Amazon カスタマー 4 I bought this set to try on a flat handle gravel bike with hydraulic disks that I was initially considering converting to drop bars and GRX shifters. I had a spare set of 105 shifters lying around though and so instead of paying over ¥30000 for GRX I decided to see how cable disks with 105 would work. All I would need to do would be to remove the handlebars together with levers, brake line and calipers in one fell swoop.In the end I was very happy with the conversion. The braking performance is not as good as hydraulic of course but the caliper is easy to setup and I have no disk rub at all. When adjusting, wedge a thin card in between the rotor and the brake pad itself. Have the caliper loose on the fork mount and pull the brake lever to center the caliper. While pulling the brake lever, tighten the mounting bolts. Remove the card wedged between the pad and the rotor. No disk rub!
