Product Details & Specs

The innovative and best-selling Mach 4 just got better for 2011. We made it a 5/8ths of a pound lighter, yet stiffer for an even more efficient riding experience. Using the cutting-edge dw-link® suspension design, the Mach 4 accelerates instantly during hard, out of the saddle efforts and gives amazing traction while climbing and accelerating out of corners. It's downright snappy! The suspension soaks up the bumps in a smooth controlled manner that lets you go faster. The 92mm BB shell, carbon reinforced double row bearing lower dw-link(R), high-modulus carbon fiber upper link and one-piece rear triangle make for a zero-flex bike. Mountain Bike Action said it best: "It gives riders all the benefits of a shorter-stroke XC racer, like sharp acceleration and a dizzying rate of climb...and it delivers the downhill handling of a longer-stroke trail bike." We couldn't have said it better ourselves.

Beyond the Boundaries
As with all of our suspension bikes, the Mach 4 is all about striking the perfect balance. In this case that perfect balance is providing the rider with World Cup winning cross country performance, without the narrow focus. It's a race bike that shatters the boundaries between the single purpose, race day-only machine and a bike that can be ridden anywhere and everywhere. The Mach 4 has been to the top of the podium in Pro and Expert class cross country races across the country. It has proven itself in the world's toughest endurance and 24 hour events including the 24 hours of Old Pueblo, the 24 hours of Moab, the TransRockies, the Leadville 100, and even South Africa's grueling Cape Epic.

The Mach 4 is also a bike we (and many happy customers) have had the pleasure of riding all across the country on every type of terrain imaginable. It's been ridden hard on our own National Trail, traversed the technical rock- and root-strewn trails of western Pennsylvania, powered through the forests of Northern Wisconsin and Minnesota, and has tackled Fruita, Colorado as well as just about everything Moab has to offer...including Porcupine Rim-right alongside riders with 6" travel bikes.

For those not buying into the notion that more travel is always better, the Mach 4 could be considered your ultimate trail bike as well as being one of the fastest, most efficient race bikes on the planet.

Low Down on the High Tech
So what is it that gives the Mach 4 this amazing combination of pure race performance while also being a fantastic all around bike?

There are more than a few things that go into the Pivot Mach 4 that set it apart, making it truly unique in the 4" travel class. First and foremost, we designed a bike that is firm and responsive under pedaling, in or out of the saddle. The dw-link(R) suspension design, custom shock tuning, and pivot suspension rates all combine to make a bike that is a rocket in or out of the saddle, and when climbing or sprinting.

One of the primary benefits of the dw-link(R) suspension design is position-sensitive anti-squat. Put simply, the dw-link(R) is the first and only suspension design that takes into account the rider's weight and position on the bike (i.e. the rider's center of mass). When you stand up to sprint or shift your weight back to climb, your weight is the dominant force on the suspension. This bob or "squat" caused by the rider's mass shift is a good part of the reason why Propedal, SPV, Brain, lockouts and a host of various other "platform damping" solutions exist: to resist suspension bob and squat. With the dw-link's anti-squat design, the dual suspension links are positioned in such a way that your weight shifts do not result in unwanted suspension movement or "squat" under power. This allows us to tune the rear shock with lighter valving, making the bike free to absorb bumps and follow the terrain better.

We combine this with a slightly rearward travel path through the beginning 1/3rd of the travel to give the Mach 4 incredible square edge bump performance and increased traction on climbs. The combination of Pivot's suspension rates and the dw-link's anti-squat properties give the Mach 4 incredible pedaling performance, zero hesitation on acceleration, and that lively snappy feel a discriminating cross country racer demands.

At the same time, there are very few if any true pro-level XC bikes that actually get 4" of travel at the rear wheel. For most XC race bikes, "4 inches" is a number at the brochure, not at the rear wheel. This is certainly not the case with the Mach 4. Real, usable, controlled travel is another reason why the Mach 4 can go fast and maintain control in technical terrain that will completely overwhelm the suspension on other cross country bikes.
