Currently working on this aluminium Zieleman. I got the bike with a mixed groupset including 126 mm record hubs, Modolo Orion downtube shifters, and first generation chorus monoplanar brakes.
Does anyone have an idea how old the frame is? I'm guessing late 80s.
I have found on this forum that Zielman sold aluminium bikes. Were did he buy the frames?
Thanks for your help!
