A bit of history, Ko Zieleman the elder started building frames in 1928, it is unclear
if he had his own shop or who he built frames for.
Ko Zieleman the younger was born in 1933, he had a successful amateur racing
career and rode professionally for the Legnano team in 1959 and as an independent
in 1960. Ko Zieleman started his framebuilding business in 1951 in a
couple of small workshops in the Reggestraat and Ijsselstraat (River
quarter). One would have to guess that this was the father who started
the business but again this is unclear at the moment.Early examples of Zieleman frames show few if any braze ons, a KZ in
the seatstay cap and a plain fork crown (no engraving). Most of the early
examples I've seen have full wrap around seatstays.
later examples with the KZ in the seatstays have brazed over the BB
cable guides and shifter bosses.
I estimate that in the late 70's early 80's the KZ on the seatstay cap was
replaced by 'Zieleman' and either a 'Z' or 'Zieleman' on the
fork crown, Ko used both flat and semi-sloping fork crowns.
I'm not sure that the KZ vs Zieleman on the seatstay caps can be used to
differentiate between the father and the son's frames.
Ko, while not well know outside of Amsterdam supplied bikes to the likes
of Hennie Kupier (Peugeot), Leo van Liet (Ti Raleigh). According to Ko
he also built track bikes for Batavus...(QUOTE by Marty) -

I just read that KZ passed away in April. Although I never met him, I owned and raced on of his bikes back in 1973-74. It was fantastic! I was riding as a junior then, mainly on the East coast criterium circuit. After I started university, I ran out of time and money, so sold it in 1979. Shame on me. Here's a few pics in better days.

That's a great story and superb looking Zieleman you had, pure class. Great pics too! Don't hear about Zieleman bikes abroad that often, especially being raced as well. Sad indeed that Ko passed away recently, let's hope his grandson can win today's giro stage and pay tribute.
Edit: Is your mate in the raleigh jersey riding a ferrari red Zieleman as well?

I think crit bikes were sort of Ko's specialty. I got this 1979 gem a while ago, built with extra thick seatstays and super tight geo. Cornering feels extremely responsive. It's so much stiffer than my other 70s and 80s bikes, comparable almost to an MX leader. Maybe partly due to it being slightly smaller, but I have the feeling Ko built it specifically for crits.
Someone sprayed it like a Concorde, probably due to a sponsor obligation, which wasn't rare for Zielemans, as Ko didn't sponsor a single soul.
