To answer the first question, I do have a fixed cog on the other side and plan to switch it over soon but I like the idea of coasting for the time being. So I dont know if I should switch the freewheel out to my cheaper one of keep the so called nicer one on it. The ACS I purchased was 20 bucks and has a loud ticking noise while coasting while the one on my bike now has almost no noise while coasting. He said it was a much nicer freewheel so I believe him. Yeah, what about re-greasing or lubing it? Possible, good idea or no?
