I really was convinced of buying some carbon clinchers but i've read some horror story's about failures in descent.. Luckily I only weigh about 129lbs and planning to use 25mm tyres, I assume that would decrease the risk?
I'm a confident descender. Someone who is not will brake a lot more and heat their rims more.
The 25mm tires themselves won't make it less likely to have a problem but running lower pressure will. What happens is the rim wall get hot enough to get a bit soft and the tire pressure pushes it out. That part gets even more brake heat as a result, thus more heat, more bulging, etc.
The ambient temp has an effect too. If it's 100 degrees (F) vs 60, you're that much closer to the temp where the epoxy gets soft before you have even started down the hill.
Doesn't it rain in the Alps in the summer? Carbon rims don't brake well when wet.
My biggest concern are the gran fondo's in the Alps, if there are 20 people blocking my way in the descents, I can't brake the way I should brake with carbon clinchers. And I would probably be thinking all the time about the braking and lose time in the descent.
And yes, it does rain sometimes over there
So my plan is some Dura Ace wheels and light weight skewers. Thanks for your advice eric!
I now have 8000 miles on my 2014 U shaped 38mm farsports. No ISSUES at all. I do keep the wheels extremely clean. I wash the brake surface, as well as inspect them, every three rides. Unless there is rain. Then I immediately clean the wheels. I Keep the brake pads very clean as well. Over all Im very satisfied with this wheelset.
Braking hasnt been an issue at all. In fact Ive gotten very adjusted to how it brakes. The still is very little wheel squeaking , but they are louder when braking. But that seems to be a carbon wheel thing.
After much reading here I've just taken the plunge on a set of the 38mm clinchers from Far Sports.
Have gone for the 23mm wide "New U shape" design with EdHub 2:1.
My question is about tyre size... I plan to buy the Conti GP 4000S II's, but not sure whether to go for 23mm or 25mm width?
I will be using mainly for fast club runs and the occasional road race/crit.
I understand that one benefit of 25's over 23's is the reduced rolling resistance at the same pressure, but is there an aero consideration here too?
Do you guys prefer a 25mm tyre on a 23mm rim, or match the tyre to the 23mm rim?
Is this normal? First experiences of 11 cassettes and not sure how much tolerance there is.

I got your email this morning about wheels enquiry, and replied you directly.
But the email was returned, I donot know why?
Could you please contact me again by another email account?
