Miche lockring
$ 12.00
It's a common misconception that you can't use traditional ISO cogs (EAI, Dura Ace and everything else) on Miche track hubs. It's not true, regardless of what some goof said on Reddit. All cog threading is the same.
You do, however, need an Italian-threaded lockring.
Just in case you missed what we said above because it wasn't written in bright red letters, this lockring will only work on a hub having Italian lockring threads (ie: Miche, Campagnolo, Phil Wood, Mack).
• 1.32" x 24tpi left-hand Italian threads
• polished stainless steel
