http://www.radiks.net/~ladue/ is Denny LaDue's website. His pictures are a bit old but you get the idea. I'll have a MTB rear wheel and my frame basically has a big X in the middle, not like the ones shown. Since I'm 6'6" it's pretty long too. With no wheels, end to end it's about the length of me.

I went to get chain tonight and he asked how many gears. To start with I only have a 5-speed rear wheel, will the chain have to change if I go up to a 6 or 7 speed rear wheel?
