Cages are same length. I’m not questioning the data in Disraeli Gears but have trouble matching it up in real life to the two derailleurs (except for the cage lengths). My Cyclone is lighter, not heavier and I’ve ridden both with 25t cogs, tested on the stand the superbe pro up to a 28t cog and it seems to wrap around 30t which I think is considerably more than spec or what either Disraeli or Berto show. I like the SP so much I don’t know if I’ll ever get to the several Dura Ace or Sante or newer Superbe Pro. I can, but don’t, run the entire 12-25 9 speed cassette on each chainring of a 46/38/28 except small small.
