Overview
About this bike
Work or play, tarmac or gravel. Why not “All of the above”? GT's Grade Tiagra is all about breaking down barriers so you can ride wherever your heart desires. The light, responsive, hydroformed aluminum frame offers plenty of get up and go—perfect for beating stoplights and town line sprints alike, while the custom butting and carbon fork smooth out less than perfect pavement and chipseal so you stay fresh throughout your next Gran Fondo. Alex rims and Formula hubs pair well with Continental tires for a mileage-eating wheelset, and TRP's Spyre mechanical disc brakes provide smooth, dependable stopping power. With a Shimano Tiagra drivetrain, you know each shift will be crisp and easy. The GT components and saddle are an excellent accompaniment to the Grade Tiagra, so hop on and see what lies down the road!
