The Giant Defy Advanced SL 0 adds a lot of weight to the disc brake argument.

Giant Defy Advanced Pro 2 review

Mar 2015 · Warren Rossiter

The finishing kit elsewhere is spot on for the money: a stiff stem and great ovalised compact drop bar from Giant’s own Contact SL range; the SL-1 disc wheels are typical Giant quality – smooth, tightly-built hubs with a mid-height disc-specific rim (no brake track) matched to supple 25mm Giant tyres that offer great grip in the wet or dry; and a full Shimano 105 11-speed drivetrain that provides snappy and speedy shifting that’s smooth and practically silent with it.. .
