Aye, I know it looks trendy and cool to use deep rims just like the pros, who's sponsors get to plaster their names, etc in yet another location on the bike. But I see no need for me to use them, plus those I know who have ridden with them grizzle-n-moan about side winds.
I've recently built a bike and used Kysrium sls clinchers at around 1300g per set. Bike comes in at 7.7Kg, with the only carbon item being the seat post and sti levers. I didn't want carbon rims, nor carbon spokes so at the time, the Kysriums seems to be as high as I could go in the Mavic range.
I'm happy, the rims are low profile so I don't have any issues with side winds catching the wheels and the wheel set is the lightest I've ever owned.
