I quite like the 4 arm design but appreciate not very traditional looking. The current silver 11 speed centaur groupset would have the benefit of taking up to a 34T cassette, not sure that Athena range had a medium / long rear mech option and is limited to 29T so I really donβt see the benefit over 10 speed tbh.
I think its the last gen Centaur ultratorque groupset came with a compact chainring in 110bcd and a long mech at the rear.
Campa only started making bigger cassettes recently of course but adding a shim/sram cassette could work we've all done it before π
I currently run last gen Centaur ultratorque compact chainrings with older aluminium Ergopower centaur levers on my winter set up and it works beautifully, hence I wanted another set as back up / future build.
