In creating the 2016 Mach 429 Trail X1 Complete Mountain Bike, Pivot took a bit of a mad scientist approach, piecing together a bike that tackles big hits with lithe, nimble style. With inspiration from the sprightly cross-country 429SL, enduro beast Mach 6, and downhill demon Phoenix paired with Fox's trail suspension kit and a dose of SRAM X1 componentry, the Mach 429 Trail manages to simultaneously haunt the worlds of XC and enduro, hitting all the marks for a quiver-killing trail bike.

The 429 Trail's DW-Link suspension owes its versatile 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 tumbles out of 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.

Incredible bike and quite a surprise

  • Familiarity: I've put it through the wringer

Having been on a Pivot 5 for 8 years and didn't think riding could be any better, I gave in to an update to a 429 Trail. I was amazed at how it handled tough uphill rocks that I just thought I was flying thru on my old bike. The rock gardens were passed with incredible ease. Pedaling with X1 and suspension is great and I haven't had a need for more gears-it just keeps getting faster. Love it! If someone had tried to convince me how great it is I would have had doubts.

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.

Trail Machine

  • Familiarity: I've used it several times

The latest Pivot trail and all-mountain bikes—the Mach 4 and Mach 6—have been a big success, but most recently the 29ers have been restricted to the cross-country end of its lineup. Now the new Mach 429 Trail lets 29er fans enjoy the excellent dw-link suspension on more rowdy trails.
Pivot started the design with a ride experience in mind, not a travel number, so while it may seem odd that the bike ended up with 116mm of travel, the new linkage design features influences from the Mach 6 and Phoenix downhill bike for a much larger feel. The suspension moves through a custom tuned Fox Float DPS shock with two sets of valves and pistons similar to what is found in the dual chamber Fox Float X shock.
The full carbon frame is designed for a 120mm or 130mm fork and while it’s sold as a 29er, the Boost spacing front and rear allow it to fit a 27.5×3.0 wheel and tire too.
If built with a single chainring, the mount is removable for a cleaner look. The external routing also makes the frame a little less expensive than the Mach 4 or Mach 6. Like all Pivot bikes, the bottom bracket shell is a Shimano PF92 that allows the frame and bottom bracket junction to be as large and stiff as possible.
The geometry is in line with the current trend with a longer front center and slacker head tube angle. At 67.5 degrees it is on par with the new breed of 29er trail.

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 also tend to have a bit more flex to them.

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.
