I have the Iro/Formula hubs. Yesterday when i checked my rear hub the lockring was so lose i just removed it by hand. I know there was a recent thread about this already but search isn't working for me.
A) should i ditch the formula lockring and replace with Dura-ace?
B) (in case answer to A is no) the formula lockring has a flat side and the other side has a chamfer, does it matter which side is against the cog?
Thanks.
