I'll do one now.

*sees word Ksyrium in sentence*

Yup, it's [censored].

Everybody here will tell you that 28, 32, or 26-hole wheels are stronger, more durable, weigh less,
and cost less than any of the "expensive wheels" to which you refer. When spoke count goes down, rim
weight goes up to compensate, thus negating any gains you may have had by reducing spoke count, due
to the additional rotating mass. Unless you ride on rollers, you may have an unfortunate encounter
with a pothole or otherwise, thus ruining the rim. Then you'll want to replace it. Proprietary
technology is expensive. This goes for the hubs and the spokes, too.

They do. It's called "racing". If the wheel doesn't blow up spontaneously under the racers, then
it's strong enough for racing use.

More seriously, any oddball wheels (I think the UCI spec is a wheel with less than 28 spokes or with
a rim deeper than x) need to pass a rather odd "burst test" to qualify for UCI approval.

I think it's fair to assume if you're worried about wheel strength, you should probably go with a 36
spoke wheel and sleep well at night. You won't lose any crits or road races over that choice.

what kind of strength? load? fatigue?

damonrinard.comindex.htmOpen ↗ has a bunch of useful comparisons.

Those wheels are bought for looks and not on functional specifications.

Well when if I am going to spend so much money on a set of wheels I would like to quantitative tests
rather than just a companies word for it.

Well that obvious, but when you get down to lower weights design becomes much more crucial. I notice
that Mavic still uses the older traditional wheels for it's service vehicles.

Your village called.... they're missing you.

This is only a partial truth. These wheels are primarily bought to let other cyclists know that one
can afford expensive wheels.

Well that obvious, but when you get down to lower weights design becomes much more crucial. I
notice that Mavic still uses the older traditional wheels for it's service vehicles.

There's a couple of excellent reasons for that, the most important of which is that for Mavic's
neutral support unit, the signature race of the year is the Paris-Roubaix. Wussy wheels need
not apply.

Another good reason is that they are neutral support. Not making assumptions about the equipment
racers might want, they instead provide a sturdy wheel that is all but guaranteed to make it to the
end of the race, if necessary.

Low weight is fun to chase, but is probably counter-productive in most races other than
hillclimb TTs.

A friend just found some gorgeous 28-hole clincher rims in the 300g range. Probably about the
lightest practical rims around, and they have a big "Race Use Only" sticker on 'em. For the track,
okay, maybe. For specialized events, sure. But calculate the number of road hazards you catch on a
typical circuit race versus the number of times the lighter wheels would equal victory (which is
probably a negative number compared to the number of times heavier, more aero wheels would win you a
race, and both numbers are likely zero). Not a good bet, eh?

Ryan: tsk tsk... You mixed the mutually exclusive words "clinchers" and "light". Clinchers cannot be
light due to the extra metal required to hold the tire bead.

The light rims you refer to are Sun M17A's tubulars. 300 grams if that. Add some DT Rev spokes and
some Dura-Ace hubs with Ti axles and you have some sick light wheels for a reasonable cost. Given I
have an unlimited supply of these rims for $10 Cdn each, I can afford to aim for potholes.

Yah, but can you afford the dental bills when the super-rim collapses?

You're convincing me I need a set of these, just for the joy of owning a stupid-light component.

Fabrizio would be pleased,

Actual weight of the M17As is closer to 340-350g. Still pretty light.

350 grams?? That won't do. My rims do not have sockets to save weight. Are you sure these are the
ones you have a weight on? Otherwise, this means in the spirit of weight weenydom, I'm going to get
out the drill press and start ventilating the undersides.
