Chainring nut wrench
• Material: Premium Flex carbon steel
• Chrome finish compliant with ISO 1456:2009
• The size of the hexagonal opening of the wrench is SW10. It allows you to loosen and tighten bolts of this size and can also be used to hang the wrench.
• How to use the tool:
• The wrench is used to loosen and tighten chainring nuts. Tightening starts with the wider section and, when the nut is sufficiently tight, finishes with the narrower section, which is bent to allow better power transfer during the final tightening of the nut. When loosening the nut, the wrench is used in the reverse order.
