Pivot Mach 4 SL Top Tier Build

Pivot allows riders to select the highest-end components, beginning with the Build. ‘XC’ Builds feature a 120mm fork, while World Cup Builds feature a 100mm fork. A ‘Team’ build level will line you up for Shimano or SRAM drivetrain options (XTR or XX1 AXS). Next, choose your fork––FOX Factory Forks come on all Pro or Team Builds (DPS or LIVE). Reynolds Blacklabel Carbon Wheels are an option for the Pro or Team Builds and are complemented by i9 Hydra Hubs.

Pro and Team build kits offer the electrifying upgrade option to FOX Factory Live suspension––battery-powered sensors optimize your fork and shock settings according to how and what you’re riding, while you're riding. And an app makes it easy to manually adjust settings as you need.

The Best Pivot Mach 4 SL Value Builds

For the budget-conscious rider, the ‘XC-Ride’ build, with either Sram GX Eagle or Shimano XT components and a FOX Performance DPS fork, offers reliability, durability, and the same Hollowcore® frame technology. The ‘Ride’ build will come with high-performance alloy DT Swiss wheels and hubs. Whether this bike is challenged on training efforts or lining up for an event, this build option is tenacious!

The Pivot Mach 4 SL is front and center in the ultralight Cross Country category, making this an easy choice if you’re looking for the lightest race bike. The Mach 4 SL has it all. There’s no debate between prioritizing weight versus rigidity or full suspension. The frame weight starts at a mere 4 lbs!

Pivot engineers utilize their Hollowcore® frame technology to cut weight without compromising strength and durability. Choose between a FOX 100mm fork for a fast race-focused suspension or a 120mm fork for a more downcountry feel suitable for long endurance rides with wide ranging terrain. All builds feature 100mm of Pivot's renowned dw-link® suspension, easy-to-find UDH derailleur hangers, optional Fox Live Suspension, and size specific geometry and tuning to fit riders 4'8"–6'7".
