Shimano Ultegra 6800 11-speed cassette for Shimano 11-speed shifting systems. The Ultegra 6800 11 speed group follows the principle that there must be a proper gear ratio for every sort of rider. The different types of cassettes make it possible to ride each type of area.

In addition to the extended cassette range, there is also an eleventh cog added to the Ultegra 6800 Cassette. As a result, the cassette has a nicer progression across the range. Thanks to the HyperGlide technology shifting is smooth all sort of conditions. Despite the eleventh cog, the weight of the cassette has barely increased.

Richard, 7 February 2018

Great quality with improved climbing

Just made the change to a 11/32 ratio with this cassette which delivers the trusted quality and reliability of Ultegra 6800. The first ride on this set up delivered an improved performance in a regular tough local climb that has 20% gradient in parts. Very pleased with the results.

Pros
  • Quality
  • Reliability
  • Improved performance
