Publicado Por En julio 29, 2026 This was taken from a 2020 Giant Defy Advanced 1. This is Giant's own system for using hydraulic brakes with cable-pull group sets. It mounts as part of the stem and will work with many stems but I am including the stem it came with (standard 31.8mm clamp size for handlebars) . Came off an XL bike with plenty of hydraulic line to spare so included lines should be long enough for most uses. These shifters can also just be used with regular rim brakes if you want. Definitely an interesting and unique way to get the feel and performance of hydraulic brakes without the extra cost. Good condition, rear dérailler has small gash in rear of gage that cannot be seen while installed and does not effect performance.
