Cog and Lockring Wrench
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.
It’s a solid tool, grips well, hefty good feel in hand; gets a stuck cog off without any flex. I’m waiting for the lock ring attachment to really make this the only fixie wrench you’ll ever need. Stellar!
