Pivot Mach 4 SL Team XX SL Eagle Transmission

The Pivot Mach 4 SL Team XX SL Eagle Transmission is the lightest and highest-performing full-suspension carbon XC bike in the lineup, designed for maximum race speed, efficient climbing, and extremely precise handling on modern XC courses. The new Mach 4 SL platform combines Pivot’s highest modulus carbon fiber, dw-link suspension, and top-tier components into a package that translates every pedal stroke directly into forward motion. The Team version is built for the rider who wants the absolute fastest and lightest Pivot XC bike for racing and top-level performance.

Pivot Mach 4 SL Team – the lightest and fastest full-suspension XC bike from Pivot

The Mach 4 SL Team is built around Pivot’s highest modulus carbon fiber frame, featuring an optimized stiffness-to-weight ratio. The frame construction and geometry are designed to provide instant acceleration, efficient power transfer, and calm control as speeds increase. The updated dw-link kinematics maintain constant traction on uneven terrain while keeping pedaling efficiency at an extremely high level. This makes the bike exceptionally fast on both steep XC climbs and technical tracks where maintaining momentum is crucial.

On the Mach 4 SL, rear travel is adjustable to 110 or 120 millimeters via a flip-chip solution. The 110 mm setting emphasizes maximum race efficiency and acceleration, while the 120 mm setting increases stability and control on technical XC courses and high-speed trail riding. Up front, the Fox Factory 34SL 120 mm fork offers an extremely light yet stiff structure, precise steering, and a sensitive platform that maintains front-end control at high speeds and over rough terrain. In the rear, the Fox Factory Float shock completes the competition-level suspension performance.

The drivetrain is handled by the SRAM XX SL Eagle Transmission, which is SRAM’s lightest and most precise XC drivetrain. Featuring a direct frame mount, an ultra-light design, and high load capacity, it provides instant and accurate shifting even under heavy pedaling. The 12-speed 10–52t gear range offers an optimal combination for steep climbs and high top speeds. At the XX SL level, drivetrain mass is minimized without compromising durability, which supports the bike’s top-tier acceleration and overall lightweight profile.

For braking, the Mach 4 SL Team uses SRAM Level Ultimate 4-piston brakes, which combine an ultra-light structure with powerful modulation for XC use. The 180 mm front rotor and 160 mm rear rotor provide sufficient stopping power on technical descents while maintaining competition-level weight. This brake package supports the bike’s fast and precise nature, where control is maintained even as speed increases.

The cockpit features an all-carbon Phoenix Team Flat Carbon bar at 760 mm width and a Phoenix Team XC/Trail stem at 60 mm. The carbon handlebar provides maximum stiffness and an extremely precise steering feel, while the width offers a balance between XC efficiency and technical control. Phoenix Factory Lock-On grips complete the secure hold. The RockShox Reverb AXS dropper post increases control on descents and technical sections, and the Phoenix WTB World Cup Volt Carbon saddle offers an ultra-light, competition-level seating solution.

For wheels, the Mach 4 SL Team utilizes Reynolds Blacklabel 309/289 XC carbon wheels, which combine very low mass, high stiffness, and instant power transfer. Carbon wheels improve acceleration, precise handling, and energy efficiency in racing. The tire setup with a 2.4” Maxxis Rekon up front and Rekon Race in the rear provides an optimal combination of rolling speed, grip, and lightness for modern XC terrain. This package makes the bike an exceptionally fast yet technically capable XC race machine.

The Mach 4 SL Team XX SL Eagle Transmission represents the pinnacle of Pivot’s XC lineup. It combines the lightest frame, the lightest drivetrain, and top-tier suspension into a package designed to win races. The bike is intended for the rider who wants maximum performance, extreme lightness, and competition-level handling without compromise.

GEOMETRY

Faster where it matters

The Mach 4 SL is an XC bike in its purest form – designed for maximum efficiency, honed for precision, and built to dominate the modern race circuit. It was born from the demands of World Cup XC and long-distance endurance races, combining an ultra-light structure with uncompromising stiffness, control, and efficiency.

This is Pivot’s sharpest tool for riders who live on the edge – designed to crush climbs and respond to the demands of those real-world trails where races are truly won.

Mach 4 SL legacy

The Mach 4 SL continues the legacy of Pivot’s first bike, the Mach 4 Alloy, introduced in 2007.

The original model laid the foundation for Pivot’s focus on efficiency, suspension performance, and race-oriented handling. Since its 2019 debut, the Mach 4 SL has defined the concept of the modern XC bike: light, high-performing, and uncompromisingly fast. Each generation has refined this vision to meet the demands of today’s courses, while remaining true to the speed and precision where it all began.

Pivot’s proprietary Ride Tuning design philosophy

At Pivot, every frame size is engineered individually with precise strength-to-weight analysis and tailored carbon fiber layups.

This process ensures that a small frame size offers the same balance and performance as an XL – without compromise. By adjusting stiffness and compliance individually for every size, every rider gets the same confident handling, efficiency, and responsiveness, regardless of size. This approach is precisely what makes the Mach 4 SL feel so refined on the trail.

The Mach 4 SL also boasts the highest stiffness-to-weight ratio in the Pivot lineup, because every gram and every watt of forward power transfer are critical.

Why dw-link?

dw-link is more than a suspension solution – it is the foundation of every Pivot bike.

By combining precise anti-squat geometry with exceptional sensitivity, it delivers a ride feel that pedals efficiently while remaining stable and predictable. On the Mach 4 SL, this balance means every watt of a pedal stroke converts directly to forward motion, while traction is maintained over roots, rocks, and technical climbs. The result is efficient climbing, calm cornering, and suspension performance that supports the rider in all aspects of the trail.
