The Ultegra 10-speed cassette offers numerous gear ratio options. The shifting characteristics are enhanced by larger shifting tolerances. The redesigned sprockets lead to improved and smoother chain performance. The aluminum spider for the largest three cogs reduces weight and increases stiffness.
