Hi OP.
ignore the dick quoted above. I'm a 42 year old exec that's been riding bikes all my life and have a state contender. I prefer the constant effort mixed with the sheer terror of a Fixie and don't look good in Lycra so go fixed. Anyway, I love the contender but had to make a couple of changes. Get a new lock ring as the one that comes with the bike has the consistency of cream cheese and is prone to slipping. Also, swap the chain for a better one while you're down there (I went with a SRAM). Not essential but it makes a hell of a difference. The 48:16 ratio is a bit tough on anything but the flat plus an even/even ratio is difficult for skids. I'm going to swap cogs to a 48/17 ratio which will be a bit lighter and easier to stop. All up with around $50 in tweaks you've got something really special. All up the bike is quiet, responsive, bullet proof and insanely fast. Good taste buddy.
