Surly Karate Monkey chainring/frame spacing
I have a Surly Karate Monkey running a 42 tooth single speed crank. The bike was set up by my LBS (Boulevard Bikes in Chicago--great shop). There is just about zero space between the chain ring and the frame. I could fit a credit card in there but not much else. Is this something to be concerned about? I'm afraid that one little nudge and the teeth will be smacking into the frame. I know many others have run single speed Karate Monkeys w/a 42 tooth rings, so I'm wondering what's wrong with my setup---is there something I can do to adjust the crank/chain ring to move it out w/out screwing up the chain line? Isn't the frame designed to handle larger chain rings? Would going larger exacerbate this problem?
Thanks in advance for any insight or advice.
