This premier cog and lockring wrench was developed after the Runwell engineers had conversations with European track racing mechanics about what they needed on the boardside.

One side can swap 12-15t cogs as well as loosen and tighten lockrings and the other can swap 16-18t cogs.

Made of black trivalent chrome plated steel, this wrench is hearty and has an extremely solid feel.
