So this is the 2nd pix that I have seen were the sisl2 were not 484 do you think they have "add" material ? and isn't the new Campy over toque close to the same wight?

I weighed my 170mm SISL2 cranks with 50/34 spiderring, the 109mm spindle, the crank arm retaining bolts and the lockring for spidering. 482g. Same setup with 53/39 is 511g.

The pic you referenced also included the bottom bracket bearings and associated spacers and bearing covers.

As far as the link you posted, the Ultra was 560g in a compact (50/34) so 78g heavier. They didn't weight BB bearings at all.

For comparison, my 170 arm is 127g vs the Ultra at 144g..

I love the one piece design of the spidering, great front shifting with Red, super stiff...
