I'm completely new to this but I'm committed to a 69er or at least a 26/650B conversion. I'm looking at building a simple rigid bike with good geometry. Is there a frame recommendation page? So far I've been looking at bikes with more than 100mm travel on front forks. The couple I'm considereing are Mongoose Amasa Comp Elite and Cannondale F7. Are either of them suitable?
My next next quest would likely be to find a fork that's about an inch and a half shorter, protrudes more and still takes a 29" wheel, but that's for another day.
