The half pound lighter Pivot Mach 429SL Carbon is the bike that you need when the course tests both your engine size and your handling skills. Dominate in any event with the newest version of our award winning 100mm 29er – a perfect combination of incredible racing efficiency and trail-worthy technical prowess.
The space age chassis drops over 1/2lb (226g) via the use of leading-edge carbon fiber and our proprietary hollow-core, internal-mandrel process. This coveted production technology enables us to create best-in-class frames with the “lighter, stiffer, stronger” qualities that put the Mach 429SL Carbon at the top of the list.
To achieve a huge reduction in weight and an increase in frame stiffness, our engineers looked for every possible advantage via optimizing the composite materials and lay-up structure in the 429’s huge, box-section downtube and bottom bracket area. From the tapered head tube to the highly-specific oversize rear triangle tube sections, nothing was left untouched when we made the Mach 429SL Carbon frame the lightest 29er chassis – with the best power transfer – available today.
For those seeking the top of the line in components and compatibility, the Pivot Mach 429SL Carbon is only the second production mountain bike in the world to be fully Di2 integrated (the Pivot Mach 4 Carbon being the first). Featuring 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. Rest easy knowing that no matter what components or gearing you choose, now or in the future, we have you covered.
Our race-winning, trail-slaying Mach 429SL Carbon geometry is tried, tested and confidence-inspiring. On the uphill, you benefit from the latest in dw-link® suspension design with a Fox Float Kashima Factory shock, performance-tuned specifically for the Mach 429SL Carbon. You can expect World Cup level efficiency provided by dw-link®’s anti-squat characteristics, instant acceleration and unparalleled climbing traction.
Downhill, the 100mm of dw-link® suspension performs like a longer travel bike – an incredibly capable ride in technical terrain and ready for record-setting descents, enhanced by the precise feel of 12 x 142mm rear spacing and the rollover qualities of the 29 inch wheel.
The Mach 429SL Carbon is designed to work with 100 to 120mm forks, allowing for perfect rider optimization – shorter for your cross country weapon, longer for the ultimate in trail-handling.
Our mountain bikes feature the PF92 bottom bracket. Collaboratively developed by our engineers and Shimano, this allows for wider pivots and better bearing support, both of which contribute to increased frame stiffness and strength.
Other essential details include post mount disc brake mounts for easy set up and weight savings, direct mount front derailleur for perfect shifting, stealth dropper compatibility and Enduro Max cartridge bearings throughout. Our 429SL frame will accommodate two water bottles of any size and boasts updated graphics for a sleek, race-inspired look.
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.

"I ride my Mach 429SL Carbon on a lot of technical desert XC trails in Colorado. Since getting the bike, I've set my fastest times ever! I love this bike. I ride a size small and am 5'6"."
"I’ve ridden many different bikes from several of the major brands and struggled to find a “one quiver” bike that would let me climb the northern Utah single track well and also be able to ride the chunkier southern Utah trails in Moab and St. George….without getting too beat up. I’ve finally found that bike! It climbs like a hardtail 29er, corners like a 26er, and charges through the chuck like a longer travel trail-bike. I just built my 429 up a few weeks ago and it’s been amazing on the local single track in Salt Lake City, but the true test was this past weekend in Moab on Porcupine Rim. I’ve ridden that trail on a lot of different bikes, and while many people would probably prefer a longer travel bike for that particular trail, I was blown away with how amazing my “green machine” did. Thanks for building the most solid bike I ever ridden; looking forward to many more happy miles!"
"Here’s a race update on my first experience on the 429 SL ... My first race was last Saturday in St. George Utah at the Cactus Hugger. A mix of double track and rocky technical climbs with several rock –drop type descents. What I noticed was how stable the bike was at every section and feature of the course. Even towards the end when I was getting tired, the bike went over obstacles that a lesser full suspension may have stopped dead in its tracks due to a more shallow suspension movement. I placed 4th and look to racing again at The Rumble at Road 18 in Grand Junction in a few weeks.
I'm 5'10" and ride a size medium in both the 429SL and the LES 29. "
Aaron Gulley is Outside Online's premier bike tester - he rode the Mach 429SL Carbon for six months and had this to say:
"It’s svelte enough to take on an XC World Cup course, but also plenty compliant and confident to deal with steep, rubble-choked chutes and full-on rock obstacles. On one of the burliest trails in Santa Fe, which had me walking in the past on short-travel bikes, I was able to roll...

James Huang took the Mach 429SL to the Breck Epic and loved the performance both up and downhill:
"...the Mach 429SL was gloriously efficient under power with almost no bob even without the electronic rear lockout engaged."
"I regularly took the ugly line down wider sections of trail to get around fellow racers who were taking more conservative routes and gleefully jumped, hopped, and slid up and around...
"While geometry remains the same, new hollow-core carbon technology increases stiffness and
shaves half a pound off the previous carbon frame, now 5.3 pounds including the shock. Match that to
100mm of potent dw-link-controlled suspension and this venerable favorite becomes even more
attractive." Get all the details here: Dirt Rag Review: Pivot Mach...

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: 5'5" – 5’10”
Medium: 5'9" – 6’1”
Large: 6'1" – 6’4”
X-Large: 6'3" +
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.
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.
The Mach 429SL 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.
The Mach 429SL 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.
The Mach 429SL Carbon frame uses a 30.9mm seatpost.
The Mach 429SL Carbon frame uses a 34.9mm or 35mm (as some manufacturers call it) seatpost clamp.
The Mach 429SL is designed forinternal routing dropper post so any internal routed dropper post is compatible with the 429SL frame.
The Mach 429SL 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.
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, the two chain guides we found that fit best are the Blackspire Twinty2x, ISG05/36T - 40t and the 32 - 36t.
The Mach 429SL Carbon uses a ZS (zero stack) 44mm top and (zero stack) 56mm bottom, or a Chris King Inset 2.
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.
We use the Maxxis Ardent Race 2.2 in our complete bike builds. However, the Mach 429SL 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 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.
The Mach 429SL Carbon will clear either a 160mm or 180mm rotor.
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.
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.
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.
The eye to eye shock length is 7.25 inches and the stroke length is 1.75 inches.
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.
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.
