bicycle sidewall stability-Shimano R8000 Ultegra Cassette 11 Speed

Replace your old worn out cassette with the Shimano Ultegra 11 Speed Cassette. Shimano's Ultegra cassette uses Hyperglide sprockets with revised tooth profiles for reduced wear and lightning quick shifts. A rigid aluminum carrier keeps the cogs in check for improved shifting under the most demanding gear changes. The available ratio combinations work extremely well with standard, compact or triple cranksets.
