Runwell COG 1218L cog & lockring tool
This premium cog and lockring wrench was developed after Runwell engineers had conversations with European track racing mechanics about what they really needed at the velodrome.
One side can be used on 12-15t cogs and features replaceable plates to install and remove lockrings, and the other side can be used on 16-18t cogs.
Made of heavy gauge black trivalent chrome plated steel, this wrench is very sturdy, has an extremely solid feel and is long enough to provide substantial leverage.
Not for use on aluminum cogs.
