• is that ultegra di2 hydro discs? if so i can tell you know, it's fucking awesome

  • Didn't go full hydro ( I know I probably should have) so am trying a hybrid system that has got some good reviews..

  • I used the hope V twin system and then changed to full shimano hydraulic (one bike mechanical the other one di2) the difference is huge between the hybrid-kludge and the full hydro
