I think the drive side pivot bolt by the derailleur is creaking.

I think a full overhaul is due but I am not sure where I should take it.

Perhaps I should rephrase, is there any local bike shops ya'll can recommend that has experience in overhauling Nicolais ?

I wish I can work on my bike..however I am pretty sure it will explode on the first ride if I were to service it.

Thank you in advance for any recommendations!
