Giant's Defy Advanced SL 1 combines ultra-light performance and compliance for epic days and every day. This svelte, race-ready rig boasts a tuned composite layup, tall head tube, and relaxed geometry that offer new levels of comfort and control. Giant's full composite OverDrive 2 tapered fork nullifies road buzz and guides you with authority. The wheelset does, too, with Giant's composite P-SLR0 hoops and P-SLR1 tires loving the corners and keeping your rolling resistance low. Plus, Shimano's legendary Ultegra 11-speed drivetrain provides pro-level shifting and their hydraulic-disc brakes deliver incredible stopping. Of course, the Giant finishing kit perfectly matches a bike of this caliber.
