It’s a good article, though he does stress that it’s a very personal build, squarely aimed at NS riding, similar to PVD’s Spitfire.
If I had the cash, I’d plump more for the Waltworks, but also, at the other extreme, I’d like to try something like a 29er that was taller and shorter than the current norm. I’ve had it in my head for a while, similar to Pompino geometry, taller headtube, good clearance and upright position for coastal exploring.
