Spokes
may look good, but ...
(Tubeless
vs. Tube-type tires)
Once
upon a time bicycles and motorcycles had spoked wheels. They
looked good. However...
Spoked
wheels are incredibly difficult to keep clean and there are dozens
of spokes in each that have to be regularly checked and adjusted
because they tend to come loose. And, each one of those spokes are
usually mechanically attached to the wheel rims in such a way that
it is difficult to make those connections air tight. On the other
hand, tires in those days had inner tubes that didn't leak (very
much.)
[It
turns out, by the way, that though spoked wheels tended to be
lighter than more solid designs, because the wheel's mass was
concentrated largely at the rim rather than closer to their hubs,
they took more energy to accelerate or brake.]
I
received a message the other day from someone who wants to replace
his modern wheels with ones that have spokes. Apparently he thinks
they look nicer. I have no problem with that, of course. This
person also understood that spoked wheels, unless they are
specifically made for tubeless tires, should be used with
tube-type tires and wondered if there was a safety issue there
that he needed to be aware of.
- Tube-type
tires tend to have catastrophic failures when they are
punctured whereas tubeless tires, because of their
self-sealing construction, tend not to have catastrophic
failures.
- Tube-type
tires cannot be repaired on the road with a tire plug kit. You
get a puncture, you probably have to get a tow.
In
other words, if you want spoke wheels on your horse, for looks,
then unless the rims are specifically made to be used with
tubeless tires, the bike should be a show bike. If you want to
ride your bike on the streets, most spoke wheels are not the best
idea from a safety point of view. [BMW has a spoked rim that is
made to be safely used with tubeless tires.]
