Giant's Talon 27.5 4 is like Goldilocks: not too big, not too small. The 27.5-inch wheels provide the acceleration and lightweight feel of a 26-inch wheel, with the traction and efficiency of a 29er. It all starts with Giant's ALUXX aluminum frame that's tough, yet light and responsive, just what you need for singletrack excursions. Then you get a SunTour fork with 100mm of suspension to float you through the rough stuff. For the shifting, a Shimano 27-speed drivetrain tackles the hills, and Tektro hydraulic disc brakes provide great speed control on the way down. And up or down, 27.5-inch Giant wheels and knobby tires grip with authority and roll over anything in your way.
