Far from every racer could afford full Campagnolo but would spend where they could
hubs, Campagnolo 36 hole- tubular rims, 195-220 gram tires ( anything less save for Shimano Dura-Ace and you were not taken seriously ) ancient Schwinn track hubs or airlite hubs were OK - very few out there.
headset - what one could afford
seatpost- what one could afford
saddle- plastic unicanitor or leather covered with no padding.
pedals- pista - Campagnolo if you could
I used Lyotard 65 with the ends cut off.
crank- TA or Sugino . Sugino could interchange with Campagnolo rings
I started with Sugino Road with the inside chainring tabs filed away, moved to Sugino track then Campagnolo with Sugino ring
bars and stem- road stem with
#65 bars
later I was very lucky and found a Steel Cinelli stem the right length and
#16 Cinelli steel bars
so much more secure feeling.
Binda Extra straps. No pulling out.
I hear the current guys at the velodrome with creaky bars and it just scares me.
