Shimano’s Ultegra-level cassettes are one of the crucial gems of cycling components. Significantly inexpensive than the highest-line Dura-Ace offerings, they are also more durable, and only fairly heavier. And, they are heavier within the center of a wheel, where their effect is negligible. Shimano’s improved its shifting ramps in this iteration, too, that means the fabulous shift quality you are expecting from the Japanese component giant is even better than you understand that.
