Hey Fiat, love that bike! So cool that you're keeping the seat-tube rod-actuated front derailler and half-step front rings. +1 on the Panaracer gumwalls - I love them on my Miyata. You know, they make aluminium Ashtabula cranks now (for the BMX market). When you have to rebuild the bottom bracket (which requires no special tools on this bike) it would be an easy upgrade. So nice to see such a beautiful example from a time when Schwinn was keeping the flame for adult cycling.
