A tool to tighten up loose axles on tall unicycles.
A indispensible tool for tall unicycles. The bottom bracket (where the pedal axle is located) is subject to a great deal of force when the unicycle is ridden backwards and forwards, so its not surprising that the lockring will work loose occasionally.
This tool is a double sided bottom bracket lockring hook spanner (also known as a C-spanner). One side is a single hook, the other is a hook spanner with 3 notches for better engagement in the lockrings. The three-hook end will fit 3-notch lockrings with a maximum outside diameter of 46mm, and minor diameter (in the notches) of 40mm. Weight: 210g.
