The Pivot Mach 4 is the bike that started it all.

From the racetrack to the trail, there has never been anything that has performed like the new Mach 4 Carbon. Now in its 4th generation, the Mach 4 Carbon rolls on 27.5” wheels, features 115mm of travel*, and introduces the next generation of race/trail geometry—all paired with the lightest full-suspension frame we have ever made. Whether you are a pure XC racer looking for something nimble, with the acceleration of 26” wheels and the rolling speed of a 29er, or a trail rider that wants something fast and responsive yet stable, the Mach 4 Carbon has you covered.

The dw-link® suspension has been tuned to provide instant acceleration with hardtail efficiency, while delivering the incredible climbing traction that all our dw-link equipped bikes are famous for. The short chainstays, spacious top tubes, and the incredibly stiff carbon chassis all enable you to achieve your fastest time on the climbs. On the descents, the Mach 4 Carbon comes alive. With ultra-stable front end geometry, a low BB height, and 115mm of travel, you can tackle some of the roughest trails with ease; cornering like the bike is on rails and slicing through turns like a Ginsu knife! But we didn’t stop there.

The Mach 4 Carbon is the first Shimano Di2 compatible frame ever developed, featuring an internal battery mount in the down tube and all the required ports for clean internal routing. If you are not running Di2 and prefer a more conventional set up, the Mach 4 Carbon has the cleanest cable routing in the sport, with ports for full internal routing (including dropper post), full length housing and options for 1X, 2X and Shimano’s new M9000 Side Swing front derailleur.

*X-Small size features 100mm travel. See FAQ tab for more information.

Product Reviews

"This is the one-bike quiver. I ride my Mach 4 Carbon on the fast, flowy singletrack of Colorado and the rocky tech of Southern Utah. It performs equally well in both places. I've never had such a light bike that handled so well and climbed so fast. I'm 5'6" and ride a medium."

- Carla Hukee, Pivot Employee

"You can actually see the value here in the superb finish and zero-compromise performance. It’s lightweight yet anything but flimsy, efficient but magnificently smooth, precise without being unmanagably sharp, and it defies being pigeon holed - This bike doesn’t just continue Pivot’s legacy, it pushes the brand even further ahead of most of the pack.".

Dirt Rag – Inside Line: New Mach 4 Carbon from Pivot

06.19.2014 | Online Media

The Mach 4 has always been an important bike for Pivot Cycles. It was the brand’s first big hit, and long a mainstay of the lineup. But let’s face it, a 26-inch bike with 100mm of travel is a hard sell these days, and the new, fourth-generation Mach 4 Carbon has not only embraced all the current design trends and standards, it is creating new ones. Like all Pivot bikes, the heart of the full carbon frame...

Frequently Asked Questions

Which size bike should I purchase?

To ensure the best sizing, we recommend that you visit your local Pivot dealer to get a professional fit and refer to our geometry chart to check your measurements. However, we can provide a rough guideline:
X-Small: 4'10" – 5’5”
Small: 5'4" – 5’8”
Medium: 5'7” – 5’10"
Large: 5'10” – 6’0”
X-Large: 5'11"- 6'3"

What bottom bracket is used on the Mach 4 Carbon and which cranks are compatible?

Pivot is the first frame manufacturer to feature the 92mm wide bottom bracket shell standard, originally developed in conjunction with Shimano XTR. With the press fit 92 system, there are no external washers or threads in the shell. The bearings are housed in light composite resin cups with a full sealed sleeve to keep out the elements. This design allows for easy crank installation, with no frame facing or special spacers required. Chain line is perfectly optimized and as an added advantage, the bearings are extremely easy to replace. Another bonus is that the XTR version includes a 3 year warranty from Shimano. The system works with Shimano, FSA and Race Face cranks (all compatible with the Shimano cup design) as well as the SRAM GXP system for which SRAM offers both standard and ceramic versions. In addition, Enduro and several other aftermarket companies offer both replacement bottom brackets and bearings to support every major crank brand.

Are there any other bottom brackets that will work with the Mach 4 Carbon? Can you upgrade to ceramic bearings?

We use a Press Fit 92 BB (sometimes called PF92 or BB92) design. Almost every crank and BB manufacturer offers a bottom bracket that is compatible with the Press Fit 92 system. Enduro, SRAM, FSA and others all offer ceramic bearing options.

What is the narrowest Q factor crank that the Mach 4 Carbon will accept?

The Mach 4 will accept cranks with a Q factor measurement as low as 156mm (Such as the narrower option in the SRAM XX1 or the new XTR Race crank). Of course, anything greater than 156mm will work as well. Most standard MTB Q factor measurements are at 163mm.

What hub/wheel spacing does the Mach 4 Carbon use?

The Mach 4 Carbon uses the 142mm X 12mm hub/wheel spacing. Our custom 12mm DT Swiss axle is included with the frame. The axle is based off of Shimano’s 12mm through axle specifications for length and thread pitch so if you were ever to lose your axle, a Shimano or Shimano compatible axle will work properly as well.

What size seatpost does the Mach 4 Carbon use?

The Mach 4 frame uses a 30.9mm seatpost.

What size seat clamp does the Mach 4 Carbon use?

The Mach 4 frame uses a 34.9mm or 35mm (as some manufacturers call it) seatpost clamp.

Can I use a dropper post with this frame?

Yes, both internally and externally-routed dropper posts are compatible with the Mach 4 Carbon frame.

What front derailleur does the Mach 4 Carbon use?

The Mach 4 Carbon, we use a DM (direct mount) style front derailleur. You can use a SRAM direct mount top pull X-9 or XO version for any 2X system. The SRAM top pull is best if you are running a 10 speed rear cassette and a large front chainring smaller then a 38 tooth. If you are running a 2X or 3X Shimano system with 10 speed rear cassette then use a Shimano direct mount FD. We specify a top pull on the Mach 4 but their dual pull models will work as well. If you are running Shimano’s new 11 speed XTR rear cassette then we recommend the new direct mount XTR side-swing FD. The new XTR side-swing F/D also works incredibly well on current Shimano 10 speed rear cassette systems when mated with any Shimano XT or above left shifter and a 2X front with 36 tooth or small big ring. It is the only Shimano front derailleur that can really be used with front gear combinations such as 36/24, 36/22, 34/24, and 34/22.

What headset do I need for the Mach 4 Carbon?

The Mach 4 Carbon uses a ZS (zero stack) 44mm top and (zero stack) 56mm bottom, or a Chris King Inset 2.

Can I run a large water bottle in the front triangle on the Mach 4Carbon?

Yes, the Mach 4 carbon was designed to clear a large water bottle on top of the down tube. For best clearance, we suggest removing the rear shock and swapping the spacer hardware from front to rear. Re-install the shock with the air can side facing the rear triangle and the CTD adjusters facing down, away from the top tube. This will open up the clearance significantly at the front, allowing easy access to larger bottles. This is the setup that all of our racers run, and we designed the frame to be run with a flipped shock for those wanting to use large bottles.

We also include a spacer to be placed under the upper water bottle cage mount that changes the angle of the water bottle cage enough to provide the extra clearance required to prevent a large water bottle from rubbing against the down tube.

m4c-flipped-shock

How wide of a tire can I run on the Mach 4 Carbon?

We use the Maxxis Ardent Race 2.2 in our complete bike builds. However, the Mach 4 Carbon is designed to easily accept most 2.3 tires in the market. For instance, a Maxxis High-Roller II 2.3 fits with plenty of clearance. For other 2.35 tires in the market, some may fit, but rim width and tire manufacture sizing call outs and tire inconsistency can result in huge difference among both tire brands and individual tires. For anything beyond a 2.3, we suggest you check the fit with your chosen rim and tire combination to make sure it has proper clearance before riding.

How large of a rotor will fit on the Mach 4 Carbon?

The Mach 4 Carbon will clear either a 160mm or 180mm rotor.

What type of rear brake adapter do I need?

No brake adapter is needed for a 160mm rotor. However, many manufacturers make adapters for larger rotor sizes, in which case you would need a 160mm direct mount/ post to post adapter.

What travel fork can I use on my Mach 4 Carbon?

The Mach 4 was designed for either a 100mm or 120mm fork. We use a 120mm fork in all our complete bike builds (although for special orders you can request a 100mm). The maximum travel length that can be used on the Mach 4 is 130mm travel.

What is the fork offset on the Mach 4 Carbon?

We use a Fox 120mm, 34 forks with a 44mm offset in all our complete bike builds. The 100mm travel special order option also features 44mm offset.

What is the eye-to-eye shock length and stroke length on the Mach 4 Carbon?

For the small, medium and large Mach 4 Carbon frames, the eye-to-eye shock length is 7.25 inches and the stroke length is 1.75 inches. The size x-small frame has an eye-to-eye shock length of 6.5 inches and the stroke length is 1.5 inches.

If I want to run a different brand of shock on my Mach 4 Carbon, what else do I need to know?

The Mach 4 shock uses M8 through bolt hardware on both the front and rear. Shock spacer dimensions are 22mm wide front and 36mm wide rear. The frame is designed around a standard size air can volume and we typically run light to medium valving on the compression side (depending on rider weight) and light rebound damping.

What are the torque specs?

A detailed PDF of the torque specs can be found under the "Tech Specs" tab.

Why does the Size X-Small feature 100mm of travel?

In order to optimize the Mach 4 X-small size, we arrived at 100mm of travel for the best combination of stand-over clearance, overall frame fit, and shock tuning for the target weight and height riders that the Mach 4 X-small frame is designed for.
