I'm playing around with a design that is inspired by vintage MTB drop-bar conversions and the 26" Rivendell Atlantis. I used Bikcad for this rendering and the wheels are 26" and the tires 50mm Schwalbe Big Apples. Does anything jump out as unworkable given the other measurements and if you were going to recommend a change, what would it be. This is a theoretical recreation/fitness/all-purpose bike. Lots of rides around the neighborhood, on local MUPS, maybe some hard-packed dirt, maybe some 20-30-40 mile rides. The goal is agile & sporty but stout enough for a large Clydesdale. Geometry is based on what I like in a 700c bike and some pulled directly from other 26" bikes or WAGS.
