The Rotor is basic Canyon road spec when they ran out of Tiagra or 105, surprised I don't see more of them around. NW direct mount ring cost me about £40 and turns them into a nice light (ish) fixed crankset with 24mm sealed BB. 43.5 not 42 chainline but 3/32 so hardly an issue with a track chain.
Crankset envy !
