What do you guys think? Would you consider this an upgrade? I have the Mavic K Elite right now with only about 350 miles but it is just heavy at almost 1800 grams. I understand that the Speedcific Nobiums weigh in at about 1550 grams and also, the aero rims are a plus. I've seen pics of Mike's wheels and they look sweet.

Any opinion will be greatly appreciated...

I'd consider it an upgrade. my 20/24 set weighs in at 1517g. if you've seen the pics, you've also heard the opinions. they are fairly new. however, Mike has had the hubs out for a while, Am Classic has been using the same alloy in its 34mm rims, and IRD offers the same rims (with 28 and 32 drillings - which makes no sense for an aero wheel).

I think Mike's wheels would be great. However, Ksyrium Elites are great wheels and no one needs to "upgrade" from them. If you want a new toy, go for it, but it isn't going to make a lick of difference performance wise.
