The Gravity Defying Cross Country Rocket Ship

The all-new Mach 4 SL is designed to let World Cup level athletes capitalize on every inch of increasingly technical courses and generate speed where others hesitate. Our engineers have pushed the boundaries in every conceivable metric of cross country performance. It’s the lightest, fastest 100mm travel XC race bike we’ve ever developed. Go ahead, turn yourself inside out and leave it all out on the race course because the new Mach 4 SL leaves nothing on the table.

Watch the speedy new Mach 4 SL in action under Pivot athletes Chloe Woodruff and Taylor Lideen.


Weighty Goals

Cross country racers know that every gram counts. Pivot’s engineers didn’t set out to cut a few grams – they insisted on slashing hundreds. Starting at 1845 grams, the Mach 4 SL takes a front row seat in the ultralight full suspension category and has the best stiffness to weight ratios we’ve ever created. The new Mach 4SL is over 300 grams lighter than its feathery predecessor, the Mach 429 SL - that’s ¾ of a pound! Steep climbs and sharp accelerations never felt so good – or fast.

The Fox Live Valve Advantage

The Mach 4 SL frame features full Fox Live Valve integration for next level cross country suspension. Live Valve’s electronically activated suspension system senses impacts and knows when you’re climbing or descending. It reacts to the terrain 100 times faster than the blink of an eye, so you never feel the system actuating; the suspension is just perfect all the time. The system automatically activates tens of thousands of times during a race or ride for the ultimate in pedaling efficiency and control in rough terrain without any rider input. The efficiency benefits are undeniable, and the speed gained on every part of the course is truly mind-blowing.

Short or Tall, it Fits Them All

Proper fit is critical to maximizing our body’s output, so we made sure the Mach 4 SL fits the widest range of riders and all genders without compromise. The extra-small size fits riders down to 4”10” with a lower standover height than even our Mach 4 Carbon with 27.5” wheels, and the extra-large size fits riders up to 6’7” tall. A shorter stack, longer reach, and steeper seat angle put you in a powerful position to churn out the watts mile after mile. Size-specific carbon layups and shock tunes make sure all riders experience the same cutting edge performance and ride across the size range.

Powered by dw-link®

The shock layout may be different, but the 100mm travel dw-link® suspension keeps its legendary and familiar ride qualities: ultimate pedaling efficiency, reactive to impacts under power, and fully active while braking – its everything you want in an XC race suspension system. New metric shock with size specific tunes provide more support, control, and speed than ever before.


The new Mach 4 SL will be available in three color options—Team Blue, Cherry, and Stealth. It is available as a frame, frame kit, and a complete bike in multiple configurations, ranging from $5,299 to $17,999 AUD. The Mach 4 SL is available now in Australia exclusively distributed through JetBlack Products
