When it was first unveiled, Pivot's Mach 6 Carbon frameset inspired a lot of talk of baskets, eggs, and going all in with the Mach 6's unparalleled enduro capabilities. We're not normally suckers for industry hype, but let's just say that the Mach 6 -- easily among the most advanced carbon chassis on the market, owing to Pivot's insistence on taking its time in development -- and SRAM drivetrain included here have got our eggs by the basket. Riding on the venerable DW-Link suspension, we're confident that they'll make it to the summit and back in one piece. While the Mach 6 has myriad benefits over other manufacturers' rush-to-production 27. 5-inch all mountain bikes, we'll only take the time to focus on a few defining elements of its geometry. First, its bottom bracket height is low, settling the center of gravity within the rolling stock (like 29ers) and not on top (like 26ers and rush-job 27. 5s). Second, the top tube is around an inch longer and the chainstays are around a half-inch shorter than comparable machines, so you'll enjoy all the benefits in stability and handling of the larger frame/short stem/wide bar trend in enduro bikes without the usual penalty of a longer wheelbase. The key to this win/win/win situation is Pivot's use of a new clevis to connect the rear shock to the rear triangle. This keeps the suspension linkage compact to avoid seat tube interference, so your stays stay stubby. It also eliminates the failure-prone rear shock bushing, and you'll be happy to know that it's not proprietary, so you're free to choose whichever shock you want. Conversely, you could just stick with the included FOX Float CTD Kashima, which guarantees that the Mach 6's two carbon triangles will play nicely together while keeping unruly changes in altitude and terrain in check with its Climb Trail Descend toggling. Whatever you decide, your chosen shock will be incorporated into the Mach 6's DW-Link suspension design. Again, in the interest of time, we'll simplify...
