Shimano 105 CS-5800 11 Speed Cassette

The Shimano 105 cassette is the perfect choice for the the ultimate in pure utility and value when choosing an 11 speed cassette. It is identical in every way to the Ultegra 11 speed cassette except it uses a steel carrier instead of alloy. While not quite as light as the Ultegra, the performance is the same.

Durability is the same as the excellent CS-6700 to perhaps better considering the matching CN-6800 chain can be expected to last 20% longer thanks to its PTFE coating. This coating along optimized chain width allows shifting on the CS-6800 cassette to be smoother and quieter than ever. The 6800 cassette can be used with the 9000 group as a slightly heavier but more affordable option.
