Dura Ace track cog chainline question / right cog for Phil hub

To be honest what concerns me more about EAI cogs isn't the 0.5mm, but the 'warning' on the PW website. I know how many people are still using EAI on phils without any problems for years, but why the hell do PW then advise against them so clearly??

I had never seen the warning. My lockring does hang outboard a bit. I also stripped the lockring threads. Expensive! I just thought it was my piss poor mechanical skills. Which it was to be fair.

I suppose there is a case to be made for DA as they are very good and half the price of EAI. The 16t problem persists though.

Unless you are building a bike to ride on the track.
