High Performance Full Suspension Bike with Carbon Wheels for Trail

Pivot Mach 4 SL Pro XT/XTR Factory Float (Carbon Wheels) – Ice Blue

The Pivot Mach 4 SL Pro XT/XTR Factory Float (Carbon Wheels) – Ice Blue is a high-performance full-suspension cross-country mountain bike designed for riders who want race-ready efficiency combined with modern trail capability.

Its lightweight carbon frame works with Pivot's DW-Link suspension platform to deliver efficient power transfer, dependable rear-wheel traction, and controlled handling over technical terrain. The premium build pairs a FOX Factory Step-Cast 34 fork and FOX Factory Float rear shock with a Shimano XTR/XT 12-speed drivetrain and a lightweight Reynolds Blacklabel carbon wheelset.

Finished in Ice Blue, this configuration is aimed at riders who value quick acceleration, low rotating weight, precise handling, and premium components without moving away from the Mach 4 SL's XC-focused character.

Lightweight Mach 4 SL Carbon Frame

The Mach 4 SL is built around Pivot's Hollow Core carbon construction, giving the frame a high stiffness-to-weight ratio suitable for fast cross-country riding.

The Gen 3 Mach 4 SL was redesigned to reduce frame weight while increasing capability. Pivot's size-specific carbon tuning is intended to provide consistent handling characteristics across the available frame sizes rather than simply scaling the same layup from one size to another.

The frame also incorporates internal cable routing, protection in high-wear areas, modern Boost axle spacing, and generous water-bottle clearance. Pivot's Gen 3 platform uses a flip-chip system that allows the suspension configuration to be adjusted for different travel and geometry settings.

DW-Link Suspension

Pivot's DW-Link suspension system is designed to balance pedaling efficiency with active suspension performance.

For this specific Pro XT/XTR carbon-wheel configuration, the FOX Factory Float rear shock provides 95 mm of rear travel, while the front suspension provides 120 mm. The setup is intended to keep the bike efficient on climbs while maintaining traction over roots, rocks, and other trail irregularities.

The Mach 4 SL platform is particularly well suited to riders who want the acceleration and efficiency of an XC bike without giving up useful suspension performance on technical descents.

FOX Factory Step-Cast 34 Fork

The front end uses a FOX Factory Step-Cast 34 29-inch fork.

The documented 2024 carbon-wheel build features:

• 120 mm travel

• 44 mm offset

• GRIP SL damper

• Air spring

• 29-inch wheel compatibility

The Step-Cast chassis is designed to reduce unnecessary weight while maintaining the stiffness required for accurate steering. Its 120 mm travel gives the Mach 4 SL additional control when trails become rough or steep.

FOX Factory Float Rear Shock

A FOX Factory Float controls the Mach 4 SL's rear suspension.

The shock works with the DW-Link platform to provide controlled suspension movement while preserving efficient pedaling characteristics. The documented configuration provides 95 mm of rear travel.

The air-sprung design also allows the suspension to be adjusted to suit rider weight, riding style, and trail conditions.

Shimano XTR/XT 12-Speed Drivetrain

The drivetrain combines Shimano's high-end XTR rear derailleur with XT shifting and cassette components.

Drivetrain Components

• Shimano XTR M9100 SGS 12-speed rear derailleur

• Shimano XT M8100 I-SPEC EV 12-speed shifter

• Race Face Æffect R 34T crankset

• Shimano XT M8100 10–51T cassette

• Shimano CN-M8100 12-speed chain

• 1×12 drivetrain

The 10–51T cassette offers a broad range of gearing for steep climbs while maintaining higher gears for fast sections of singletrack. The XTR rear derailleur provides precise shifting with a premium, race-oriented component design.

SRAM Level Silver Hydraulic Brakes

The documented 2024 carbon-wheel build uses SRAM Level Silver two-piston hydraulic disc brakes.

The two-piston configuration is appropriate for the bike's XC-focused design, providing controlled braking without adding the weight associated with larger trail or enduro brake systems.

Because earlier versions of the Mach 4 SL Pro XT/XTR were sold with Shimano XT brakes, the exact brake specification should always be matched to the model-year build when listing a specific inventory unit.

Reynolds Blacklabel Carbon Wheels

One of the biggest upgrades in this configuration is the Reynolds Blacklabel carbon wheelset.

The documented wheel specification is:

• Reynolds Blacklabel 309 XC front rim

• Reynolds Blacklabel 289 XC rear rim

• Industry Nine Hydra hubs

• 29-inch wheel size

• 30 mm front rim width

• 28 mm rear rim width

• 15 × 110 mm front axle

• 12 × 148 mm rear axle

The carbon rims help reduce rotating weight and provide a responsive feel when accelerating. Industry Nine Hydra hubs are known for their quick engagement, which can be useful when navigating technical climbs, tight corners, and repeated pedal inputs.

Maxxis 29 × 2.4-Inch Tires

The documented 2024 carbon-wheel configuration uses Maxxis 29 × 2.4-inch tires, with the listing identifying the front/rear specification as Rekon and Rekon Race variants.

The tires use:

• 29-inch diameter

• 2.4-inch width

• Tubeless-ready construction

• EXO casing

• 120 TPI casing

• 3C compound on the listed Rekon specification

The 2.4-inch format gives the Mach 4 SL additional traction and volume compared with earlier 2.2-inch configurations while remaining within the frame's approximately 2.4-inch tire-clearance limit.

FOX Transfer Factory Dropper

The FOX Transfer Factory Series dropper seatpost allows the saddle height to be adjusted quickly from the riding position.

Typical travel varies by frame size, with the documented configuration using approximately:

• XS–SM: 125 mm

• MD–LG: 150 mm

• XL: up to 210 mm depending on configuration

A dropper is especially useful on technical descents because lowering the saddle gives the rider greater freedom to shift body position and maintain control.

Phoenix Carbon Cockpit

The cockpit uses lightweight Phoenix components selected for XC performance.

Cockpit Components

• Phoenix Team Flat Carbon handlebar

• 760 mm width

• Phoenix Team XC/Trail stem

• 60 mm stem

• Phoenix Factory Lock-On grips

• Phoenix WTB Pro Volt narrow saddle

The carbon handlebar keeps the cockpit weight low while providing a stable platform for fast steering and technical trail riding.

Practical Frame Features

The Mach 4 SL is designed around both racing efficiency and everyday trail usability.

Frame Highlights

• Hollow Core carbon construction

• DW-Link suspension

• Flip-chip suspension adjustment

• Internal cable routing

• Pivot Precision Sealed Integrated Cartridge headset

• Two water-bottle mounts on suitable frame sizes

• Large bottle clearance

• Molded downtube and chainstay protection

• 29-inch wheel platform

• Up to approximately 2.4-inch tire clearance

• Boost 15 × 110 mm front and 12 × 148 mm rear spacing

The frame's carbon construction is particularly light; published specifications put the small frame at approximately 1,660 g without the rear shock.

Model-Year Specification Note

The name Mach 4 SL Pro XT/XTR Factory Float (Carbon Wheels) covers more than one model-year specification. The 2024 build documented for this exact carbon-wheel configuration uses GRIP SL fork damping, SRAM Level Silver brakes, Reynolds Blacklabel 309/289 XC wheels, and 29 × 2.4-inch Maxxis tires. Earlier versions can differ—for example, some listings show FIT4 fork damping, Shimano XT brakes, and narrower 2.2-inch tires.

For an individual inventory unit, the manufacturer's build sheet or the physical bike's component specification should take precedence over generic model-year information.
