howdy ladies and gents
just stumbled upon this place when i shold have been working, and it seems like the right place for me to ask a question i have.

i just entered the world of fixed-gear riding. i was a mtn rider at first, and when i moved i got a fixed gear to commute on, because i had heard that they were great for fitness and cadence. anyway, i love my bike and i commute on it everyday, but since i have no real experience with it i dont know what i need to look for maintenance-wise. it seems like it should be pretty simple, keep the drivetrain in line, tires pumped and chain tight. i just want to make sure im not missing anything. also, how often do you guys replace your chains? ive been riding since june, probably about 8-10 miles a day. should i be worried about stretch in the chain yet?

thanks for you help
peace
