I just installed my Sugino 75s, complete with the "official" Sugino 75 square taper BB and an Alter chainring.

There's obvious side-to-side wobble as I spin the crank. I was expecting something a little more "pro" with this setup. I don't have the bike with me ATM, but I'm gonna try re-installing the cranks on a different spindle location and checking the chainring.

Anybody ever experience this? Any ideas?
