fixedpip,

yah there is some great stuff in Amsterdam.
As you mentioned there is RIH. The original Bustraan brothers are long
gone however Mr Van der Kaay is running the shop and still building
both road an track frames.
There is Zieleman (I don't know the address) a small builder
who retired in the late 80's but who's son in law runs the shop.
Nice road and track frames, very unusual here.
Other marques you might want to look into are
de Reus, Jan Jannsen (not sure who builds his frames).
There are a few BF members from the Netherlands,
Batavus is one as is s70rguy (but he is out of town for a while).

I own an RIH and de Reus and desperately want a Zieleman.

Marty
