I recently purchased an early eighties European road bike. The Badging reads "Schweitzer Sarreguemines".
Group is 600EX Arabesque. Wheels are Mavic E 700c. Cinelli 1R stem and Cinelli Giro Italia bars. Blonde San Marco Concur Supercorsa saddle. Navy blue with chrome head lugs, fork and chain-stays. A gorgeous bike.
So far no one has heard of this builder. I'm suspecting it may be of Swiss origin. Anyone know for sure?
