I don't know if its been said tldr. Eff sram! Axis is nice, but it is far too expensive. Mostly owing to the proprietary garbage that sramm instituted with this groupset.
I was a staunch sram guy. But my next bike will be shimano.
I bought brand new 11 speed e tap group just last year. Now discontinued to divert sales to the new axs group. Now its not supported by the parent co. No parts, no spares nothing. If it fails I'm screwed. Well thank you very much Sham.
I have a Force axs groupset on a '16 tarmac. Functionally its fine, but its heavy. Red would have cost me another $1800.00. I have built entire bikes for that much. Just to gain a little weight savings? I couldnt do it.
The proverbial straw was the proprietary shenanigans with its parts not being backward compatible. And inventing another entirely new bb standard just to force you to buy the new crankset. Made me feel like had been on a date with Bill Cosby.
My advice advice Dura Ace or even Ultegra. There is really nothing to gain with Sham. Except room in your wallet.
