  1. Hi,

    Someone at www.oldroads.com asked recently who or what HR Pattern
    is/was as seen on a number of hubs.

    Lo and behold I was cleaning the front hub of my BSA the other day and
    the legend "hr pattern" did appear.

    Anyone know what this is?

    A manufacturer?

    A Standard?

    Dear Z.,

    Possibly intended for a half-radial spoke pattern?

    On old roadsters? I don't buy that. Halfradial doesn't really become even
    an option until fairly recently, with hugely dished rear wheels.

    Dear Jasper,

    The original post mentioned that the same HR was found on a BSA
    motorcycle front wheel, while Sheldon's article mentions that the
    pattern was used on Ford Model A's.

    Looking further, I found "HR pattern"

    .. . . in British railway lamp auctions, probably an abbreviation for
    some famous railway (GWR is Great Western Railway to the railroad
    folk)

    .. . . in some kind of sheet metal statistics, but I couldn't find what
    it meant ("hot-rolled" led nowhere)

    .. . . and in all sorts of useless heart-rate links.

    HR might also stand for "half-round pattern" (the profile of a hub),
    for "Hub Rear Pattern" on the bicycle (but obviously not the front
    wheel of the BSA--unless BSA was being cavalier), or some company's
    name ("Holmes-Rathbone pattern"😉.

    Here's the inquiry that the original poster refers to:

    "Can anyone ID the hubs that are stamped "HR Pattern, Made in England.
    I keep running across them."
    --Warren

    "Nope."

    "But a couple of days after first reading this, I looked at the front
    hub of my "BSA" guess what I found?"
    --Chris Holmes

    http://oldroads.com/d_eng_ra.asp?OQID=20465&QuestionNum=20465&RID=0

    "Half-radial pattern" doesn't sound too likely to me, either, but
    neither do the other possibilities. I'm still puzzled.

    Cheers,

    The "HR pattern, made in England" on the bike and BSA hubs might
    somehow relate to what's called the BSA threading of 1.370" and 24 tpi
    for hubs:

    "Miche Hubs and cog-carriers use Italien threading which is 35mm*24tpi
    (1.378 inch), while Shimano, Formula, Suzue, Phil, etc. use BSA
    threading 1.370"*24tpi - which translates to 34.798mm*24tpi. Also, and
    i hope i'm using the correct english terms here, the thread angle on a
    BSA thread is 60 degrees, radius 0.17mm, while on ITA it's 55deg and
    0.14mm."

    "These differences are tiny, and as you said, an italian threaded cog
    (Miche or Campy) will thread on a regular BSA hub, but as you can see
    the italian thread diameter is slightly larger than BSA. This reduces
    the contact area, and could very well increase the risk of a stripped
    hub."

    Neither of which are bicycles.

    I don't think BSA threading was ever indicated with 'HR Pattern', though.
    At least I've never seen it.
