Used for 1 month only. Were new when I fitted them,. coming from my Canyon Grail. I have the cover for the gear groove, the mounting point on the front of the bars to which you can attach a multitude of different accessories including TT bars. There is also a flat shelf on inside of the drops which I think is for SRAM wireless blip integration as it mimics the flat area on Zipp XPLR carbon bars designed for that purpose. The only slight marks are from where the shifters were clamped.
