Trailbike perfection.

The Mach 5.7 Carbon has a long history as our most popular model. It’s the bike that the majority of us at Pivot personally own and it’s the bike that can take you anywhere and allow you to ride just about anything. The 5.7C provides stable handling and supreme confidence in technical riding while the dw-link’s® patented position-sensitive anti-squat keeps the bottom bracket from lowering (squatting) under power and the head tube from slacking on climbs, making for a precise and agile climbing machine. With 5.7” (145mm) of dw-link® suspended travel in 26” wheel form and 5.2” (133mm) with the new 27.5” conversion, the 5.7 Carbon has become even more capable in a wider variety of terrain while the 5.7’s carbon chassis adds a higher level of enjoyment to every ride.

Mach 5.7 Carbon Features

  • Pivot-exclusive hollow box, high-compression internal mandrel technology allows for greater compaction and smoother internal walls resulting in a lighter, stronger, highly optimized frame design with the best stiffness to weight ratio in the class.
  • 5.7”(145mm) with 26” wheels or 5.2”(133mm) travel with the new 27.5” conversion. The dw-link® suspension design features position-sensitive anti-squat allowing us to achieve the stable handling and increased cornering benefits of a lower bottom bracket with more travel, all with better pedaling efficiency and a plusher feel.
  • Pivot-specific, custom tuned Fox Float CTD shock technology: increased performance and adjustment range allows riders to quickly and easily adjust for changing course or ride conditions.
  • Under top tube shift cable routing with clean disc brake and dropper seat post routing.
  • Rubberized leather chainstay, inner seat stay, and down tube protectors for a quiet ride and higher impact resistance.
  • Available in four color options - Natural Carbon/Green, Natural Carbon/Blue, Natural Carbon Red, Natural Carbon/Pink (Pink available in XS & Small sizes only)

Latest Mach 5.7 Review in Dirt Rag

02.17.2014 | Online Media

SEE THE WHOLE STORY: http://dirtragmag.com/review-pivot-mach-5-7-carbon/ One bike to do it all—that’s the idea behind Pivot’s Mach 5.7.

Cycles Bespoke Mach 5.7 Carbon Review

10.24.2012 | Online Media

"I suppose, to summarize the 5.7, I would say it perfectly represents the modern interpretation of a mountain bike. It manages to excel on virtually any type of terrain and gives the impression of being several bikes all wrapped into one. It can flow through twisty singletrack,  dole out grins by the bucket load when pointing down, and it can unerringly get you back to the top to do it all over again. And in...

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: 4'11" – 5’5”
Small: 5'5" – 5’9”
Medium: 5'9” – 6’
Large: 5’11” – 6’2”
X-Large: 6'2” +

What bottom bracket is used on the Mach 5.7 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 5.7 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.

What is the narrowest Q factor crank that the Mach 5.7 Carbon will accept?

The Mach 5.7 Carbon 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 5.7 Carbon use?

The Mach 5.7 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 5.7 Carbon use?

The Mach 5.7 Carbon frame uses a 30.9 seatpost and a 34.9 35mm (as some manufacturers call it) seatpost clamp.

Can I use a dropper post with this frame?

Yes, any dropper post with external routing will work on this frame.

What front derailleur does the Mach 5.7 Carbon use?

The Mach 5.7 Carbon uses 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. You will need to look at Shimano’s technical specifications in order to source the correct Shimano top pull DM front derailleur for the front chainring combination you are using.

What headset do I need for the Mach 5.7 Carbon?

The Mach 5.7 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 on the Mach 5.7 Carbon?

Yes, the Mach 5.7 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 and then re-installing the shock with the air can side facing the rear triangle and the CTD adjusters facing up towards the top tube. This will open up the clearance significantly at the front allowing easy access to the larger bottles. This is the set up all our racers run and we designed the frame to be run this way for those wanting to use large bottles.

How wide of a tire can I run on the Mach 5.7 Carbon?

In the 26” wheels version, you can run most 26” X 2.3” tires on the market. With the 27.5” conversion, we use the Maxxis Ardent Race 2.2 in our complete bike builds. With the 27.5” conversion, vertical tire clearance is somewhat limited so although there may be some larger tires that fit, rim width and tire manufacture sizing call outs and tire inconsistency can result in huge difference among both tire brands and individual tires. On the 27.5” conversion bike, if you are running anything other than our recommended specification, we suggest you check the fit with your chosen rim and tire combination to make sure it has proper clearance before riding. Wider rims can allow the use of a slightly bigger tire diameter in some cases.

How large of a rotor will fit on the Mach 5.7 Carbon?

The Mach 5.7 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 5.7 Carbon?

All Mach 5.7 frames are approved for use with 140-160mm travel forks. However, it is our experience that the geometry and handling perform best with a fork that has between 140 and 150mm of travel. We have tested the Fox 34 in both 150mm and 160mm configurations and vastly prefer the 150mm setting to maintain proper BB height, head angle, seat angle and the overall suspension balance of the bike so for those using a Fox 34 fork, this is our recommended set up. For our complete builds with the 26” Mach 5.7, bikes ship with a 150mm fork. With the 27.5” conversion, the builds come with a 27.5” X 140mm travel to maintain proper geometry and match the 27.5” bike 5.2” of rear travel more equally.

What is the eye-to-eye shock length and stroke length on the Mach 5.7?

The eye-to-eye shock length is 7.875 inches and the stroke length is 2.25 inches for the 26” wheel version and 7.875 inches and the stroke length is 2.00 inches for the 27.5” wheel conversion

If I want to run a different brand of shock on my Mach 5.7 Carbon, what else do I need to know?

The Mach 5.7 Carbon 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 high volume air can for the 26” wheel version and standard size air can volume for the 27.5” option. We typically run light to medium valving on the compression side (depending on rider weight) and light rebound damping.

Can I put a coil-over shock on my Mach 5.7 Carbon?

You cannot run a coil-over on your Mach 5.7 Carbon! The Mach 5.7 Carbon was designed to work with the progressiveness of an air spring. A coil-over shock (even one with separate bottoming control) does not offer the progressive spring curve that the Mach 5.7 requires. Running a coil-over shock on the Mach 5.7 will result in hard bottoming and damage to the frame.

What are the torque specs?

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