Whether slaying local singletrack or powering through to the podium, the Pivot Mach 4 SL is a popular choice with the Herd when we need a reliable, lightning-fast cross-country bike. We love the Pivot Mach 4 SL for its ultralight frame, adjustable travel, and recent frame improvements that don't lose sight of its race origins. Pushing the boundaries to make the Mach 4 SL more capable, Pivot elevated what a cross-country race bike could be and made various improvements to the bike's geometry for an enhanced ride. A slacker head tube, steeper seat tube, and longer chainstays, reach, and wheelbase all aid the Mach 4 SL in being more capable and faster in the ever-evolving world of cross-country bikes. The Mach 4 SL also features a new rocker link with a flip chip for adjustable travel. Now equipped with 106mm of premium DW-Link suspension over the previous 100mm, the Mach 4 SL is more capable than ever and also gives us the option of changing to 115MM when we flip the chip in the shock link. With a 66. 7-degree head tube angle and a longer reach and wheelbase, we are more composed and confident when descending steeper technical terrain. A steeper seat tube angle puts us in a more efficient climbing position to make short work of the technical climbs, and a lower standover height allows for longer dropper posts so riders of every size can get the perfect fit. The improved DW-Link suspension and redesigned rocker link bring us more travel, more efficient pedaling performance, and improved traction in various scenarios. Short and snappy chainstays, a lightweight frame, improved geometry, adjustable travel, and 29-inch wheels allow the Pivot Mach 4 SL to dominate the cross-country scene while still being able to compete when it's time to ride more technical trails. The Ride SLX/XT build of the Pivot Mach 4 SL is race-ready and has quality components that won't break the bank. First up, all builds of the Mach 4 SL received a revised frame that not only included multipl...
