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" +

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

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.

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).

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

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.

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

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.

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

30.9mm

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

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

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

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.

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.

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

180mm

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.

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.

51mm

Eye-to-eye: 7.25"

Stroke: 1.75"

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.

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.
