And therefore your wheels are heavier someplace else...
I was tossing up between Zonda's and Scirroco's (both C17). Went with Zonda's because the rim is just much more highly engineered - MoMag and Dynamic Balance. Hubs are better too. They aren't anywhere near as stiff as my Shamal's but are a very, very good training set. If you can still swap them, I would.
Scirocco wheels are engineered with dynamic balance like Zonda per specs from http://www.campagnolo.com/media/files/0 ... o_2017.pdf
The question is - what is "ultra-linear geometry?
I was looking as Shamals Mille but it's $850. USB bearings must very nice.
I have a set of Shamal C17's too. I must say, don't bother with the Mille (unless black brake track is *that* important to you). Braking on the C17's is superb - far better than the Zonda C17's. The wheelset is only marginally lighter (about 75 grams) but is a metric a**load stiffer. I can easily push both front and rear Zonda rims onto the brake block with my hand - it takes a heck of a lot of force on the Shamals to get anywhere near the block, they really are that tight. USB bearings is a bonus.. can't honestly say I notice that so much over the bearings in the Zonda.
(The Scirroco's don't look balanced at all - unless the extra material is *inside* the rim for aero purposes. That might explain the lack of momag...)
