Lightweight Full Suspension Bike for Trail and Enduro Riding

Pivot Mach 4 SL Ride SLX/XT – Ice Blue

The Pivot Mach 4 SL Ride SLX/XT – Ice Blue is a lightweight full-suspension cross-country mountain bike designed for riders who want efficient climbing, sharp handling, and dependable performance on technical XC trails.

Built around Pivot's Hollow Core carbon frame and DW-Link suspension platform, the Mach 4 SL combines a 120 mm FOX front fork with approximately 95 mm of rear travel in this Ride SLX/XT configuration. Its 29-inch wheels, Shimano XT/SLX 12-speed drivetrain, and lightweight XC components make it equally suited to fast singletrack, long-distance riding, training, and competitive cross-country use.

Finished in Ice Blue, this build combines an understated appearance with a performance-focused component package.

Hollow Core Carbon Frame

The Mach 4 SL uses Pivot's Hollow Core carbon construction, engineered to deliver a strong stiffness-to-weight ratio without adding unnecessary mass.

The frame is designed with size-specific ride characteristics so that handling and frame response remain consistent across different frame sizes. Pivot also incorporates internal cable routing and frame protection around areas exposed to trail debris and contact.

Large bottle clearance makes the frame practical for both racing and longer XC rides. Medium through XL frames can accommodate additional bottle storage, while all sizes provide room for a large bottle inside the front triangle.

DW-Link Suspension

The Mach 4 SL's DW-Link suspension is tuned around efficient power transfer and reliable rear-wheel traction.

The Ride SLX/XT configuration uses approximately 95 mm of rear travel with the appropriate shock setup, while the frame platform can support alternate travel configurations. Pivot's technical information lists the Mach 4 SL platform across a range of rear and front travel settings, allowing the same basic frame design to be adapted for different XC riding requirements.

The suspension is designed to stay efficient under pedaling forces while remaining active over roots, rocks, and uneven surfaces.

FOX Performance Step-Cast 34 Fork

At the front, the bike uses a FOX Performance Step-Cast 34 29-inch fork.

Fork Specifications

• 120 mm travel

• 44 mm offset

• GRIP damper

• Air spring

• 34 mm chassis

The Step-Cast design reduces unnecessary material around the lower legs, helping keep the fork light enough for an XC-focused build. At the same time, the 34 mm chassis and 120 mm travel provide additional control when trails become steep or technical.

FOX Performance Float Rear Shock

The rear suspension is controlled by a FOX Performance Float air shock.

The shock is matched to the Mach 4 SL's DW-Link suspension system and provides approximately 95 mm of rear travel in the documented Ride SLX/XT configuration.

Its air-sprung design keeps the suspension system lightweight while allowing the rider to tune spring pressure and damping for rider weight and terrain.

Shimano XT/SLX 12-Speed Drivetrain

The Ride SLX/XT build combines Shimano XT and SLX components to deliver a broad-range 12-speed drivetrain.

The Shimano XT M8100 SGS rear derailleur provides the rear shifting, while the SLX M7100 I-SPEC EV shifter controls gear changes from the handlebar. A 10–51T Shimano SLX cassette gives the bike a low climbing gear without sacrificing useful higher ratios for fast XC sections.

Drivetrain Specifications

• Shimano XT M8100 SGS rear derailleur

• Shimano SLX M7100 I-SPEC EV shifter

• Shimano SLX M7100 10–51T cassette

• Shimano CN-M7100 12-speed chain

• Race Face Ride crankset

• 32T chainring

The combination of the 32T chainring and 51T largest cassette sprocket provides a practical climbing range for steep XC terrain.

Shimano SLX Hydraulic Brakes

The Mach 4 SL Ride SLX/XT uses Shimano SLX M7100 two-piston hydraulic disc brakes.

The documented configuration uses 160 mm Shimano SLX six-bolt rotors front and rear. This braking setup is appropriately matched to the bike's XC focus, keeping weight down while delivering predictable stopping power and modulation.

29-Inch Wheelset

The 29-inch wheel platform gives the Mach 4 SL efficient rollover and helps maintain momentum over roots, rocks, and other trail obstacles.

Earlier Ride SLX/XT builds use DT Swiss X1900 wheels with DT Swiss 370 hubs and 25 mm rims, while later documented builds use Newmen Performance 30 mm wheels. The actual wheelset should therefore be matched to the model year of the bike being sold.

Wheel Specifications — Earlier Ride Build

• 29-inch wheels

• DT Swiss X1900 rims

• DT Swiss 370 hubs

• 25 mm rim width

• 15 x 110 mm front spacing

• 12 x 148 mm rear spacing

Maxxis Ardent Race Tires

The documented Ride SLX/XT configuration uses Maxxis Ardent Race 29 x 2.2-inch tires.

The tires feature TR tubeless-ready construction, EXO casing, and 120 TPI. Their tread pattern balances rolling speed with sufficient cornering and braking traction for XC and technical trail riding.

The 2.2-inch width also helps preserve the bike's fast, lightweight character.

Dropper Seatpost

A dropper seatpost is included with the Ride SLX/XT build, allowing the saddle to be lowered from the handlebar when descending.

Documented configurations vary by model year. Earlier builds list a FOX Transfer Performance Elite, while later specifications identify an SDG Tellis for Medium through XL sizes and a FOX Transfer Performance Elite for XS–Small.

Typical documented travel ranges include:

• XS–SM: approximately 105–125 mm

• MD–LG: approximately 130–150 mm

• XL: approximately 150–175 mm, depending on model year

A dropper adds useful control on technical descents without compromising the bike's XC-oriented design.

XC-Focused Cockpit

The Ride SLX/XT uses Pivot's Phoenix cockpit components:

• Phoenix Race Low Rise Aluminum handlebar

• 780 mm width

• Phoenix Team XC/Trail stem

• 60 mm stem

• Phoenix Factory Lock-On grips

The 60 mm stem and 780 mm handlebar provide a balanced combination of steering leverage and XC-oriented positioning.

Frame Practicality

Although the Mach 4 SL is designed around racing efficiency, the frame includes features intended for everyday trail use:

• Internal cable routing

• Pivot Cable Port System

• Large bottle clearance

• Molded frame protection

• Tool and accessory mounting provisions

• UDH-compatible rear derailleur hanger

• Size-specific carbon construction

• Travel-adjustable suspension configuration

The frame also has clearance for tires up to approximately 2.4 inches, giving riders some flexibility beyond the stock 2.2-inch XC tires.

Technical Specifications

*Later Ride SLX/XT builds are documented with Newmen Performance 30 mm wheels, so the wheel specification should be verified against the exact model year and inventory configuration.

Available Sizes

The Mach 4 SL platform is offered in:

• XS

Pivot uses size-specific frame tuning to maintain consistent handling characteristics across the size range.

Why Choose the Mach 4 SL Ride SLX/XT?

The Pivot Mach 4 SL Ride SLX/XT – Ice Blue strikes a strong balance between XC race efficiency and real-world trail capability.

Its lightweight carbon frame keeps the bike responsive, while the DW-Link suspension provides traction without making the bike feel sluggish under power. The 120 mm FOX Step-Cast fork adds confidence on technical descents, and the Shimano XT/SLX drivetrain offers a wide 10–51T range for steep climbs.

The 29-inch wheels help the Mach 4 SL carry speed and roll efficiently over obstacles, while the dropper post adds another level of control when the trail points downward.

For riders seeking a fast, lightweight, efficient, and technically capable XC bike, the Mach 4 SL Ride SLX/XT provides a well-rounded package without sacrificing the lively handling expected from a dedicated cross-country platform. Pivot describes the Mach 4 SL as an XC bike focused on efficiency, precision, and control, with DW-Link suspension designed to maintain traction and acceleration.
