Introducing the new PIVOT Mach 4 SL

The all-new Mach 4 SL is designed to let World Cup level athletes capitalise 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.

The all-new Mach 4 SL is designed to let World Cup level athletes capitalise 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.

Stemming from the original Mach 429SL, the Mach 4SL has been reinvented from the dirt up. The new streamlined frame has a starting weight of 1845 grams and complete builds around the 10kg mark, making it an ultra light thoroughbred race machine. Throw in 100mm of the renowned dw-link® suspension & progressive XC geometry, and you have a bike designed for performance on the XC laps and trails. With a slacker head angle, longer reach and shorter stays, the bike instills confidence on fast, tricky descents whilst the dw-link® provides ultimate pedal efficiency.

 

The rear Boost™ spacing (12x148mm) and ability to use a 100 or 120mm fork is competitive with modern XC bike standards, but the beauty lies in the ride quality that sets it above the rest.

The World Cup calibre full carbon frame also features leading edge materials and Pivot’s proprietary Hollow Core Internal Moulding Technology to ensure durability without compromising weight and has been designed for the Fox Live integration and compatibility with dropper posts. It also boasts a full length internal cable routing via Pivot’s exclusive, easy to maintain Cable Port System.

 

 

PIVOT Mach 4 SL Key Features


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 1930 grams (including shock), 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 . Optimized tube shapes, a more compact frame design, exotic hi-mod materials, and a dual upright, reinforced swingarm push strength and stiffness while allowing weight to be shaved everywhere. More weight evaporates with an integrated headset and race-proven carbon suspension bearing pockets that leave almost no metal in the frame. 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. Plus, five different settings ranging from Pro level World Cup firm to trail riding plush are a mere push of a button away. 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 stand over 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.

 

World Cup Inspired Geometry


Technical features and dropper posts are now a common part of World Cup cross country racing, so geometry needs have evolved. The Mach 4 SL comes with a slacker head angle, longer reach and shorter stays for a whole new feel and confidence on fast, tricky descents. What was formerly sketchy, steep and nervous is now stable, planted and responsive - traits that cut precious seconds off lap times and save energy for that final sprint to the line. What’s more, the new school geometry also lets this cross-country race bike flirt with trail bike versatility outside of the course tape. If fast is fun, this might be the most exciting bike we’ve ever made.

 

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 pedalling 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.

Looks nice, I prefer this look to the bent look of the Mach429. I would have a bit more rear travel.

Top end build is $11k. Its light but I'd still buy a Momsen for marathons!

Saving up to build a top end XC / marathon bike and this is looking sweet! Head tube angle of 67.7 - 68.5 looks great, and close to what I'm used to with my Trance.

where can one get those Togs on the handlebars locally?if at all.

So they changed if from a Santa Cruz Tall Boy to a Giant Anthem.. All these have solid rear triangles resulting in a 4 bar link suspension setup Santa Cruz call it VPP, Giant call it Maestro. 

 

The Mach429SL has a horizontal shock like Santa Cruz

The new Mach 4SL has a vertical shock like the Giant Anthem.

The designs are similar indeed, but all behave quite different. 

 

VPP is two links rotating in opposing directions while Maestro and DW-Link are two links moving in the same direction.

The result is in the little details such as wheel paths and leverage ratios. 

 

Maestro suspension is in fact so similar to DW-link that the founder of DW (Dave Weagle himself) sued Giant for patent infringement and WON the case. 

Despite this the two behave quite differently on the trail. 

 

There is only so many directions you can mount a shock when designing bikes with the same/similar suspension layouts.

great looking bike right in the same park as the Intense Sniper.

Awesome looking bike! Are there demo bikes available in the Cape Town area?
