My main commuter is a left hand drive fixed gear single speed.

I use SPD pedals, which have poles. So, to make the crankset work, I installed helicoils in the cranks so that I can have my pedals oriented correctly. Rides exactly the same really. The rear hub is set up with a Shimano Deore XT, HB-M756 hub (6 bolt disc front hub), that has the original axle replaced. The fixed cog is bolted to the hub where a disc rotor would go.

Fun bike and to be honest, most people don't even notice that my bike is not "normal".
