For those that have Di2 & hydraulic brakes, are you using the integrated Shimano Ultegra Di2 with hydraulic levers? I think I read that you are using 180mm rotors right? Is Calfee willing to use these on their tandems even if Shimano hasn't blessed it? Has anyone with Shimano hydraulic brakes overheated them on a big descent?
Thanks again for your help & experience.
if you do not require low climbing gears then why would you consider disc brakes? Can you live with a wide ratio cassette? KISS!
