Damn. I knew that screwing with the pawls is just going to cause headaches. Though the Surly fixxer hub converter does sound like a good solution for going from cassette to fixed. Yeah, I agree though it's expensive and if I don't have to spend that much, then I won't.

One of my probs on a nice project I'm working on is getting the chainline matched up precisely from front chainring to rear cog. The problem is my unusual setup. I have a MTB with road cranks (actually cyclocross cranks) and 135mm rear spacing. The road crank has a chainline that is a little less than a normal MTB crank. One way, I can deal with this is to convert a cassette wheel into a fixed wheel using that Surly fixer converter you guys alerted me to. Then, of course, play around with adding/subtracting spacers until I get the chainline in the rear to match the cranks chainline. What do you think? Is there a cheaper way for me to do this?
