In the early '80s, when I was living in Madison, WI., I passed on a 3Rensho road bike because the 56 cm frame was a little small and the 58 was a little big. I bought a 57 cm Appel because Mike Appel was a local builder and I could talk to him about the geometry, tubing and size for ME. Also, I thought he made one of the finest fillet brazed frames I had ever seen.
I now ride a 58 cm 3Rensho.
