here is the stock clamp. Notice the clamp's band is full.
Here is the new clamp
And it's weight
And here is a shot of a cut out I did in the stock clamp. It still weights too much even with that chunk of aluminium taken off.
Im not sure the diameter is really 30mm. When I tighten it up, the band closes entierly and both ends touch together. I need to tighten it quite good to prevent the seatpost from slipping.
Here are my racing wheels, handbuilt by my friend and forum member LouisN: Stans crest 29er, sapim lazer, alu nipples and american classic hubs. The nude wheelset weights 1440g.
The weight shown includes the tubeless valves, rim tape, rotors and rotor Ti bolts.
Rear wheel, 142 x 12 axle
Front wheel, 100 x 15mm axle
KCNC razor 160mm rotor and Ti bolts

FWIW - I tried superlight rotors on my Scale 900SL build.
They work great on the scale, not so good on the trail. Worse than the poor braking performance, the hand fatigue and noise were awful. Was running them with Hope X2 race in my case.
I have been riding those KCNC rotors for an entire season with my avid XO brakes. They were my racing wheelset only and I put arround 30 races on them in 2013, all Olympic Cross-Country style races. No problem so far. They do not brake as good as other rotors though.
