Blurring the line between lightning-fast XC rocket and nimble trail bike, the Pivot Mach 4 Carbon XT/XTR Pro DT Complete Mountain Bike is unlike anything else we've feasted our eyes on in the lightweight XC category. Tipping the scales at a svelte 5.1 pounds (size medium), the Mach 4 Carbon is the lightest full-suspension frame ever produced by Pivot. This equates to blistering acceleration the minute you step on the gas, as well as an extremely flickable feel around tight corners, which is further aided by its incredibly short 16.85-inch chainstays.
Reading about its lightweight figures, you'd be inclined to think of the Mach 4 Carbon as a purebred XC machine bred exclusively for competitive racing. And though it's sure to help you climb the rankings of your local race series, the Mach 4 Carbon is surprisingly confident and composed across technical sections of trail usually reserved for longer-travel bikes. Looking at its geometry, you'll note the 67.8-degree head tube angle (with provided 130mm fork) is a touch slacker than many XC bikes, yet decidedly steeper than its burlier trail brethren. Ultimately, this moderate geometry retains the goat-like climbing prowess you've come to love from XC bikes, but without being too steep for ripping steep descents.
Responsible for its balance between XC efficiency and trail composure, the engineers at Pivot designed the Mach 4 Carbon with 115 millimeters of DW-Link travel, which is renowned for its anti-squat characteristics while pedaling and plush, bump-absorbing feel on rock-littered descents. This particular build comes with a FOX 34 Factory fork up front that packs 130 millimeters of travel for bump-gobbling compliance across the rough stuff. On the rear, you'll find the FOX Float DPS Kashima shock comes with two sag indicators for fine-tuning its use to either XC or trail settings. This is a great feature to have if you're constantly switching between a race and trail riding set-up.
Seeing it's made to be lightweight, Pivot ditched the front derailleur on this XT/XTR 1x build, giving you an excellent 1x11 drivetrain with a wide range of usable gears. If you're coming from a 2x set-up, you'll be pleased to note its massive 46 tooth cog for spinning up the steepest climbs without fatigue. Another excellent feature, the upgraded DT Swiss XMC 1200 Wheelset drops weight with its carbon construction while increasing stiffness for precise tracking and instantaneous acceleration. These wheels are laced to DT Swiss hubs with a responsive 36-tooth star ratchet for getting up and over trail impediments with ease.
