Per tool: chain retainer for 10 or 11 sprockets plus puller
The counter-holder is suitable for holding cassettes on 10- or 11-speed sprockets. The puller fits all Shimano and SRAM cassettes. These all have the same toothing in the mounting ring for the cassettes. This means that Shimano pullers also fit all standard cassettes. The Centerlock brake disc mounting also has the same toothing, so the pullers fit here too
