The Classified Cassette is a unique cassette system designed to offer a wider gear range than traditional cassettes while also reducing weight and improving shifting performance. The cassette uses a 2-piece design with an outer ring that attaches to the hub and an inner cassette that slides onto the outer ring.
The Classified Cassette is available in two versions: 11-speed and 12-speed. The 11-speed cassette has a 11-32 tooth range, while the 12-speed cassette has a 11-34 tooth range. The cassette uses 8 cogs that are made from high-strength steel and 3 cogs that are made from lightweight aluminum. This combination of materials helps to reduce weight while maintaining durability and reliability.
One of the unique features of the Classified Cassette is its ability to be shifted while under load. This is made possible by a patented shifting mechanism that allows the cassette to shift up or down by up to 3 gears in a single motion. This allows for smoother and faster shifting, particularly when riding on steep climbs or during sprints.
The Classified Cassette is compatible with Shimano and SRAM 11-speed and 12-speed drivetrains, as well as some Campagnolo 11-speed drivetrains with a specific freehub body. It is also compatible with most standard hub designs, making it easy to install on most bikes.
