Giant's TCR Advanced SL 1 is a true speed machine, specially crafted for railing corners, climbing mountains, and edging out sprints. From the massively oversize PowerCore bottom bracket to the MegaDrive down tube, full composite fork, and sleek, integrated seatpost, every inch of the sub-2-pound TCR Advanced SL frame has been optimized for ride quality and speed without compromise. The full composite fork is just as focused with its massive OverDrive 2 steerer and feathery weight. Hanging off this gorgeous composite chassis is the top-shelf Shimano Dura-Ace 11-speed group that delivers near-telepathic shifting and braking. And, Giant's featherweight P-SLR1 wheels, composite bar, and composite stem will help climbs disappear beneath you as you leave your competition behind.
