So I don't know much about bikes at all, had the bike at the shop and they were unsure of the noise. It's coming from the front, clanging/tapping that will come and go. From reading online I'm guessing it has to do with the ACCT, I understand the concept of such but am unaware of where it's located to be able to do the so called "trick" to see if it has gotten stuck or what. Does anyone have a pic or something of it's location so I know what I'm looking at? Thanks!
