Hi,
saturday I went out for a fast training with some friends of mine.
One of them appeared with a Saeco Cannondale Caad 5 (still looking very nice) with carbon HED 3 wheels.
He's very fast, weighs around 70 kg (155lbs I think) and very powerful.
We started our favourite training climb (he was using 53x19 I think), when his rear wheel started dragging on rear brake pads...
I slided behind him, and I saw his rear wheel twisting as if it was liquid! He was forced to open the brake (Shimano), and the drag became less intense. I was really surprised!
Does anybody experienced something like that on HED wheels?
Do Zipp 303 wheels behave like this, in your opinion?

Bye, Benz.

my Zipps have no flex and I weigh 150 lb(7lb winter fat), and I live on 3.7 miles of pure straight up climb.
Even when I jump out of the sadle hard they dont flex, and come to think of it my friends that have the same wheels dont have any problems either .

Me n' a the Brother in Law race a custom built tandam wiv Hed 3 trispokes in it and have not experienced and such problems and We are putting a LOT ov force thro the rear wheel!

I'm quite happy to hear that Zipps have no flex. Considering that I'm very much lighter than 150 lbs I shouldn't experience any problems with them (I'm planning to buy a pair of climbing wheels)...

I have to admit that I was very surprised to see such a bad behaviour from HED wheels... But their flex was enormous...
I forgot to mention they were clinchers... Should that matter something?

Bye, Benz.

Nope shouldnt matter that they are clinchers or tubs.....

Has Your Mate checked his spindle is ok? I have seen these snap before now in a variety of wheels including Hed?

Yeah those wheels are REALLY STIFF! If they are flexing it's probly due to a lose hub. Tell him to check the preload, there probly isn't any. Wheels like that don't flex, he needs to have them checked ASAP.

something seriously wrong if they flex that much

Don't buy the Zipp 280, they are too weak. Go for the 360's with a few less spokes, so +/-120 g heavier, but a lot more durable

Have to say the worst wheels I've seen were on the Morris 8. Absolutely dreadful. Especially in the wet.
