Charge beyond the rolling singletrack.
Maybe you've had enough race days on your XC rig, and are feeling ready for adventure beyond the rolling singletrack, but you still have a soft spot for that quick-rolling 100mm speed demon. Fortunately for you, the engineers over at Pivot Cycles can relate, which is why they've thrown together the perfect combination of race-ready geometry, and a plush feel that grips loose deer tails beyond the local trail network with the 2018 Mach 429SL Carbon 27.5+ Race X01 Eagle Complete Mountain Bike. Tried and true, the 2018 Mach 429SL keeps going with the geometry we know and love, and the boosted chainstays of last year so that you can cook it into berms with the plush feel of 27.5+ wheels that previously would have been balked at by the XC community. This rig gives you the flexibility to swap back and forth on a whim between 29ers when you want to hit the trail on race day, and 27.5+ hoops that give you a little more squish, and exceptional traction for sure-footed control as you push beyond the beaten path to uncharted terrain.
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 420SL 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 ride 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 plus wheels have to gobble up the chatter 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 27.5+ Race X01 Eagle brings some pocket-consciousness to the build, without skimping on the huge gear range that Eagle has to offer. It compiles an assortment of GX Eagle and X01 Eagle components to give you snappy shifting, and a 50-tooth bailout cog that gives you relief when your climbs feel nearly vertical. It uses a Fox 34 Performance fork that offers 120mm of 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.
