330.0. "a wheel problem" by NOVA::FISHER () Mon Jun 01 1987 13:20

    I never saw this happen to a new wheel -- or any wheel for that
    matter -- before and thought I'd see if it's a common problem.

    I have a wheel -- UKAI 27x1 1/8 w/o LA, 48 hole -- which has eyelet
    reinforcements on all of the spoke holes.  Most of the grommets
    have broken on the inside of the rim so that the other end is
    floating up and down the spokes (or down actually depending on which
    way the weel is turned).  As a result the wheel has loosened up
    quite a bit and is not as true as it once was.
    
    The wheel is the rear wheel of a tandem and had about 650 miles
    (1 month's use) on it when this happened.  The total rider weight
    for the tandem is 310 lbs so that should not be an unusual factor.
    
    The bike sounds funny when you walk it because the eyelet parts
    ping as they fall.
    
    I took the tire off to see what the inside of the wheel looks like
    and most of the head parts of the eyelets have many cracks/breaks
    with little pieces all over the place.
    
    I got it (the tandem) from Wheelworks in Belmont so I expect to
    get reasonable service in this matter, but is this a common problem?

    w/o LA?
    
    I've seen more than a reasonable share of quality control problems
    with UKAI rims, I'd say that it's probably pretty common. If the
    grommets are broken and/or cracked I certainly wouldn't want to
    be riding the bike when the wheel blows up. I'd take it back to
    Belmont and have them lace up a better quality rim like a Weinmann
    concave or Mavic.
    
    Good luck,

330.2What is the scoop on Weinmann Rims?PEANO::BLACKMon Jun 01 1987 16:0814
    Chris mentioned Weinmann as a "better quality" rim.  I had allmy
    original wheels built in Weinmanns about 10-12 years ago in England.
    One of the formost racing wheelbuilders in SE London swore by them.
    
    When I finally wrecked them (by driving my car under the car-prort
    with my bike on top), I was told that current generation Weinmann
    rims were not much good.  Something about Belgium vs Switzerland.
    
    Are they better again now?  What is the scoop on Weinmanns?

330.3service is A-OKCREDIT::FISHERTue Jun 02 1987 08:0412
    I called them up, they said, "bring it in."  I did and they said,
    "Midday Wednesday?"  You can't get much better service than that.
    
    They are going to rebuild it with a Wolber Super Champion Model
    58.  I've used Mod 58's on my touring bike and been very happy with
    them.  They guessed that the wheel building machine had overtightened
    the spokes causing the problem.  My guess is that there was a flaw
    in the metal used to make the ferrules (grommets) and it could not
    stand the strain.  That does not make me feel overly comfortable
    about th efront wheel but I'll keep an eye on it.  I'll probably
    replace it just on general principals if we keep using the tandem
    for ultramarathon type events (did one 400km on it, more planned).

    The 58 is also a good rim, it was designed for medium to heavy duty
    use like the Weinmann concave. I'd definitely rebuild the front
    with another 58 just in case.
    
    There are two qualities of Weinmann rims I've seen, the cheap ones
    they put on inexpensive bikes, and the top quality ones that go
    on everything else. The cheap ones are no better than anybody elses
    cheap rims. The concave has a reputation for great strength in the
    rotating direction, although if you do ding one it's almost impossible
    to take it out.
    
    That's my experience

330.5final resolutionNOVA::FISHERWed Jun 03 1987 17:429
    Okay, the final story is that They ended up giving me a wheel from
    a Santana in the shop and trading my wheel back to Santana.  They
    said they did not have spokes on hand that were the right lengths
    for the 58's.
    
    I cannot complain about the service.  I'll have to try the rim and
    see.
