SHIMANO cassette 9 speed CY01810
In order for the bike chain of older bikes or perhaps that of children's bicycles to be compatible with the Cyclus2, it is necessary to equip the Cyclus2 brake with a 9-speed cassette. With a Cyclus2 brake unit, converting a cassette pre-mounted to a freewheel body can be done quickly and easily by the user. The freehub body must be ordered separately.
