In contrast to the CS R7100, it's compatible with both electronic and mechanical groupsets. With only about 15 grams more weight than the Ultegra model, it offers fast and smooth shifting, even when you pedal hard. It has the same width as an 11 speed cassette, so the sprockets are closer together. This
