Shimano Ultegra R8000 11 Speed Mechanical Groupset w/Hydraulic Disc Brake System

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.

Ultegra 6700 Mini Groupset With Shifters And Front And Rear Derailleurs

Got this off a bike I bought. Kinda been ridden hard but works as intended. Lots of cosmetic blemishes and the left shifter makes a clink noise when you shift but I think the mechanism just needs a clean and relube. Anyways feel free to ask any questions! I put brand new hoods on it.
