Shimano HG61 9-Speed Cassettes.
- 12-36t 29'er-specific cassettes must be used with either M529 (6-bolt) or M629 (centerlock) hubs, which are designed and manufactured specifically to withstand the extra torque load exerted by the 36t low gear
- Use of the 12-36t cassettes with other hubs may result in hub-failure and may void warranty coverage
