I thought I was done building bike frames for this lifetime but my son came home last weekend with his new Specialized Stumpjumper comp. I really like the ride of the 700c mtb wheels especially on the loose sandy trails I'm often riding these days. I never thought the difference would be that great over 26". I can do without the suspension fork though.
After I did a quick sketch and some searching ,it looks like I could use OS road lugs without too much cutting, beating and bending. Darrell McClulloch's sloping TT lug set with a Nova BB and their chain-stays looks like it should work pretty well. I could make the 400mm axle-to-crown fork using Pacenti's beautiful MTB fork crown (is he still in business?)
Anyone here built one?
