About Ko Zieleman,
His father (also Ko Zieleman) started building frames in Amsterdam in I'd say the late 30's
early 1940s. Not sure when Ko (junior) started building.
Ko has a small shop in Amsterdam (currently being run by his son in law) and built mostly
custom frames. He is reported to have built bikes for Hennie Kupier and other Dutch champions
which were rebranded to whatever bike the pro was riding.
Zieleman was never a widely known dutch brand like RIH, he imported 235 bikes to the US in the 70's and
early 80's, most going through McLean Bicycles in McLean Va.
He was a very opinionated builder, didn't think much of lightweight bikes (thought they would
just break sooner, remember these were built to ride dobbles), or untried geometries.
Ko was known to mix tubes (columbus and reynolds) based on the needs of the rider,
it's not uncommon to find columbus fork blades on a reynolds frame.
Ko Retired as a builder in the mid to late 80's.
Very nice find, I recently imported a Type Special (mid 70's) road frame which I've
yet to build up.
Sono pił lento di quel che sembra.
Odio la gente, tutti.
