EAI Pro Keirin Tool

Aka the Euro-Asia Imports Super Track Tool or the Makino "Pro Tool Super".

The all-in-one tool used for installing & removing the lockring, cog, 15mm axle nuts and 10mm chain tensioners on track bikes. Super solid, forged construction.

Flawlessly crafted in Japan by Makino.

 

This tool will only work on cogs 16t or smaller. For larger sizes or seized cogs, use a traditional chainwhip.
