Hi,

I'm new to biking and really new to fixed gear cycling. I bought a cheap aluminum fixed gear on ebay and I really enjoy riding around with the fixed gear, its pretty different than any other bike i've ever ridden. My question is, this bike has a flip flop hub with a fixed gear on one side and a free wheel on the other. With the hub using the free wheel gear the chain runs in a straight line from the crank to the wheel, but when I use the fixed gear the chain runs at an angle to the crank. Like there should be a spacer in between the wheel and the gear. When I am riding I can feel tension when i'm pedaling, like the chain is binding a bit. Is this normal or is there a way to fix this? I could have the chain too tight but i've experimented with different tensions and and any looser and there is slack when I'm pedaling. Any help would be appreciated.

Thanks.
