XC speed meets aggressive trail charging with Giant's Anthem Advanced SX 27.5. The Advanced-grade composite frame with ALUXX SL rear triangle creates a nimble feel that's fast on the climbs and ready to charge on the descents. Courtesy of RockShox's Monarch RT DebonAir shock, 100mm of travel keeps rear wheel traction pegged, while the RockShox Revelation RL with 120mm of travel up front takes on the big hits and the chatter with equal ease. 27.5-inch Giant composite wheels are nimble enough for weaving technical lines and big enough to steamroll everything else, and they're wrapped in Schwalbe rubber for sticking the corners. A trail chameleon like this needs a drivetrain that can handle the ups, downs, and everything in between, which is why SRAM's 1x11 X01 powerhouse adorns this rig. And with all that speed, you'll need reliable brakes that can modulate, so SRAM's Guide RS discs are on the case. A Giant Contact SL Switch-R dropper post lets you get into the best descending position possible, too.
