With generous travel and the addition of plus-size clearance, RockShox's 29/27.5+ Pike RCT3 Solo Air 160 Boost Fork will immediately become the ultimate piece of all-mountain weaponry in any enduro arsenal. Since the Pike's reinforced Power Bulge bushings are already pushing the fork into nuclear-grade anti-deflection territory, pairing it with a stiffer Boost axle adds even more "cat" to its "cat-on-carpet" tracking. The option to run 27.5+ tires further increases the fork's capabilities with better traction while locked out on slick, rooty climbs and more plushness while mashing through crunchy stuff that — in hindsight — you probably should've tried to pick a more diplomatic line through.
The Solo Air fork ditches the adjustability of the Dual Position Air version in favor of a single 150mm travel position. You lose the ability to drop the front end of your bike by a couple of centimeters to make it more aggressive on the climbs, but for some, the extra weight saved (about 50 grams) and the complexity saved is worth it. The Charger damper's adjustability means it's still a comfortable climber, but the Solo Air really shines on the steepest and most technical downhills you can stomach.
Of course, the Pike wouldn't be in the pole position of the six-inch travel game if it were rigidly un-adjustable. Depending on the terrain you're climbing up or dropping in to, the fork's settings can be dialed by the three-position RCT3 switch, which lets you choose discreet amounts of lockout for bigger hits, trail terrain, or cross-country speed. With the addition of 3in tires, you also have additional play, even in the stiffer settings. RockShox's Rapid Recovery feature indulges the Pike's terrain-gobbling tendencies by keeping recovery between hits short, so you'll always have that cushion, even during multiple successive bumps.
