hey guys - just assembled my fixie today for the first time and took it for a ride - its quite a trip, i'm in love with it.

however, i am fairly in the dark with chain tension and chainline adjustment.

chain tension: i read Sheldon Brown's article about adjusting tension and tried to follow his instructions, but they were a bit convoluded. could anyone give a description of how to tell if it is correct or not/how to adjust if it isn't?

chainline: the front crank is the same from the geared bike, an old sugino set. if i put the chainring on the inner side of the spider it is too far in, and on the outside it is too far out (although the outside is closer to dead on). the ideal spot would be in between the two, but i dont see how i can make that work with spacers on the spider. would spacers on the rear cog be smart? let me know.

also, the bike is pretty quiet, but i hear a clacking sound from the chain, almost sounds like chain slap on a deraileur. it's not too loud but its there, and noticable. is this normal?

thanks
