Overview
About this bike
GT's Grade 105 isn't just about getting from A to B; it's about the road that takes you there, and what you find along the way. The light, responsive, hydroformed aluminum frame offers plenty of get up and go—perfect for beating stoplights and town line sprint alike, while the custom butting and carbon fork smooth out less than perfect pavement and chipseal so you stay fresh regardless of where your next century takes you. Alex rims and Formula hubs pair well with Continental tires for a mileage-eating wheelset, and TRP's HyRd mechanical/hydraulic disc brakes provide smooth, dependable stopping power. Shimano's workman-like 105 drivetrain features lightning-fast shifts, a light, smooth feel, and 22 wide-ranging gears. The GT components and saddle are an excellent accompaniment to the Grade 105, so hop aboard and see what lies around the bend!
