Reviews

Improved design

"I had a pair of the very first Ultegra flat mount calipers on my bike for the last 10 years, but bleeding them was a finicky affair that I began to loath doing. These newer models have independent bleed port and bleed valve bolts that make it so much easier to let oil out of the caliper without having to try and rotate the hollow bolt that has a draining tube/syringe attached to it. Came with all the official shimano packing, new caliper bolts and pad spacers, and 160mm adapter for the front too!"
