Chris claims this setting “yields a very playful ride, which finds the rider lofting over obstacles and popping off jumps”. These allow you to run the Stache with a slammed 405mm chainstay length, but only if you’re running a 27.5x3in or 29x2.35in rear tyre (this does mean you’ll need to use a longer travel fork up front to maintain similar geometry though). Then there are the ‘Stranglehold’ sliding dropouts at the rear. Look even closer at the underside of the bottom bracket and you’ll see a carved-out notch to optimise clearance for mud and tyre.” This allows us to maintain stiffness and proper clearances. Drewes says: “Look at the non-driveside chainstay and you’ll see that we have a one-piece forging of the bottom bracket and part of the chainstay. We all know that trails rarely stay bone dry, especially here in the UK, so decent mud clearance was essential too. It took Trek numerous attempts to create an elevated stay that offered the right combination of stiffness and clearance. Though this means saying adios to the front mech, this design – combined with the new SRAM-backed Boost hub standard (15x110mm front, 12x148mm) – has enabled Trek to keep the back end of the bike short even with a 3in tyre in place and maintain a lively feeling on the trail. Packaging big wheels in a frame that maintains the lively feel everyone yearns for isn’t easy, so how do you fit even bigger wheels in place without waving bye-bye to decent handling? As you can see, the Stache sports an elevated driveside chainstay. The same gains going from 26in to 29in wheels are realised in going from 650+ to 29+.”

“Twenty-nine plus delivers a more pronounced benefit, especially for hardtails. Why opt for the bigger of the two ‘plus’ sizes? “More rollover, momentum and traction, equalling a confidence inspiring, super-capable ride,” says Chris Drewes, Trek’s MTB Hardtail Product Manager. Trek are one such company, and they’ve thrown their considerable weight behind the larger 29+ format (3in tyres on wide 29in rims) with the new Stache hardtail. While we’re seeing most manufacturers settle on the more conservative 650b+ standard (2.8-3in tyres on wide 650b rims), some like to push things that little bit further. Just when we thought we were getting on top of all the wheel sizes the industry has thrown at us, along come ‘plus-size’ bikes andmyriad new dimensions to get our heads around.
Wide rims, wide tyres and big 29in hoops mean the Stache can tackle just about anything in its path Boost technology helps to create stiffer wheels and allows more clearance for wider tyres
Trek’s sliding Stranglehold dropouts offer 15mm of chainstay length adjustment (405-420mm) and can accommodate 650b+, 29in and 29+ wheels Could Trek’s Stache be the plus-size playbike we’ve been waiting for?
