Tracks Sprockets why are tracked vehicles usually have the drive sprocket in the front?
its less moving parts to stretch to the rear of the vehicle. you don't have to have a separate drive shaft and rearend to run the vehicle. since you don't have a spinning driveshaft to break on rocks and other off road problems, you don't have to worry about what is scraping the bottom of the vehicle

do i need special cranks for my fixed gear bike?
i recently put a fixed wheel on an old 10 speed, and i have enjoyed it, but i think the reverse turning pressure on the cranks has semi-stripped one of the connections where the crank meets the bottom bracket. now it slips all the time. i know there is tremendous force there when i resist the pedals to slow down. am i supposed to have some special one-piece track crank/sprocket thingamajig? my old 10 speed setup is about to give up.
It is probably least expensive to just replace the cranks and bottom bracket with newer ones than to try to fix what you have. I think Sugino makes a crankset primarily for fixed gear bikes. I use a brake and have never had any problems with my drivetrain and also feel much safer that way. If you do insist on slowing by resisting and stopping by skidding, make sure you are running a track hub with a reverse threaded lockring, not a converted road hub.
