Pivot's approach to the Pivot Mach 429 Trail Pro X01 Complete Mountain Bike was a bit of a Frankenstein affair, pulling inspiration from bikes as far apart in intended use as the 429SL, the Mach 6, and the DH-specific Phoenix. The result is a 29er that, when stitched together with FOX's trail suspension kit and brought to life with a jolt of SRAM one-by, manages to simultaneously haunt the worlds of XC and enduro, hitting the marks for a quiver-killing trail bike.

The 429 Trail's DW-Link suspension owes its spooky capabilities to a handful of queues taken from the Mach 6 and Phoenix, teasing a depth out of the 116mm travel that feels closer to a proper five-inch trail bike. The canny cyclist may spot elements of Pivot's DH clevis and enduro lower linkage in this model, but the completely new upper linkage translates those big-hit designs to the traction-focused language of a trail bike. By bringing the 429SL's small-bump compliance and race-worthy trail-contact into conversation with the Mach 6's terrain-erasing capabilities, the 429 Trail defines the crossroads where XC speed meets fearless, enduro aggression.

The frame itself begins life with Pivot's hollow-core internal molding process for uniform, controlled wall thicknesses and material distribution. This process virtually eliminates inconsistencies and resin pooling, increasing structural integrity while targeting areas for weight loss. The frame rises from the mold with a 67.5-degree head tube and relatively stubby chainstays, making it slack enough to challenge lines across rock gardens but nimble enough to pick its way through enduro-grade terrain — all while sticking climbs and roosting berms in the manner that made us fall in love with its immediate predecessor, the 429SL.

Pivot teamed with Shimano to design a bottom bracket shell that meshes seamlessly with the Japanese firm's PF92 standard. The wide bottom bracket anchors the unbelievably stiff Boost 148/110 axles, accommodating wider pivot placement for longer life in the suspension's bearings and a stiffer rear triangle. We suspect that the PF92/Boost 148 collaboration is also responsible for the room to slam the rear wheel up and shorten the chainstays, making for even more power-transferring efficiency and the nimbleness described above. The externally routed cables make for easy maintenance, which we like, and also lower the bar for entry by reducing the manufacturing cost, which we like even more. Finally, though it comes spec'd with 29in tires, we'd be remiss not to note that the 429 Trail's tire clearance means it's compatible with 27.5+ tires, too.

Make biking fun again!

  • Familiarity: I've used it several times

I long for simpler days. I started mountain biking in the golden years, the mid 90's. I love to go out a shred basically anything out there. XC race, trail, resorts, it didn't matter, and I only had one bike.

The Mach 429 Trail X01, my personal bike, brings that same feeling back. Light and efficient enough for single track and the occasional mid-week race or marathon but capable enough for full on trail duty. Boost hubs stiffen up the wheelset remarkably and there's enough travel for decent drops and fast descents.

Make biking fun again!

Awesome bike, any idea the max width tires that will fit with the 27.5+ setup? Also, will this thing ever go on sale?

A dream come true

    Pivot hit this one out of the park!

    Being an owner of a 429 SL I was pleased that Pivot decided to do a longer travel,slacker version of an already perfect specimen. It really opens up more trail possibilities for the XC rider and it really allows you to just let go and soar downhill without having to be so careful in picking your lines. This will definitely be my next bike and once you demo it I can assure you it will be yours too.

    We do have some framesets coming in as well so if you need help in configuring or general questions dont hesitate to hit me up.

    WESB, I'm considering a Pivot 429 trail and would be interested in your take on the lightest build I could get. I'm riding an older Ellsworth Epiphany that is all XTR with 3 chainrings that's 26lbs.

    Thanks, Dan

    An ultra-capable 29er

    • Familiarity: I've used it once or twice and have initial impressions

    I had the pleasure of riding the Mach 429 Trail on some rough and rocky singletrack in Park City, UT. I've been interested in this category of short travel 29ers with semi-slack geometry because they represent an evolution of bikes that blend highly efficient climbing and pedaling with very capable technical and downhill ability. 29" wheels have an advantage over 27.5" wheels because they roll over obstacles much easier and maintain their momentum better so that you can keep your speed up and maximize your pedaling efficiency. The disadvantage with 29ers, historically speaking, has been that they are much less playful and harder to maneuver on turns, tight sections, and jumps compared to smaller wheel sizes. The wheels tend to have a bit more flex to them as well.

    The Mach 429 Trail is a solution to this problem. The BOOST axle spacing has allowed Pivot to shorten the chainstays which gives the bike a snappy, playful feel. BOOST also increases the stiffness of the wheelset because of the wider axles. The DW-link suspension has a firm platform for pedaling and also gives you a lot of confidence when smashing rock gardens/rough sections because the rear end stays planted and doesn't bottom out. The 116mm of rear travel is deceiving because it feels bottomless. I didn't use all of the travel even when riding aggressively. The 67.5 degree head angle is just slack enough to promote stable handling yet keep the steering responsive. The geometry of this bike really allows you to charge hard both uphill and down. I wouldn't hesitate at all to dive into aggressive terrain; this bike can handle it and will allow you to ride obstacles you never thought you could. And yes, the bike climbs extremely well.

    Something really cool about this bike is that you can run it as a 27.5 plus setup, so really it has the potential of being 2 bikes in 1.

    Another note about this bike: Pivot has a specific method for setting suspension sag and the rear shock has an indicator for where you should have it set. Feel free to consult me as I have worked with Pivot on setting sag and know the process. It is highly important to have sag set correctly to take full advantage of this bike.

    In short, the 429 Trail is wonderfully refreshing face in the world of 29er trail bikes. Forget what you thought you knew about 29ers, this bike rips on all types of trails thanks to Pivot's modern geometry and brilliant suspension design. From all day cross country rides to short aggressive descents, the 429 Trail will eat it up and put a smile on your face.

    Feel free to give me a call or shoot me an email, I'd be happy to answer any questions you have about this bike. 801-746-7580 ext 4801 or brprice@backcountry.com
