Giant's XTC Advanced 27.5 3 is an XC racer's delight that's equally interested in crushing your riding buddies after work. A born climber with the heart and soul of a fast descender, the XTC's nimble ride comes from the Advanced-grade composite frame that soaks up trail vibration while maintaining stiffness for awesome pedaling power. On the front, the RockShox Gold TK Solo Air fork mutes chatter and devours big hits with 100mm of travel. Giant's 27.5-inch wheels add quickness through techy sections and stability everywhere else. You'll get up to speed on the quick thanks to Shimano's Deore/SLX drivetrain that slides effortlessly into the right gear every time. Ever-reliable Shimano hydraulic disc brakes modulate for better control and this lightweight racer is topped off with Giant components like a tough seatpost, low-rise handlebar and a supportive saddle.
