I'm currently running a 46-17 and I see that i can add a cog on the opposite side of the hub (iro hub), although i probably won't flip it much. I was thinking of adding a 15 tooth cog on the other side rather than an 18 since the 17 gets me up the hills ok. Do most people gear down or up with their extra cog?

Where can I get some good cogs? Lockring? Tool to put the lockring on?

Also since I've been riding I am starting to get some chain slack from either chain streatch or the wheel settling into place. How much slack is tolerable? I assume I just loosen up the wheel and pull it back as far as I can while trying to keep it straight, is this correct?




How the hell do i track stand? By the time the light is green I have either inched my way out into the middle of the intersection or just barely unclipped before I fall over on the street.
