enantiodroma, do you want to switch to a different freewheel or go to a cog? I will not be in on Thursday, so if you want to make a change, please wait til Friday if you can. My boss is not as fixed/single oriented as me or Todd(He was not in when you came by) We should be able to do it as long as we have what you want in stock. The only thing I am having trouble getting right now is 17t track cogs, can't find them anywhere??
