Overview
About this bike
Never before has a high-tech road bike been so capable on low-tech roads. The GT Grade Alloy Expert is ready for everything, from freshly-paved switchbacks to gravel roads and everything in between. Combining a lightweight aluminum frame with a vibration-hushing carbon fork and WTB Exposure tires deliver a great ride that smooths out rough roads, yet provides immediate response when you jam on the pedals. Shimano 105 runs the gearing department, offering a 2x11 speed setup with a wide enough range to handle serious gradients. For extra confidence, TRP's HY-RD disc brakes combine the power of hydraulic brakes with the ease of installation and maintenance of mechanical brakes giving you the best of both worlds and tremendous stopping power. Point it wherever you wish to go. The Grade knows no bounds.
