We are using Shimano Ultegra as this is more common than Dura-Ace, but the same differences roughly apply. We also wanted to include SRAM so poached SRAM Red Mechanical and eTap off a couple of Si’s bikes. Jon also managed to get his grubby hands on Campagnolo Super Record. Santa was very generous this year!
