I am thinking about switching from my 9spd. Chorus 13-26 cassette to a 9 spd. Chorus 13-23 cassette. Will I need to make any adjustments to my rear derailleur or will I be fine as is? I want to be able to switch between my Rolf Aspins ( I am planning on mounting the 13-23 cluster on this wheel) and my training wheel, which happens to be a Vento, which has a 13-26 rear cluster. Keep in mind that I am riding on a Campy Chorus medium cage derailleur, 10 speed.
TIA,
Runce
