Aero wheels for a small light rider

They even climb very well in comparison to a set of lighter, low profile rims i also own.

Do you mean they climb better than the lighter, low profile rims?

I hope not. Because that would mean your fancy, heavier deep section rims defy physics.

Truly remarkable what you can buy for "just" £800.....

No, what i meant was exactly what i wrote.

"They even climb very well in comparison to a set of lighter, low profile rims i also own."

At no point in my post did i imply that the Cero RC45 wheels i bought made me a faster, better rider. I only confirmed that i too had been researching the minefield that is deep section wheels, noted what i eventually bought and gave some feedback as to the performance of them.

I don't think i should have to justify my purchase but because of the tone of your previous posts i'll play the game a little.

I had some money to spend after an annual bonus from work. I just so happened to already own 2 pairs of alu rimmed low profile wheels so i did not see the point in having yet another pair. I like the look of carbon deep sections. I fancied buying some, so i did. I now use the low profile rims for long days in the hills/ mountains when i will get the benefit of them. For other general riding or fast flat rides i use the carbon deep sections.

For the record i am 5'10" and 68kgs, have so far covered 4500 miles this year at an average speed of over 19mph in a mix of club rides and solo. So i don't think that losing lots of weight or training a great deal harder will make a major difference.

I know what you wrote. The clear implication was that they were better for
climbing.

me a faster, better rider.

Good. Because they don't.

This isn't some "game". People come on this forum for information. As for your
assertion that you shouldn't justify your (expensive) purchase, you should.
Readers want to know the pros and cons of products that poster's have bought.

I like the look of carbon deep sections.

Translation: I'm a fashion victim.

For other general riding or fast flat rides i use the carbon deep sections.

Wouldn't it be more economical to use cheaper wheels (ie. Al alloy rims)
for general riding?

If you trash your wheel in a pothole, you can just get another (cheap)
rim and/or spokes and rebuild the wheel.

Or do you like to "show-off" your expensive wheels irrespective of their
suitability?

Freeebsd_frank, please stop posting your ill formed opinions as if they were facts. Give an opinion by all means but don't do it in such a way as to make it seem like it is accurate rather than an opinion. Taking your points in order:

Some deep rims are lighter than some shallow rims.
If 80% of wind resistance is the rider and not the wheel then in cross winds the deep section rim is negligible compared with the effect of the rider.
Not all deep section rimmed wheels are weak.
20 radial spokes are fine, back in the 80's I rode TTs, road races and went youth hostelling on 20/24 spoke radial wheels I built myself without a single problem or without having to true them in over 5 years.
When you say "sealed" hubs I assume you really mean cartridge bearings. Most cartridge bearings are replaceable, the Hope hubs on my MTB have had one new set of bearings in 10 years of heavy use, they did not have to go in the bin. However, my Shimano cup and cone hubs had to be binned when the bearing surfaces pitted.
If you read (and respond to) the original post you will see that the wheels are for triathlon which you don't seem to consider to be racing. Try one, you will soon change your stupid viewpoint.
32 spoke 3x wheels! Please, these are racing wheels we are looking at not touring wheels with a weeks worth of camping gear on board.

Freeebsd_frank, please stop posting your ill formed opinions as if they were
facts. Give an opinion by all means but don't do it in such a way as to make
it seem like it is accurate rather than an opinion. Taking your points in
order:

Don't tell me to stop posting my opinions and while we're at it, tell me which
of my facts or opinions is wrong instead of indulging in personal abuse.

Some deep rims are lighter than some shallow rims.

Made from the same material? That defies common sense and science. Well done.
Can you also say "ill formed opinions"?

If 80% of wind resistance is the rider and not the wheel then in cross winds
the deep section rim is negligible compared with the effect of the rider.

So if it's negligible in a cross wind then it's even more negligible when the
wind is in your face, isn't it?

Many have attested to steering problems and keeping your line in cross winds
with deep section rims.

Not all deep section rimmed wheels are weak.

I never said that they were. The strength of a wheel has more to do with the
spokes, how they're laced, what material they're made of and their number.

20 radial spokes are fine, back in the 80's I rode TTs, road races and went
youth hostelling on 20/24 spoke radial wheels I built myself without a single
problem or without having to true them in over 5 years.

So your anecdote overides the scientific evidence on the matter does it?

Even Campagnolo says that their 20/24 radially spoked Khamsins should not be
used by people over 82Kgs.

To use a 20/24 set of racing wheels for youth hostelling constitutes an act of
gross stupidity on your part.

When you say "sealed" hubs I assume you really mean cartridge bearings.

No. I mean hubs that can't be maintained by the user.

Most cartridge bearings are replaceable, the Hope hubs on my MTB have had
one new set of bearings in 10 years of heavy use, they did not have to go
in the bin.

Good for you. You bought a quality product that you could maintain.

However, my Shimano cup and cone hubs had to be binned when the bearing
surfaces pitted.

Another anecdote. They were defective or you didn't maintain them.

If you read (and respond to) the original post you will see that the wheels
are for triathlon which you don't seem to consider to be racing. Try one,
you will soon change your stupid viewpoint.

If you read my previous post, nowhere do I say that triathlon isn't racing.
Stop making stuff up and then abusing me.

You're a moron who can't properly address the facts and opinions I bought up
in my previous post. Keep touring on your 20/24s. Keep believing in the magical
benefits of your weak radially spoked deep section (and expensive) wheels
so that you don't look like a plonker when riding with the rest of the
sheeple.

The fact is you're a fashion victim with more money than sense, unable to
support your opinion that deep section rims are "better" accept with lame
anecdotes. What do you do when you're found out? Resort to abuse.

Pathetic.
