Cog Wrench


Sold Out

This premier cog wrench was developed after the Runwell engineers had conversations with European track racing mechanics about what they needed out of such a tool. 

They learned that many European track riders don't use lockrings and therefore, cogs can be swapped extremely quickly between races to maximize their riders' performance for each track. 

One side can swap 12-15t cogs and the other can swap 16-18t cogs.

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

Weight: 355g
