It was originally designed for a suspension fork, but judging from the original geometry and the riding geometry (rode it around with just the back brake for 10ish miles) on the saggy fork, riding one with a rigid fork would be suitable. I was primarily curious as to how one would go about setting up a bike with a new fork, given a certain head tube length. What ratio would one need for a replacement fork as far as steer tube length vs. head tube length?
