Runwell COG1218L Fixed Steel & Ti Cog Wrench
In stock
Runwell COG1218L Fixed Steel & Ti Cog Wrench is a cog and lockring tool for installing and removing fixed gear cogs from 12T to 18T. Its main advantage is that you don’t have to struggle with a chain whip that can slip and damage the bike or you. The tool grips the cog directly and transfers torque efficiently, making it easier to remove cogs that have seized in the hub threads.
Runwell is a Japanese tool brand from Tsubame-Sanjo, specializing in hand tools for track bikes and fixed gear. COG1218L was developed at the request of a mechanic who wanted to work faster when regularly changing cogs. One side fits 12–15T cogs and the other fits 16–18T, while the tool also works as a lockring wrench.
This is a particularly good fixed gear cog tool for bicycle mechanics and velodrome cyclists who often change their gear ratio. The wear plates can be replaced, giving the tool a long service life. COG1218L is made in Japan and designed for steel or titanium cogs and lockrings—not aluminum or carbon fiber.
