edited December 2009 in Road buying advice
I am after some new wheels for my TCR Advanced. Would like them to ber suitable for sportives & triathlons (Marmotte & Ironman Florida in particular).

I would like them to be:
Clinchers
Alu rims
Not too heavy? (say <1,600g)
Factory look
Relatively easy to maintain.
Budget <£1,000

Taking this into account I fancy getting me some of these:
Dura Ace WH-7850-50mm Carbon Clinchers

Anyone ridden these? Got any comments?

Many thks.

    Appreciate this is 'off brief' on account of weight, but I bought some Pro-Lite Gavia wheels recently, and they're great. They're also 400g too chubby for you though....

    Admittedly I took my life in my hands and bought then from eBay, but you can get them new for £650 or so, I think.

    If you're going to be riding steady-state pieces then you may find that the weight isn't a massive problem, and they seem to be very tough. I don't recommend them for leaping out of the pack like a scalded cat though....

    You should speak to Steve at www.roadacecomponents.co.uk. You can have an amazing set of custom built wheels for that money.

    Steve is an experienced rider and wheel builder, can't get better than that.

    cheaper here 8)

    Have a look on the road section of weight weenies http://weightweenies.starbike.com/forum/

    They chat about such things from time to time. For the Marmotte you just need something light and reliable. It's the tri stuff that will swing it towards the (expensive) aero stuff.

    Marmotte and Ironman Florida are 2 pretty diverse events for one set of wheels.

    You might be better using a general use set of wheels for the Marmotte (what do you train on?) and buying wheels specifically for Triathlons/flat TTs if you do them. Carbon wheels with an alu brake surface are either heavy or can leave you at risk of heat build up on alpine descents and resulting punctures (there have been threads on this before).

    That said the 7850 50s sound like a good compromise if that's what you decide, haven't heard of issues on descents...

    Here's thread on alpine heat blowouts with Zipp clinchers (DAs not mentioned here of course, but nonetheless a similar design):

    yep, I saw quite a few blowouts on the Marmotte from carbon users.

    It almost brought a tear to my eye to see very expensive carbon wheels sitting useless by the side of the road.... 8)

    That is a bit of a worry. The reason I wanted the Alu/Carbon mix was the concern over braking (in the wet).

    Thought these wheels were a good comprimise, not too heavy, aero and looks great. Training wheels are very average. Jalco 270s. In fact average is a compliment. Not been concerned as they do a job and I new I was getting a nice new set.

    I run full carbon tubs and with yellow swissstop pads and find the braking in the wet very good indeed!

    That said, I'll just use my Open Pros in the Alps next year...

    If you've got £1000 and no good everyday wheels at the moment, I would buy 2 pairs of wheels:

    1. Planet X 101/82 tubulars on offer at £499 - perfect for Florida (I'm assuming it's flat!) and other tris and TT
    2. Some good lightweight all alu clinchers for about £350 - e.g. Fulcrum 3, Ksyrium Elite, Shimano RS80, 2008 Easton EA90SLX, whatever floats your boat - perfect for marmotte and all round summer riding

    You've got £150 left for tubs, valve extenders and a cassette for the tri wheels. Jalcos are then relegated to winter riding.

    The American Classic 420's are pretty new out. I haven't got first hand experience, but a mate of mine has a set of AC'S he's very happy with.
    Just over 1500g, a 38mm rim would be a good compromise for your Ironman and under budget at £500.

    These are the white version, but black/red also available

    I bought some shimano WH7850 50mm carbon clinchers as a birthday treat to my self and i would not hesitate to recommend them.Only ridden a couple of times on them because of the lovely british weather but they are smooth and very responsive.

    I got mine for the cheapest I could find them at around £884
