Hmm, never even seen these.

Does that mean I could use my 155mm Rotor cranks with 30/46 GRX rings?

stelfox in reply to @hippy

depends how old the cranks are, are they the newer attachment (aldhu, vegast) with finer teeth or the older wavy one like on 3d+?

Ah, yesh, these will be the bigger splines as they're the 3D+ version. GLWS.
