Pivot Mach 429SL Carbon 29 Pro X01 Eagle Complete Mountain Bike - 2018 $6,699.00
Rocket up ridgelines and into the backcountry.
We find that in the modern world of long-and-low geometry, XC bikes sometimes end up with a bit of a bad rap, and while we won't deny that the longer-travel trail bikes have been upping their game for pedal-ability, we find it's still hard to beat the eagerness and quick handling of a true XC speed demon like the 2018 Pivot Mach 429SL Carbon 29 Pro X01 Eagle Complete Mountain Bike. Don't let its race-ready XC geometry fool you, though, the Mach 429SL is capable and ready to tackle quick rolling singletrack to big backwoods adventures with its supple suspension and eager handling. It pushes the limits of what we define as an XC bike by offering 100mm of linear travel that ramps to soak up the small square bumps without squat, and cushion you through the roots and rocks.
To achieve this singletrack-to-backcountry versatility, the 429SL uses new-school racing geometry paired with supple and responsive DW-link suspension. Throwing these two features together results in a ride that has incredibly quick, nimble handing, with plush travel to soak up the rocks and roots along the way. In order to create this quick-handling platform, the 429SL uses a steep 70.3-degree head tube angle that keeps you forward for fast maneuvering in your attack position, paired with an equally-steep 72.9-degree seat tube angle that holds you centered in the cockpit for maximum power output. The bike uses a short top tube, and is paired with a longer XC-friendly stem length to keep your bike responding fast to every movement you make. This short and forward stance not only keeps you in a great XC-race position, but also lends to long-ride comfort for endurance racing or deep adventures into the backcountry.
The latest iteration of DW-link is paired with a Fox Float DPS Kashima coated shock that's been fine-tuned specifically for the 429SL. Its tune works to soak up square edge bumps without bobbing and squat, allowing maximum pedaling efficiency when you have long, punchy, and technical climbs. The way the travel works keeps your tires locked to the ground for constant traction enabling instant acceleration and fast power transfer. The Fox Float DPS shock offers settings that are designed to offer you a plush feel when heading downhill, with control over damping and firm handling when you need to punch up fast climbs. We aren't here to convince you that the 429SL's 100-millimeters of suspension will soak up every boulder you encounter, nor will we tell you it rides like a long-travel bike when its pointed downhill, but we will say this short-travel 29'er has a sense of adventure that goes beyond logic. It cushions blow bigger than we'd expect, which we'd attribute to a combination of its wider 12 x 142mm rear Boost spacing, DW-link's linear suspension that ramps through travel, and the tendency 29ers have to roll over rocks with little resistance.
The Mach 429 SL is made from Pivot's hollow-core carbon fiber, which is engineered with a layup designed for maximum structural strength, with minimal material use to create a lightweight bike that's stronger without excess weight. Backed with Pivot's new 10-year warranty, we think you can delve into the bike with confidence that it is tough enough to stand up to the hardest riding you throw at it.
The Mach 429 SL Carbon 29 Pro X02 Eagle comes built up with the perfect array of parts that are performance minded, but still a little pocket conscious. It uses a Fox 34 Factory Kashima-coated fork that offers 120mm of buttery travel to match the rear shock, and when pairs with the Fox Float DPS in back you'll find it soaks up blows and smooths out any ride. And then there's the groupset, SRAM's Eagle X01 drivetrain offers you a massive gear range of 12 gears ranging from 10-to-50-teeth chainrings that has the power for moshing down the mountain at high speeds, or giving yourself an easy bail out when power moves and steep climbs leave you feeling breathless.
