Goldtec track hubs!

Sorry to bring this up, but after a bit of Googling about EAI cogs and Goldtec hubs I finally found some info in this thread.

Took them to the bike shop and they say they don't fit together. What's the best advice? Grease them up and go slowly? Use a chain whip? Never done this before and don't want to damage the threads.

Cheers.

You could try reaming the threads on the EAI.

I recently got a used DA cog that fitted on everything bar my Miche hub and every cog bar the DA fit on the Miche hub. Quick spin through with the BB thread reamer (threads are the same size, don't use the left hand threaded tap!) and the DA now fits the Miche. I had to use a chain whip to hold the cog btw.

Rotafixing is for people with no (decent) chainwhip and/or no guns. I can skid my trackbike which has no lockring and a cog fitted using just a Park SR18.
