Bonjour,

Test of pulleys of rear derailleur Campagnolo!

I have an old pulleys Campagnolo Record of the years 1990 fact for 8
speeds, with ball bearings!

Definitely broader than the 9/10s current ones (approximately 9,70 mm).
I want to test it on a derailleur Campagnolo Chorus 9 v 2001!

What you of the results think on the risk, the quality of the change of
speed, in spite of the width and the absence of side play ?


Not noticable and you will nned to modify the back plate of the rear
der to accomodate the larger pulley bolts. Not worth it, IMO. Standard
puleys from Campag work well, spin smoothly(use grease), and last a
long time.
