I have found a pair, new, from a shop, for £1040 ( Campag which seems to take £150 off their initial price ).

Is this a ridiculously good price for this wheelset - i.e should I buy them now?

Very light (for clinchers), very stiff and seem to be pretty reliable based on what I've read online. If they do go bang you'll be faced with a very large bill to repair.

Your post is quite vague - what are you requirements? Just the bling factor, or do you race at a high level?

Neither, but a wheel upgrade on my summer bike is long overdue. I have had two years of the Quattro's and although they are fine, I want more now from a wheel set for that bike. Looking in the region of 1k for a clincher wheel set.

I initially wanted a deeper rim, 40 / 50, but I am realising now there is perhaps more to be gained from less weight. There doesn't seem to be a happy medium, aero wheel sets seem to weight more, lighter sets are a shallower rim. I have been researching this now for a few months and the Fulcrum XLR 50 seems to fit what I want, 50 mm depth yet still light, and available as a clincher. I like the R-Sys but they retail at £1600 which is a hell of a lot. That said I know people who rid them and they are supposedly awesome.

As for bling again I am not really fussed, although anything I buy will be an improvement on the quattro's as I have never really liked the way they look and although they feel fine to ride I am confident the frame / my climbing will benefit with less weight and more stiffness.

So at the moment it is looking like Fulcrum XLR 50's or Mavic R-Sys SLR. I am open to suggestions though.

202 Firecrests are £1,636.07 on Wiggle, and they're a quantum leap ahead of the R-Sys.

I'd rather ride Aksiums than R-Sys, and I'd take the Zipps over both.

Have you had a bad experience then with the R-Sys?

Had a look at the Zipps I do like them. Found a set of 2014 Firecrest 404 clinchers on Campag hubs for £1500 new which seems a good price again online...

If you're expecting measurable gains (average speeds, Strava segment times) above your existing Quattro's you are likely to be disappointed. I've ridden various wheelsets and I've concluded at my level (regular club cyclist) that the most important areas to differentiate between wheelsets are the 'feel' and the 'look'.

Light wheels will feel nice and snappy on hills and when accelerating, but shaving 100-200 g from your wheels will not suddenly add 1 mph onto your average speed or knock 10 seconds of a 1 minute climb. A deeper, but slightly heavier, wheelset might feel a tad less lively in comparison, but you'll struggle to measure an tangible difference in average speed or climbing speed.

Spokes can be expensive and hard to find.

I would go for some 50mm wheels, most of your rides are pretty flat so you'll see benefit from the aero factor while giving away almost nothing up the hills. However I would say as above, they don't make as much difference as they should for the money. Ironically an aero helmet will probably save you more watts than any wheelset and better kit, I.e properly race fit and an aero helmet would be better likely than a whole new bike that was aero and Enve wheels.

I read somewhere that an aero bar made one of the greatest drag savings compared to other expenditure.

Obviously not the chocolate type wink

Aero helmets or racey positions don't carry the same coffee shop kudos, however.

I've had 808's, 404 FC's and am currently running Stinger 4's on the race bike, of them all the 808's sounded best, there's not much between the 404 FC and the Stinger 4 but the HED has nicer hubs/better lacing.

There is a genuine difference between "proper" aero wheels and stuff like the R-Sys, which given the section of the spokes probably qualify as "improper" aero wheels.

You get that tail-wind feeling above 20mph, and it gets better the faster you go.

= if you want to go fast, go deep, and go with a rim design that has spent time in the wind tunnel.

I'd get some Flo30 for training on/raining and some second hand Stinger 6's (or deeper) if you are racing in flat country, 4's if you are heading for hills/mountains.

Friend had a pair and had a couple of spokes snap, PITA to replace. Now has some Enve 3.4 no problems at all

If you're looking at the R-SYS I'd go for the new Fulcrum Zero Nites or the Campag equivalent : http://www.bike-discount.de/en/buy/campagnolo-sham...

Not quite as light but a fair bit cheaper, probably more reliable and they also have no horrible shiny aluminium brake track wink

Otherwise the Aero 38 from Wheelsmith?

For an all round solid wheelset off the peg there are loads of deals on Fulcrum Zeros at the mo, they're light and bullet proof. If it were my money I'd stick £6-700 that way and get a set of 40mm cheap carbon clinchers. I have a set of deep Zipp's and have borrowed some Chinese wheels, there is not as much difference as people would have you believe. They are all crap(ish) in the wet and they all flex to some degree. (404's, 808's and Chinese do with me anyway)

Aluminium brake track - it's worth it to be able to stop.
I have some full carbon 50mm tubs and a set of Dura Ace 7850 50mm clinchers. The Dura Ace wheels are sublime. Ally brake track stops, the extra oomph on the flat or downhill from the deep section profile is noticeable and the all up 1590g weight means they are hardly heavyweights.

I cant see myself swapping those out for anything in the short term.

I have R-sys wheelset. they are great wheels. With the exalith surface braking is superb. I'm a chunky rider at 85-90KGS and I have not found an issue with flex at all. They have 1 small characteristic, they are quite slow wheels once you get around the 22+mph. the spokes being round aren't very aero and you do notice it. I have noticed that at high speeds 35+mph sometimes you can feel a high frequency vibration which I think is the air buffeting around.
it's not an issue, just a characteristic.

I sold my 7850 C50s just before my fall, lovely lovely wheels.

If they were C35s I would've kept them but with a little'un my free time this year would be limited for time trialling etc and so the plan was to get some hand built all rounders.

Then I broke my hip!
