Mach 6 Carbon

We suggest that you pick your Mach 6 size based on your riding style. The Medium, Large and X-Large Mach 6 features enduro/trail bike long and low geometry with both shorter seat tube and head tube measurements per size – this geometry means that most riders can go up or down a size and should base their choice on riding-style, reach and stem length preferences. For shorter riders already running short stems, the Mach 6 X-Small and Small sizes feature rider size appropriate reach and geometry to make sure that your Mach 6 handles perfectly for you. Be sure to also consult our dropper post fit guide when making your selection. You can always reach out to us on Live Chat for additional guidance.

Mach 6 Carbon Sizing Recommendations:

X-Small: 4'11" – 5’4”
Small: 5'3" – 5’6”
Medium: 5'6” – 5’11”
Large: 5'10” – 6'3”
X-Large: 6'2” +

The Mach 6 Carbon features a low stand-over height and short seat tubes to allow the use of longer travel dropper posts and/or more flexibility for a wider range of rider sizes.

There are some limitations that each dropper post can accommodate for each frame size based on the individual rider’s saddle height, so it is important to check fit before choosing the travel and model of dropper post for your Mach 6 Carbon. Use the Dropper Fit Guide under the Tech Specs section to find the right length post for your bike.

Variables in frame size, discrepancies in scale calibrations, and method of weighing (with or without pedals and such) all lead to inaccurate comparisons, so we choose not to publish our bike weights. Pivot bicycles are among the lightest available, but the weight is only one of many factors that make a great bicycle. Other aspects such as frame stiffness, strength, durability, and ride quality are just as important as weight to our engineers when designing our Hollow Core Carbon and aluminum frames. Instead of comparing grams online, we suggest you visit your local Pivot dealer and see our attention to detail, smart, high value spec, and class leading features. Bring a scale if you’d like, but take just one demo ride and you’ll feel why Pivot Cycles are the most well-rounded, highest performing bicycles on the market and in many cases, yes, it’s the lightest as well.

We make it easy to get the best ride out of your Pivot bike with a simple sag indicator already installed on your bike. Please consult our suspension set up guide and/or this follow-along video featuring our own Bernard Kerr:

Yes, the Mach 6 Carbon features two sets of water bottle cage mounts on the medium to x-large frames - one on the top of the down tube and the other is underneath the down tube. 

On the small and x-small frames, there is one bottle cage mount underneath the down tube.

The Mach 6 Carbon uses the Boost 148mm X 12mm hub/wheel spacing. This is a hub design with wider flanges so you cannot take a current 135mm, 142mm, 150mm, or 157mm hub and change end caps to convert an existing hub.

Pivot uses a 1.5 thread pitch on the rear thru axle. This is the same thread pitch and axle length as the Shimano Boost 148mm x 12mm through axle.

The Mach 6 Carbon frame uses a 30.9mm seatpost.

The Mach 6 Carbon frame uses a 34.9mm or 35mm (as some manufacturers call it) seatpost clamp.

XS  - 160mm

S - 190mm

M - 210mm

L - 235mm

XL - 275mm

*Please check seat post measurements carefully before installing the post.

Yes. The Mach 6 Carbon features ISCG05 mounts on the frame. Most upper guides on the market will fit and you can either use the ISCG05 mounts or some of the more compact versions that attach to an E-Type front derailleur mount. For full upper and lower guides, we recommend the MRP AMG for the Mach 6 Carbon.

The Mach 6 Carbon uses an e-type Shimano side-swing style front derailleur only. Shimano produces the e-type side-swing front derailleur in Deore and SLX for 10 speed drivetrains and XT and XTR for 11 speed drivetrains.

The Mach 6 Carbon was designed for a 160mm fork. The maximum travel length that can be used on the Mach 6 Carbon is 170mm travel.

The fork offset on the Mach 6 Carbon is 44mm.

The Mach 6 Carbon can run 27.5” tires up to 2.6” inches.

The Mach 6 Carbon uses a ZS (zero stack) 44mm top and (zero stack) 56mm bottom, or a Chris King Inset 2.

The Mach 6 Carbon was designed for a 180mm rotor and features a 180mm post mount design so you cannot fit a 160mm rotor on the Mach 6 Carbon frame.

No brake adapter is needed for a 180mm rotor. However, if you'd prefer to run a 203mm rotor, you would need a proper direct mount/post to post adapter to go from a 180mm to 203mm rotor.

The Mach 6 Carbon will accept all cranks designed for the BOOST system and compatible with a press fit 92mm bottom bracket. BOOST means that the rear hub spacing is 148mm and the chain-rings have been shifted out approximately 3mm from where a traditional crank designed for a 142mm rear hub would be. This allows the chainrings to line up properly with the new position of the cassette.

In some cases you can run a conventional non-BOOST 1X or 2X crank. The Race Face NEXT 1X and other Cinch system 1X cranks are dual compatible between standard 142mm and 148mm Boost rear ends. Some smaller chainring combination 1X (30 and 32T) Shimano XT and XTR 11 will also work. In some cases 2X standard cranks may also work with 24/34, 26/36, and 22/36 combinations. Shimano’s new 11 Speed XTR and XT standard cranks feature both 24/34 and 26/36 chainring options, which work perfectly with the Mach 6 Carbon frame as Shimano’s chainline dimensions already tend to run wider than others in the market. There may be other 2X non- boost cranks available that will work although it is dependent on specific chainline and chainring size. If the chainline is not out far enough, the front derailleur clearance may be tight when shifting into the small ring as the front derailleur mount on the Mach 6 Carbon is also shifted outwards to accommodate the BOOST design.

Additionally, you cannot run cranks designed specifically with a narrower Q Factor such as XTR Race 158mm Q factor crank and the SRAM XX1 156Q crank (In fact, for any SRAM 1X cranks, you need to run their specific BOOST version of the crank).

The Mach 6 Carbon will accept cranks with a standard Q factor measurement as low as 163mm. You cannot run cranks designed with a narrower Q Factor, such as XTR Race 158mm or the SRAM XX1 156mm.

The Mach 6 Carbon uses a Press Fit 92mm BB. Some bottom bracket manufacturers may refer to it as BB92 or PF92 as well. Every crank manufacture offers Press Fit 92mm BB options.

The eye-to-eye shock length is 8.5 inches and the stroke length is 2.5 inches.

The Mach 6 Carbon shock uses M8 through bolt hardware on the front and no hardware on the rear. Shock spacer dimensions are 22mm wide front. On the rear of the shock, the spacer hardware and bushing will need to be removed as the strut mounts directly to the shock body. Some shocks may have a different spec then the Fox shock (that the Mach 6 Carbon is designed for) and may not fit properly. Also, as we cannot test every shock on the market, riders assume some risk if they choose a shock that does not fit properly or is not tuned correctly for the bike. The frame is designed around a large volume air can. We run medium compression valving and medium rebound damping.

Yes, as long as you order the correct eyelet size (15mm eyelet). Additionally, the fit of the Cane Creek shocks into our strut is not as precise as that on the Fox shocks so extra care needs to be taken to make sure that the shock is not able to rotate or move in the strut as any sideways movement during riding can damage the frame.

The Mach 6 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 6 Carbon requires. Running a coil-over shock on the Mach 6 Carbon will result in hard bottoming and damage to the frame. Any frame damage occurring due to issues related to any shock that is not what is supplied with the bike or offered as an upgrade for the Mach 6 through Pivot Cycles will not be covered under warranty.
