The race proven, World Cup‐caliber, Mach 429SL Carbon is the leader of the new breed of racing full suspension. Choice of National and World Champions, selected as Best Mountain Bike at Interbike and as Mountain Bike of the Year by Bicycling Magazine, Pivot’s 100mm 29er is the bike you want for the ultimate in power transfer efficiency and technical trail mastery.

Pivot Carbon Technology

To create Pivot’s premier racing chassis, we begin by engineering for the ideal lay‐up structures, tube sections and composite materials choices, and then utilize our proprietary hollow core internal molding process to bring this best‐in‐class frame to life. This newest, even lighter, version of the Mach 429 SL Carbon features an all new Boost™ rear triangle, for a significant increases in both frame and wheel stiffness over what was already one of the stiffest, lightest and strongest cross country bikes in the world. For those seeking the top of the line in components and compatibility, the Pivot Mach 429SL Carbon is fully Di2 integrated and internal dropper post compatible via Pivot’s Cable Port System. Internal routing for any component is easy to install and maintain via large, easy to access ports and interchangeable covers. Riders have the ability to switch between a variety of cable routing options, allowing for the cleanest possible installation of wires, batteries and cables. No matter what components or gearing you choose, now or in the future, we have you covered.

New School Racing Geometry

The race winning Mach 429SL Carbon geometry is tried and tested at tested at the biggest events in the world. On the uphill, you benefit from the latest in dw‐link® suspension design with a Fox Float DPS Kashima Factory shock, performance‐tuned specifically for the Mach 429SL Carbon. You can expect the kind pedaling efficiency our National Champions demand, provided by dw‐link®’s anti‐squat characteristics, instant acceleration and unparalleled climbing traction.

dw-link™ and Fox Factory Suspension

Mach 429SL Carbon is spec’d with the Fox Float DPS (Dual Piston System) shock custom tuned specifically for XC and Endurance racing. 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’s® patented position‐sensitive anti‐squat, gives riders even better traction on steep ups and over rough trail.

Downhill, the 100mm of dw‐link® suspension performs like a longer travel bike, especially when combined with the precision of the new 12x148mm rear end, and the rollover qualities of the 29inch wheel – giving athletes the advantage in technical terrain and inspiring record‐setting descents.

To match the rear suspension, we’ve spec’d the Mach 429SL Carbon with a 120mm Fox 34 Factory fork, with a FIT 4 3‐postion damper for fine tuning performance to your exact specifications.

All the Right Details

Other essential details include post mount disc brake mounts for easy set up and weight savings, stealth dropper compatibility and Enduro Max cartridge bearings throughout. We’ve got clearance for 2 water bottles in every size, and great new graphics that are sure to coordinate perfectly with the best components, build kits, and your team kit.

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 the only thing you need to think about is the ride.

Product Reviews

"The efficiency that the DW link suspension gives my Mach 429SL Carbon has made me really fall in love with racing and riding a full suspension bike. I used to always choose a hardtail, but the Mach 429SL Caron climbs stiff enough while still allowing plenty of traction, and has improved my ability for max speed while descending some of the most technically challenging courses."

- Rose Grant & the Mach 429SL Carbon

Chloe Woodruff & Rose Grant aim high on the World Cup

02.01.2017 | News

"As two of the nation’s top XC racers, Chloe Woodruff and Rose Grant’s work lives cross over into their personal lives. How could it be otherwise? But the race to the finish is not so much about that one second when they cross the line. Rather, these two women live each day as champions." Pivot Cycles is proud to sponsor two of the fastest women in mountain biking. Between the two of them, they race on...

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:

Small: 5'4" – 5’9”
Medium: 5'9" – 6’1”
Large: 6'1" – 6’4”
X-Large: 6'3" +

How do I set the sag on my Mach 429 SL?

We make it easy to get the best ride out of your Pivot bike with a simple sag indicator already installed on your bike, and this follow-along video featuring our own Bernard Kerr:

https://vimeo.com/pivotcycles/sag

What hub/wheel spacing does the Mach 429SL use?

The Mach 429SL uses the Boost 148mm X 12mm hub/wheel spacing. This is a new 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

What size wheels can I run on the Mach 429 SL Carbon?

The Mach 429SL Carbon is compatible with both 29” and 27.5”+ wheelsize

How wide of a tire can I run on the Mach 429SL Carbon?

The Mach 429SL Carbon fits 29” tires up to 2.35” and 27.5”+ tires up to 2.8”

Can I run a large water bottle on the Mach 429SL Carbon?

Yes, the Mach 429SL 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.

What is the thread pitch on the rear axle?

Pivot uses a 1.5 thread pitch on the rear thru axle. You can order one through our online store here:

http://www.pivotcycles.com/store/index.php?route=product/product&path=60&product_id=132

What size seatpost does the Mach 429SL Carbon use?

The Mach 429SL Carbon frame uses a 30.9mm seatpost.

What size seat clamp does the Mach 429SL Carbon use?

The Mach 429SL Carbon frame uses a 34.9mm or 35mm (as some manufacturers call it) seatpost clamp.

Can I use a dropper post with this frame?

The Mach 429SL is designed for internal routing dropper post so any internal routed dropper post is compatible with the 429SL frame.

What cranks and bottom bracket will the Mach 429SL accept?

The Mach 429SL will accept all cranks designed for the BOOST system and compatible with a press fit 92mm bottom bracket. BOOST system means that the rear hub spacing is 148mm and the chain-rings have been shifted out approximately 3mm from where a tradition crank designed for a 142mm rear hub would be so that the chainrings will line up properly with the new position of the cassette on the 148mm rear hub

Can I run non-Boost™ cranks on my Mach 429SL?

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 429SL 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 429SL is also shifted outwards to accommodate the BOOST design.

What front derailleur does the Mach 429SL Carbon use?

The Mach 429SL Carbon uses a DM (direct mount) Shimano side-swing style front derailleur only. Shimano produces the side-swing front derailleur in Deore and SLX for 10 speed drivetrains and in SLX, XT and XTR for 11 speed drivetrain

What is the maximum size chain ring I can put on my Mach 429SL Carbon?

The maximum size chain ring that will clear on the Mach 429SL Carbon is a 34-tooth.

Can I mount a chain guide on my Mach 429SL Carbon?

Yes. The Mach 429SL carbon features ISCG05 mounts on the frame. Most upper guides on the market will fit. For full upper and lower guides, you will need a wide angle design.

What headset do I need for the Mach 429SL Carbon?

The Mach 429SL Carbon uses a ZS (zero stack) 44mm top and (zero stack) 56mm bottom, or a Chris King Inset 2.

How large of a rotor will fit on the Mach 429SL Carbon?

The Mach 429SL 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 429SL Carbon

The Mach 429SL Carbon 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 429SL Carbon is 130mm travel.

What is the fork offset on the Mach 429SL Carbon?

We use a Fox 120mm, 34 forks with a 51mm 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 429SL Carbon?

The eye to eye shock length is 7.25 inches and the stroke length is 1.75 inches

If I want to run a different brand of shock on my Mach 429SL Carbon, what else do I need to know?

The Mach 429SL 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.

Can I put a coil-over shock on my Mach 429SL Carbon?

You cannot run a coil-over on your Mach 429SL Carbon! The Mach 429SL 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 429SL requires. Running a coil-over shock on the Mach 429SL 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.
