BITD, like the 70's, the discussion of the difference was frequently stopped by someone saying that high flange hubs were better for track use and low flange for the street. The argument was that HF was a stiffer ride than the LF. Since knowone really could measure that statement, it was accepted. Most of my bikes back then frequently had HF hubs.

I did put a pair on a 2010 bike a couple of years ago just to get to ride it.

I keep them for the older bikes with bright rims. I have never really gotten use to dark rims anyway. However, I have accepted them. @
SurferRosa you know this bike. Thanks for your responses.

The tan tires tend to be accentuated with the black rims and the black tread. In this case the spokes are black too along with the hub. The hub in this case is like an in-between flange.
