MACH 429 TRAIL DETAILS

THE PERFECT ALL-ROUNDER

The greatest trail bikes do everything well, no matter what or where you ride. Our goal when designing the Mach 429 Trail was to create a new category of trail bike – one that takes advantage of the best features of 29 and yet maintains the performance characteristics that make you forget about wheelsize and, instead, translate to the “best-ride-ever,” every time you ride.

TUNED FOR THE TRAIL

The Mach 429 Trail’s dw-link® suspension drives a custom-tuned Fox Float DPS (Dual Piston System) shock, which gives the rear suspension an incredibly plush feel with a wide range of damping control. The Fox DPS shock also offers an extremely positive “firm” position that makes easy work of long fire-road climbs. To match the Mach 429 Trail’s deep-feeling rear suspension, we’ve equipped each model with a 130mm Fox 34 suspension fork.  Combined, these features make the Mach 429 Trail an up-trail-conquering, climbing machine with a nearly bottomless feel in even the most aggressive terrain.

A PERFECTLY BALANCED CHASSIS

The best trail bikes are neither whippy nor overbuilt. They are, in a word, balanced. We sweat the details—painstakingly developing the right mix of resins, composite fibers, lay-orientation and frame shaping to create a chassis with the perfect blend of strength and stiffness. Effortless handling, incredible power transfer and precise cornering are what make the Mach 429 Trail capable of being that elusive “one-bike quiver”.

MID-TRAVEL WEIGHT, BIG-HIT TRAITS.

The Mach 429 Trail marks the introduction of Pivot’s mid-travel trail linkage, designed specifically for trail bikes. Drawing major influences from the Phoenix DH Carbon and Mach 6 Carbon, the 429 Trail utilizes an entirely new upper linkage to provide the same ultra-precise control and bottomless feel of our longer travel dw-link® designs in a more compact, lighter package for trail applications. When we pair the new upper linkage with the same lower linkage design that we utilize on the Mach 6 Carbon, what you get is a bike you can take anywhere and over anything – an incredibly versatile 29er with seemingly endless suspension and noticeably increased traction. 

FAQS

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" – 5’8”

Medium: 5'7" – 5'10”

Large: 5'10" – 6’2”

X-Large: 6'2" +

How do I set the sag on my bike?

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 bottom bracket do I need and what 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.

Can I use a non-Boost crankset?

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 429 trail 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 429 Trail 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).

Can I run a triple crank on the Mach 429 Trail?

You cannot, it is designed for only 1x (single) and 2x (double) front chainring combinations.

What front derailleur does the Mach 429 Trail use?

The Mach 429 Trail uses an e-type Shimano side-swing style front derailleur only. Shimano produces the new e-type side-swing front derailleur in Deore and SLX for 10 speed drivetrains and XT and XTR for 11 speed drivetrains.

Can I mount a chain guide on my Mach 429 Trail?

Yes. The Mach 429 Trail features ISCG05 mounts on the frame. Most upper guides on the market will fit.

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

The Mach 429 Trail 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 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.

What size seatpost does the Mach 429 Trail use?

30.9mm

What size seat clamp does the Mach 429 Trail use?

34.9mm or 35mm (as some manufacturers call it)

Can I use a dropper post with this frame?

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

What headset do I need?

Zero stack (ZS) 44mm top and ZS 56mm bottom, or a Chris King Inset 2

Can I run a water bottle on the Mach 429 Trail?

Yes, the Mach 429 Trail was designed to clear a large water bottle on top of the down tube. For best clearance, we suggest removing the front bolt of the rear shock and then rotate the air can so the adjusters are facing up towards the top tube. This will open up the clearance at the front allowing easy access to the larger bottles. We designed the frame to be run this way for those wanting to use large bottles with maximum clearance.

How wide of a tire can I fit on the Mach 429 Trail?

We use the Maxxis Ardent Race 2.2 in our complete bike builds. However, the Mach 429 Trail 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 2.35-2.4 29er tires in the market, most should 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.

Can I run 27.5"+ wheels on my Mach 429 Trail?

Yes, this bike will accomodate 27.5+ tires in 2.8" (WTB) with up to 40mm (inner) rims.

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

180mm

Do I need a rear brake adapter?

No brake adapter is needed for a 160mm rotor. However, many manufacturers make adapters for 180mm rotor sizes, in which case you would need a 180mm direct mount/ post to post adapter.

What travel fork can I use?

The Mach 429 Trail was designed for a 120- 130mm fork. We use a 130mm fork in all our complete bike builds. The maximum travel length that can be used on the Mach 429 Trail is 140mm travel.

What is the fork offset?

51mm

What is the eye-to-eye shock length and stroke length?

Eye-to-eye: 7.25"

Stroke: 1.75"

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

The Mach 429 Trail shock uses M8 through bolt hardware on both the front and rear. Shock spacer dimensions are 22mm wide front and rear. The standard FOX shock runs their small volume EVOL can. For other brands of air shocks, this would typically be a standard size air can volume. Most higher volume air cans (FOX EVOL or otherwise) will not clear the rocker (nor would they provide for an optimal spring curve). We typically run light to medium valving on the compression side (depending on rider weight) and medium rebound damping.

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

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