I have a mk1 Swift and a mk1 Stooge. They are quite different and I love them both. The Swift is swift and the Stooge is ridiculously capable for a rigid bike. The only sensible thing to do is keep the Swift and get a Stooge to complement it. You won’t regret it, I promise. :D
I’ve just put a Krampus fork and a 3.0 Knard on the front of the Swift as an experiment. I’m loving it.
