Are there any 30mm spindle crank arms that could be mated to Ultegra 12 speed chainrings?

If we’re counting DUB as “30mm” then get a Croder spider + SRAM DUB crankarms.

This is definitely on the top end of the price scale, but what about Cane Creek's Ti cranks?

Easton with a Sigeyi or Xcadey PM is another option

Rotor spider 's shape have certain small detail that cause Shimano ring to not fit without a bit of modification (filing).

Maybe a silly question but...why are you limiting options to 30mm?

Oh that's annoying. Thinking back I must have only fitted Rotor rings on Shimano cranks and misremembered doing it the other way. Thanks for the detail :thumbup:

For 8-bolt, the Croder equivalent is definitively better in terms of finish and tolerances...it's also a couple grams lighter.
