From this info, "Criterium" is clearly the right name for the chainrings. But they state that the rings are 153, not 151. I just measured mine, and can't argue with 153, but 2mm isn't much and I might easily have believed 151 as well if that had been my expectation. Honestly, if I had had no expectation at all, I'd probably call it 152. Regardless of the BCD, these rings won't work with Campy old Record, as Record was 5-arm, and the TA Criterium rings are 6-bolt.
