What's that one crankset called?
Ok so I was on fgg (fixed gear gallery) about a month ago and I saw this crankset that was suuuuuuuuper cool. It actually a complete drivetrain set... I don't know how to explain it. The chain was like flat on the top and it looked super smooth and it was black. I completely forget all the other stuff (I know that doesn't help much, sorry) but I do remember the guys calling something like the full track crank or something, I have no idea... if you know what I'm talking about then please tell me, and post a picture of what you think it is. Thanks!
