10 Speed Capreo Cassette. Please understand, you need to have a Shimano Capreo or one of the Capreo off brand hubs specifically made for this cassette. A standard 10/11 speed hub will not accept this.
This is a direct replacement for the Greenspeed Aero Cassette and will fit 10 speed Capreo hubs on certain ICE trikes.
