Noodly no more.

The Pivot Mach 429 Trail XT Pro Complete Mountain Bike combines the aggressive angle of attack that made 29ers the kings of XC with stiffness-enhancing Boost hubs that eliminate the noodliness and unwieldy chainstays we used to accept as the trade-off. Shimano's XT kit recently got a similarly impressive update, inheriting much of the tech of its more expensive stablemate, XTR, but retaining the trail-proof reliability and self-sponsored pricing that has made it so well loved.

Of course, no amount of innovation and drivetrain shininess can make up for a poorly built frame, which is why Pivot developed its 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 has 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.

The 429 Trail's DW-Link suspension takes a handful of queues from Pivot's Mach 6 and Phoenix frames, teasing a depth out of the 116mm of 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 — especially when paired with the responsiveness and decreased deflection of the wider, Boost hub standard.

The Boost 148 rear and 110 front axle standards allow for more width across the board: hubs, chainstays, bottom bracket, and chassis. This makes for a shallower spoke angle, which considerably stiffens the 429 Trail's wagon wheels. It also accommodates wider pivot placement for longer life in the suspension bearings and a stiffer rear triangle. That extra width leaves room to slam the rear wheel up, too, shortening the chainstays for even more efficiency and dexterity, and it also makes the 429 Trail compatible with 27.5+ tires. 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.

picture clarification

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

I just wanted to note that the seatpost that comes on this build is the Phoenix carbon as stated in the specs. The picture shows a different post and that is incorrect. If you have any questions on this build or want a dropper on it please feel free to contact me here kylebrown@backcountry.com

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.

Hit me up directly if you would like to know more. 801-204-4557 btowery@backcountry.com

I was wondering if 3.0 tires such as the Vittoria Bombolini would work on this rig?

William, the 429 Trail will accommodate 27.5+ set ups but not 29+. Give me a shout and we can go over more options for you. 801-204-4557 btowery@backcountry.com

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. They 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 improves 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
