While down at Cirque, I overheard someone saying that 4x with low flange spokes was a no-no, and some more of the conventional wisdom of the sages past. I and opened my eyes a bit, just looking at the flock of bikes in the stable there.
Lo! Behold! Richard Sachs's Masis both seemed to be 4x low-flange. Last weekend I bought a Medici touring bike, 4x low flange Campy (Tipo) hubs.
Now, was this something they special they smoked on the Left Coast? All I really know is that 4x uses the same length spoke HF or LF, and they wheels seem to stand up and last either way.
Curiouser, and curiouser. I wasn't ever good about the esthetics aspect of stuff. :-)
