Given same brand (eg Campy) and level (eg Chorus) of components, does a medium cage rear derailleur (rd) shift as smoothly as a short cage rd?
Any other downsides to switching to med cage?
Am asking b/c am looking for lower gears for climbing (Cat 1 coming up). Curr have 50/34 chainrings and 12-25. Looking at 13-29 which requires med cage rd.
Have campagnolo components.
This would be for Tarmac listed below.
