Winner of trail bike and XC bike awards, as well as professional races around the world, the Mach 4 Carbon perfectly embodies our philosophy of designing every Pivot to perform at the pinnacle of its category. For riders seeking the ultimate in lightweight trail bikes, the flickable, confidence inspiring Mach 4 Carbon shines in technical terrain, and anywhere the singletrack gets rough. For racers, the ability to unleash on descents is matched only by the Mach 4 Carbon’s World Cup pedaling efficiency and power transfer. Whether it is time to cut loose on your favorite trail or crush the competition at your next race, the Mach 4 Carbon is one bike that does it all.


From the Epic race series, to the Sea Otter Classic, to the Pan Am Games – the Mach 4 Carbon has put athletes on podiums around the world. As race courses evolve to be as technically challenging as some backcountry epics, Pivot’s next generation race/trail geometry is the answer to hitting everything just a little bit faster on every lap.

The Mach 4 Carbon frame is produced using our proprietary hollow core internal molding process, combined with highly optimized layup structures, tube sections, and material choices, tuned for the optimum ride-feel in every size. Frames weigh as little as 5.1lbs (2.3kg) and complete bikes are available under 22 (10kg) lbs.

The new Mach 4 Carbon features a fully redesigned rear triangle with increased stiffness and more tire clearance. The confident handling of the Mach 4 Carbon is complemented by the mid-sized 27.5- wheels with new 148mm BOOST rear hub spacing – all together, providing instant response while maintaining rolling speed through even the roughest sections of a racecourse.


“The Mach 4 Carbon is, hands-down, the best pedaling full-suspension bike out there. It’s become my go-to World Cup race bike. The DW-link suspension not only allows me to attack the technical descents but allows me to climb more efficiently through increased seated and standing traction.-
– Chloe Woodruff, Stan’s NoTubes / Pivot

dw-linkåÈ suspension offers every advantage to the Mach 4 Carbon rider. Tuned to provide instant acceleration with no loss of power, the Mach 4 Carbon delivers incredible climbing traction on even the loosest tracks, while the short chainstays, spacious cockpit, and the incredibly stiff carbon chassis enable you to tackle uphill technical challenges you’ve never dreamed of cleaning. When descending, the Mach 4 Carbon reveals its trail-bike chops. With ultra-stable geometry, a low BB height, and 115mm* of dw-linkåÈ suspension, you can unleash on technical features and square edge hits with confidence and speed.


Mach 4 Carbon is spec’d with the Fox Float DPS (Dual Piston System), tuned to provide pro-level, World Cup quality, pedaling performance and the bottomless feel of a longer travel bike without sacrificing efficiency. The Float DPS shock features settings and a design that allows for an incredibly plush feel with a wide range of damping control while also offering an extremely positive “firm- position for fast climbs. These features are direct complements to Pivot’s suspension tuning and when combined with the dw-link’såÈ patented position-sensitive anti-squat, gives riders even better traction on steep ups and over rough trail.


“Not just marketing hype, Pivot’s revamped Mach 4 Carbon does have the skills to redefine XC performance. An efficient climber, it left the field for dead on the descents and dominated the test. A well-deserved winner!-
– Enduro Magazine, Mach 4 Carbon wins Best in Test

The Mach 4 Carbon complete bikes are built with an ideal combination of components for riders seeking a fast, capable trail-ready bike. For riders seeking high performance, trail bike capability on technical terrain and high-speed descents, the sub-4 lb., 130mm travel Fox 34 embodies confidence and control. Additional complete bike highlights include Maxxis Ardent 2.35 tires and 740mm wide riser bars with shorter stems per size catering to a more trail oriented riding style.


The Mach 4 Carbon is a race-tested and proven choice. For competitive athletes, we offer the Mach 4 Carbon complete bikes with an optional XC Race package. This podium-ready build includes the very light 100mm Fox 32 Step Cast fork **, fast rolling Maxxis IKON 2.2- tires and a Phoenix Team Flat Carbon handlebar. For riders who seek to save every second, and whose primary purpose is cross-country racing, the XC Race package turns the Mach 4 Carbon into the fastest ride to the finish line.


The Mach 4 Carbon is available in five sizes to fit riders from 4’10- to 6’3-+ from Extra Small (XS) to Large (L) and Large (Long) options. Smaller stature riders will be happy to know that the XS frame fits a large waterbottle in the front triangle, sizes S-L all fit 2 large bottles in the front triangle. With the Mach 4 Carbon’s very low stand over height, riders seeking the a more trail bike oriented fit are able to go up a size and run a shorter stem – the resulting longer front-center is ideal in more technical terrain. The addition of the Large (Long) to the Mach 4 Carbon line-up enables a wider size range of riders to take advantage of this fit strategy.

Getting the gearing setup that works best for you is easy with the Mach 4 Carbon. It is both 1x and 2x compatible, and offers full Di2 electronic integration and easy, clean internal routing of shifters, brakes and droppers via the Pivot Cable Port system.

Other essential details include rubberized leather downtube and swingarm frame protection, 160mm rear post mount disc brake, and Enduro Max cartridge bearings throughout.


The Mach 4 Carbon is offered in 5 sizes to fit a wide range of rider sizes and riding styles. At Pivot, we believe the bike should fit the rider, not the other way around. Our approach to rider-size-specific geometry relies on a balanced fit and adjusted geometry to maintain correct wheelbase length and handling to properly accommodate the proportions of a smaller rider. Our smaller sizes are built with shorter head tubes to create more stand-over height. This enables you to ride in a centered, athletic position with tons of clearance over the top tube – essential to descending and cornering with confidence and speed.

Size-specific carbon molds enable us to use smaller diameters and unique carbon layups for lighter frames while maintaining the same high strength in a more compact frame design. We can give you the same pedaling efficiency and stiffness experience as a rider of any size by engineering specifically for small and extra small frames. Additionally, for riders on our extra small bikes, lighter shock tuning and leverage rates enable us to set up the Mach 4 Carbon for a diverse range of rider weights and abilities.

Pivot complete bikes are also designed to intelligently address real-world rider differences, with the option to choose women’s specific saddle on any size as well as shorter crank lengths our XS sizes.


Pivot complete bikes are more than the sum of their parts – every single component is selected to give you the best experience on the trail:

Tires: For each of our bikes, we include the best version of every Maxxis tire model for each application – choosing rubber compounds, tubeless and sidewall technologies that are perfect for your specific Pivot.

Cockpit: Custom designed Phoenix Components work as a system to enhance cockpit comfort and control on every Pivot bike. To learn more about how these components enhance the quality of your ride, see here.

Wheels: Wheels: All Pivot bikes include the best wheel technologies available from our partners. The Mach 4 Carbon complete bikes include choices from both DT Swiss and Stan’s, in high performance carbon and alloy rim options, wide internal rim widths, easy to set up and reliable tubeless systems, and quick engagement hubs for immediate engagement off the line.

Saddle: Pivot bikes feature WTB saddles that are specially made with the best, most durable, memory foam and feature a special hidden cutout for long ride comfort. The LES 2.75 complete bikes include rider’s choice of either the high performance Volt saddle or the Deva women’s saddle.

We take quality and workmanship seriously at Pivot, and know that the details are what make a great rider experience. Every Pivot Cycles frame undergoes a 28-step assembly and quality control check to ensure that every ride on the Mach 4 Carbon exceeds your expectations.

*X-Small size features 100mm travel. See FAQ tab for more information.
** The Mach 4 Carbon frame is designed for 27.5- wheels with tires up to 2.6- wide, and the Fox 34 also fits tires up to 2.6- wide*. However, the FOX 32mm Step-Cast Fork is only designed to accept up to 2.3- tires. If you wish to run 2.6- tires on your LES 27.5, we recommend ordering your bike with our FOX 34mm fork option.
