Salsalover, 35 mm is a great rim IMO, but would keep hyperons, for looks, performance and reliability. I have boras as well, and even in the dead flatlands of Florida, sometimes opt for hyperons.
I also have the mv32t Reynolds, 32 mm, great rims, and would prefer them above all if they where campy, since, like it was posted earlier, reliability and cult performance is great. They have dt240 hubs which are not shabby though, and weigh 1040 grs., quite lighter than the 35s that are coming.
Regardless, don't sell the hyperons, they look great on ur c50, will look even better on c59 ad10 and based on your location, seem like a perfect choice.
By the way, wiggle has the 35s for around 1850 US dollars.
Hy Willy, yes indeed the Hyperons are also my favorite carbon wheelset.
Yes the Boras feel faster, and are just a tiny bit heavier, but, as my riding is mostly on hills, the Hyperons are the most suitable ( or the Record/OP for Alu clinchers ) lighter to accelerate, no cross wind drag, that could be a problem up on the hills or descending.
That's why I am so tempted by those new Bora 35, they seem to be as light as the Hyperons, G3 lacing, better aerodynamics, external nipples and a better braking track, what's not to like ?
My Cosmic Aluminum set is a 35mm so I will experiment with it before fully deciding, but hélas that one is a lot heavier than the Boras.
BTW, I have already enough money on the "bike fund" to order the C59 AD10 and I got a good deal from Mike, I just have to decide if I want to place the order now and receive it in september, or wait until December and then receive it on March for my birthday....
