Patrick, I was running a 9sp 12-25 cassette with a Suntour Superbe Pro short cage and a 46/38/28 with down tube shifters and the derailleur is well named. To my amazement I could run the entire cassette on each chainring with only the slightest sag small/small though in practice I don’t do that. This appears to be way outside spec.
I then swapped wheels and crank and am now running a 14-28 7 sp freewheel with a 50/45/26 crank. It does not like the 26/28 combo and doesn’t wrap enough chain in general on the 26t ring but is rideable. I will probably swap out the 26 for a 28 or a 30. I am super pleased with the Superbe. Though I haven’t ridden it with 10sp or barcons I have no reason to believe it wouldn’t be wonderful with both. Since mounting it only recently I read on Disraeli Gears that some consider this derailleur to be the best shifting friction derailleur of all time. I don’t have nearly enough experience to make such a claim myself but can well imagine it might be true.
