are this really 29" or 26"? does the weight includes rotor? if price is no object the some enve built can be under 900 grams with the right parts
sub 900gram wheelset= 900 grams
that is 225 gram difference
plus the extra weight on the fork and the extra weight of pads and calipers vs rim calipers and pads?
is braking that much of an issue
i ride carbon tubulars with kcnc cb1 brakes and i find the quite aduquate for their job. i do not thik that you can make the rim any lighter specially clinchers.
29in wheel at 943g. And this is for a MTB wheel, it's put through quite a bit more stress than a road wheel, so it could probably be made even lighter.http://fairwheelbikes.com/cycling-blog/custom-bikes/943-gram-edge-tune-29er-wheelset.html
Since your looking for absolute lightest, there are 36g discs. Or 72g for a set. (add ~40g if using centerlock).http://www.innolite.se/sida.aspx?id=50
So your looking at 1015g for a set of wheels including rotors...Not bad, even for road wheels.
EDIT: okay, so I underestimated how light some stock forks are.
Depending on what forks we're talking about, there will be a decent increse. Enve's new disc cross fork weighs 470g
A 2007 XTR caliper weighs 91g..Yes it has pads.http://www.fotos.light-bikes.de/main.php?g2_itemId=2883
Dura-Ace 7900 caliper weighs 145ghttp://www.fotos.light-bikes.de/main.php?g2_itemId=12449
And before you ask lightweight hydraulic cables weighs 19-23g/meterhttp://faqload.com/faqs/bicycle-components/brakes/hydraulic-brake-hose-weights
Why don't you do some research on discs before you start spewing crap out?
