That's mostly because the people operating the machines are intern monkeys
instead of highly trained professionals, the machines mostly can't do
proper tensioning, and there is no touch-up truing after the machine
phase.

Also, there is no incentive for manufacturers to do it right, since even a
badly undertensioned wheel will usually last out the warranty period and
doing it right ups costs by a large factor.

For the first question, even "dedicated" production lines are geared to
speedy production rather than careful wheel-building. "Trained
technicians"? What good wheel-building takes is a little time, and
reasonable technique.

A machine-built standard wheel will be true at first, but the spokes are
far too loose, and are not stress-relieved, and so will fail quickly.
This is not prejudice, but observation.

As for which ones do better, one would hope that the fancy "boutique"
wheels costing over $1000 per pair would do better. For me, though, that
is an untestable hypothesis, since I can build my own wheels for a small
fraction of the price, and they last a very long time.

I think the reason machine built wheels have this problem has been
adequately discussed in this forum. With the decreased number of
spokes in wheels these days, the problem has gotten worse, spoke
tension needing to be yet higher than previously. High tension causes
spokes to twist from thread friction which is proportional to tension.

When spokes twist, a machine does not know about it and doesn't know
what to do about it even if it knew. When spokes cease to turn in
their nipples, machine adjustments to tension cease as well, and the
machine goes into infinite loops of measurement and spoke twisting.
To avoid this time consuming and wasteful effort, spoke tension on
machines is set low and there you have it, not properly tensioned.

To make up for the low tension, most wheels are assembled with some
manner of glue in the threads so that while riding such loose wheels,
even when repeated slackening occurred, spoke nipples will not unscrew
to go out of true. It was Wheelsmith using a Holland Mechanics wheel
building machine who came up with the idea of SpokePrep thread glue.

Also, please tell us how untrained, inexperienced, unsupervised and

I think we have seen adequate proof of that here, from riders who
report success in their first set of home built wheels. Following
instructions on "how to", humans are able to sense spoke twist and to
correct for it so they are not limited as current machines are. They
can make wheels as tight as they need be.

I think the real issue isn't machine built wheels, but how far a robotic
wheel building machine can get a wheel to what it should be, for
installation.

Cars, washing machines and computers, (I don't consider an electric
motor or a compressor complex enough mechanically for a valid
comparison), all need a person to make the final adjustments, before it
is ready for use. Same goes for a bicycle wheel, the machine might be
able to get it 90% there, but a mechanic taking that wheel and making
sure all the spokes are tensioned properly, and stress relieved
properly, and making sure all the components are working 100% will take
even a cheap wheel from being [censored] to perfect.

There are dealers where the wrenches make sure every bicycle sold is
properly adjusted 100%, and that includes making sure the wheels are
trued and spokes tensioned and stress relieved properly, and in that
case the wheel should be pretty much as good as a hand built wheel.

That there are undertensioned wheels being shipped with many bicycles
is apparent from the many complaints we read here and from the bicycle
shops I have asked about their wheels. The better shops around here,
manually tighten and true wheels of bicycles they sell.

I haven't bought any bicycles recently and haven't tested any, so I
can't tell you which brands have loose wheels. On the other hand, I
am aware that most machine built wheels are built on the two Dutch
machines, Holland Mechanics and BMD.

You seem to change the subject from whether machine built wheels are
failure prone to which bicycle brands have machine built wheels.

I am writing about that subject and do not claim to have made a survey
of bicycles that have such wheels. However, most of them have such
wheels if they are not exotic wheels with few and unconventionally
shaped spokes. Such wheels are by their nature difficult to build by
machine and their high cost easily absorbs the extra attention of a
manual wheel builder.

wheels do not exist. The machines of the two companies I name are in

So, Holland. A machine maker. The devil incarnate, with regard to
wheels. Now, I seem to have forgotten, from all the re-published
opinions, what facts do you bring to the table today? What brands
of wheels fail to observe proper building techniques, and which ones
are coldly put together by inanimates objects.

These machines are the savior of wheel building in that they can do
this at a far lower cost than manual assembly. Wheel building is a
tedious low speed operation in the hands of humans for production, so
the advance to machine building is a positive step. Right now, all
these wheels need is a final manual tweak and stress relief. Both of
these operations can be added to existing machines.

well, since you're fighting shy of citing specific examples, let's
approach this from the other end of the spectrum and *rule out* a couple
of instances for you instead:

1. shimano r540. perfectly true - as they have been from the day i
bought them. straight out of the box. about 3k miles.

2. mavic cosmos. perfectly true, as they have been straight from the
box. commute wheels. bought them last april. about 2.5k miles.

now, of most of the "expert" hand built wheels i've also owned over the
years, only one pair have been anywhere near this good - the pair i got
from the bike nook in san francisco. everything else has required
attention almost immediately and regular touch-ups thereafter. i've
also seen these pre-built wheels go to heck, but only after the local
wheel monkey has wrought their usual havoc. that's why i made sure both
mine were still in their box & untouched before purchase.

conclusions:
1. people that know how to build wheels well are /mighty/ thin on the
ground.

2. pre-built wheels are much more trouble free. and for a consumer that
wants trouble free riding and doesn't have access to a proven wheel
guru, frankly, name brand pre-built is the way to go.

You can buy whatever wheels you want. But too many people here, and on

at least you're now qualifying your position and limiting it to

whether it's built by machine or by hand, low quality is still low

Are there any machines that build conventional high-spoke count wheels

When I was a kid I had a home working job lacing bottom end steel rim
wheels, I was paid 20p per wheel and did about 6 or 7 an hour. At today's
rates that would probably cost around a quid a wheel.

In a decent wheel the cost of lacing is negligible.

It isn't only low end wheels that are built on machines but rather
most non-esoteric ones that use elbowed spokes. The difference is
that the purveyors of these more expensive wheels realize that they
need final tightening and truing before shipping them, so they do
that. I know that the bicycle shops in my area do that to wheels on
bicycles they sell.

As I mentioned, Wheelsmith was one of the earliest in the USA to get
such a machine and I witnessed the problems they had. It was the
loose spoking that got Spoke Prep into the mix. If you look at DT's
web site, you'll see the even offer spoke nipples with such an
adhesive in the threads.

Those of us who have built durable wheels for a long time without
spoke adhesive know that it is not necessary because a nipple on
tensioned spoke cannot unscrew. It is only when the spoke becomes
slack from road impacts that they do so.

I am certain that you cannot properly tension a wheel (even 36-spoke)
ready to use in the machines of today. That is why Holland Mechanics
and BMD are pursuing that feature that is easily added to their
equipment. Wheel lacing is what the machine does best. If you watch
one in use, you would be amazed how fast a wheel is laced up and ready
to true. It is the "Robot" that has the problem and it can be fixed.

That's too bad, the lacing machine is a real boon to wheel building
and delivers a wheel that could be ridden (although not long.) I
doubt that they can lace a wheel nearly as fast as the machine can do
it. However, from the lacing machine, it's a short manual process to
make a good wheel.
