Cassette Shimano Ultegra CS-HG800 11-speed 11-34

The CS-HG800 cassette is based on Ultegra level. With a gear ratio of 11-34 teeth, it is suitable for racing bikes in mountainous terrain as well as for mountain bikes. The gear changes are extremely precise, so that the switching breaks are very short. An intelligent material mix of aluminum, carbon and steel increases the life, but at the same time reduces the weight of the cassette. So the biggest 4 sprockets are connected with an aluminum spider and the following 2 sprockets with a carbon spider.
