RISK RL207 Chainring Nut Wrench for Slotted Bicycle Chainring Bolts, 9mm/10mm Hex Openings, 93mm Metal Tool

The RISK RL207 Chainring Nut Wrench is a compact bicycle repair tool designed to hold slotted chainring nuts during chainring bolt installation or removal. When servicing a crankset or replacing chainrings, this wrench helps secure the slotted nut on one side while an Allen key is used from the other side to loosen or tighten the chainring bolt.

The tool features a dual-size design with 9mm and 10mm hex openings, plus a slotted retaining end for compatible slotted chainring nuts. Made from durable metal with a silver finish, it is lightweight, portable, and easy to use, making it a practical addition to any home mechanic or bike workshop tool kit.

Note: This tool is designed to hold the chainring nut in place and prevent rotation. Do not use the slotted end as the main force point for tightening or loosening, as this may damage the tool teeth or chainring nut.
