You have picked up a huge bargain. The spokes are not too tight, they probably require stress relieving (viz. grab a pair of spokes with gloved hands and squeeze as hard as you can). This improves the likelihood that the spokes will last longer. I have a pair of 535s (the previous model) and broke one spoke in 8000km. I replaced and stress relieved all of the spokes and no trouble since. OK, so I'm 75kg and not 90-100 anymore, but I'm convinced you'll be ok.

For that price you can't go wrong. If your son races he won't be able to use them due to spoke count restrictions, just something to think about.

The limit is 12 spokes. These have 16 I think.
Why wouldn't he be able to use them?

Also, in club level racing, no one checks that stuff..

Actually, traditional wheels with 16 metal spokes
and above do not need to have been tested by
the UCI. Wheels can have less than 16 spokes,
i.e. the 12 spoke limit, but may need to be approved
by the UCI prior to use in a mass start race...

Interesting to note that "traditional" wheels are exempt from the rupture
test. Why?
Surely all wheels should have to compy with the same rules.

for $50 you can't go wrong- keep em as spare wheels and they do look flash,
but these rims are *heavy*. I tested these back to back with a set of 105
hubs
and open pro rims and the 540s took a lot more effort to accelerate and even
hold the same speed. They stay true though for a low spoke count wheel,
I guess because it's a strong heavy rim. They came standard on my partners
Avanti Corsa Pro (and no the frame hasn't cracked - see Avanti thread) and
I've seem them on lots of new bikes. OK for training but I'd rather race on
something lighter. Put it this way, once my partner rode her bike with my
open pros, I had to go and buy some new wheels for myself!

Check the hub bearing adjustment too, these ones were too tight from new
and chewed out the cone.

Actually ive been toying with the idea of buying open pro rims & building a
set of race wheels.
Rims seem reasonably priced & one of the lightest on market,,,, spokes end
up pricey once multiplied by the number required....a good hub & these have
to be very competitive . (only a c grader)...any suggestions on spokes &
hubs???
I wonder some times if a $2000 + set are going to be any faster....

About $600 will get you 32h Ultegra hubs + DT 14/15/14 stainless spokes, brass nipples and Open Pro rims (I used CXP-33s).

DT spokes, Ultegra hubs.

Yes, but is it worth it in C? I lose far more races
due to tactical error/positioning than my wheel
choice.

It helped me... but the main reason you build your own is that racing on your own wheels is satisfying whether you win or lose. This is important in the congratulations/commiserations discussions after the race 😉

What sort of tactical errors are you talking about? e.g., missing breaks? following the wrong wheels in the final? I haven't raced all that long, but so far, I've found that my results have correlated pretty well with my level of concentration in the race... bears thinking about.

I guess. I'd rather win on 'cheap' wheels, homemade or
otherwise.

Missing breaks, following the wrong wheel, wasting
energy during the race and dying at the end, poor
cornering leading to lost places.. you name it, I do it.

I'm never focused. The work level I have to maintain
to stay in the race sucks all the power (what little there
is) from my brain. Tactically, all I can manage is "stay
upright!" and "sprint past him.. now her.. and him.."
It's like all my concentration goes into forward motion
and just keeping out of trouble so there's nothing left
for tactics.

Again, I'm not all that experienced in bike racing, but I've played enough sports to know that sometimes it's better to give up a little intensity in exchange for a bit of thinking. If you're currently using zero brain cells in thinking about what you should be doing in the race, it can't hurt to try it out in your next race. Even just a few percent less intensity seems to enhance your thinking ability manifold.

A plan helps as well - being a newbie, my fault is/was to spend too much energy early, so I tried to stick to a plan of minimising time at the front in the first half of the race - then try to put pressure on the group at about halfway (test for a break). There was a risk that an early break would go, but sticking to the plan was the only way to control my (enthusiastic but ultimately useless) energy expenditure in the first half of the race. It also helped in identifying which riders needed to be watched for break attempts...

Ritch.

PS. Crit season soon? I've never tried it...

I investigated the race legaility of these wheels before I bought my bike.
They are sanctioned by the UCI. ->

Good point. Buy locally. I race on Velocity Fusion rims.

That's ridiculous! The races I've lost (lots) have ALWAYS been due to technical problems (I blame my mechanic), frame geometry or someone else in the race.

As of a couple of months ago, junior restrictions in Australia are 28 spokes f/r, 30mm max rim depth, clincher only and rim must not contain graphite,carbon etc.

Have heard that they are goin to change this rule due to the amount of cheaper low spoked wheels.Rule was originally so that the rich kids didnt go out and buy double discs or zipps and smoke the poorer kids. Damn good rule if you ask me.

NOTE: This is for u17 and younger 17 and over can use anything as long as it is sanctioned by uci.
