Trying to fill in the gaps here with what i found on line and the disappointing LBS experiences.
Looking for options to convert this frame to single speed. Just looking for a decent crank/BB combo that will work on the 73mm shell. Bike shops guys seem disinterested at best and one just handed me a catalog and told me to pick what I wanted and he would order it. I could do that from home.

Any starting points? Preferably mid ranged stuff as this is my first bike and looking at it as more of a learning experience to grow on.

Thanks in advance.
