Sitting here looking at the pictures on top of each other makes it sort of a no brainer.....I need the top bike....but want the bottom bike. SOon as the wife can get me logged into our other account so I can transfer the $$ I will be ordering the top frame. What I really would like to build would be a bike similar to the Yellow one...but with a 300 series tire and right side drive. The right side frames are a bit pricey...I have not really looked at the right side frame in the Kraft Tech catalog. Hmmm.....perhaps I should take a look before pulling the trigger....
