehold adjustable dropouts which allow for multiple tire sizes or for the use of single speed drivetrains (even belt drive thanks to the elevated stay). The elevated chain stay allows for a 405-420mm chain stay length while maintaining proper clearance for the chainrings and wide 29 x 3.0″ tires. In terms of the frame details, the Stache 9.6 and 9.8 carbon frames are very similar to their aluminum counterparts. Built with the same features, the carbon bikes do offer improved geometry which will make them even more capable as all around rippers… Now, Trek is expanding on that initial Stache with the addition of two carbon frames. In the mind of Trek’s designers and engineers, that was the key to making the bigger tires work in a trail capable hardtail. Built with a elevated chain stay and a PF92 bottom bracket, the design allowed for ridiculously short chain stays that would still swallow a 29+ tire. Even though Salsa beat Trek to the punch by showing us the carbon 29+ Woodsmoke at Saddle Drive, Trek has been catering to the 29+ crowd for some time with their aluminum Stache. I suppose an ankle pad would be an option for a long-term fix.Showing their commitment to huge tires and elevated chain stays, the Trek Stache is getting an upgrade. I spaced out the bottom bracket and pedal a bit, which helped, but it didn’t fully solve the problem. This is because it’s right at the level of my back foot in descending position. The only challenge for me, personally, is that I tended to ding my right ankle on the raised chainstay when giving it too much English or getting bounced around on rocky sections. Plus, it doesn’t fit into any of today’s bike category boxes it’s a one-of-a-kind design and riding experience. It’s reminiscent of those early ‘90s front-suspension hardtails - like my trusty Yeti ARC with a RockShox Mag 21 - but the exaggerated tires and modern technology make it feel right at home on today’s black-diamond flow trails. It’s fun because it harks back to why we started riding in the first place.namely, for fun. There’s no question: the Trek Stache is a blast to ride. When all was assembled, it tipped the scale at 26.5 pounds, which is right in line with a high-end trail bike. Other component choices include the Selle SMP 209 saddle and Chris King NoThreadset headset. Many ways to dial and adjust these brakes on the fly Reed Apparently, this is something you have to get used to with a plus bike in order to get the most out of it. It should be noted that I bottommed the rear tire on the rim on pretty much every ride - often making a loud ping! noise - but never flatted or compromised the rim in any way. Altogether, the set weighs about 1,700 grams, and each tire weighs about 900 grams. The M6 series is designed for trail use, and with an internal width of 40mm, the 640s support tires ranging from 2.8 to 3.2 inches. I sent the XTR hubs to ENVE to be built with its M640 hoops. The wheel choice, then, was pretty clear. It’s a hardtail that you punish like a full-suspension bike for the pure fun of it (with the added benefit of efficient climbing out of the saddle). This isn’t an XC hardtail, nor is it a bike for Strava PRs. One of the themes of this Stache build is that everything needs to be burly.
