a coworker of mine just picked up a new supersix evo with the sisl2 cranks. as any mechanic would do, he started taking it all apart. here's what he found:

compression plug assembly is 14g complete, vs 50g for the old one. crank individual parts have not been weighed (yet).

Interesting. Looks like they lightened the spindles.

The new expander is great, have to get one of those since I am running the stock expander since the extralite expander was a piece of crap.

Maybe its just me, but doesn't it look like the Black crank fixing bolt is larger in diameter than the green one??
If so, the black one which I assume is the SiSL2 would not fit the Hollowgram crank...
I was hoping this was the quick fix for my SRM dillema... I can only assume somehow the SiSl2 crank will not play nice with the SRM powermeter... would only make sense... nothing is backwards compatible these days.. grrrrrrrrrrrrrrrrrr

Bolt is same diameter, same threads. 12point hole for the 10mm allen wrench lets them take six little slivers out. Bolt is overall shorter, but most of the part chopped off was tapered anyway. Steel washer is more substantial, shinier, slightly less easy to lose.
Spindle is 109mm, a 5mm gain. I am very, very happy about that, as cannondale was simply running their rings too close to the frame for a long time. Now their chainline is inline with road standards. Also plenty of clearance between lockring and pf30 cups, srm should be a drop-in part. Note there is no built-in shoulder anymore, both sides use a spacer. With that, the wavy washer moves to the non-drive side. Inner bore past the threads seems like it's larger, not measured. And, as shown before, holes drilled in the lobes of the splines.
I tested it, bolts are interchangeable, as are arms (onto the spindle).
NOTE- this is NOT the sisl2, but the forged hollow SI cranks, new for this year.
Pics to follow.

What size were the SiSL2 arms and that appears to be 130BCD spider and gears.

That means 110BCD should be even lighter and I am hoping you say they are 175 arms so that 172.5 are lighter. :shock:

I have the Spindle kit on order, was 60-90 days... in the meantime I have got the shoulder cut off my 104 spindle so I can use my 2010 SRM on my EVO now...
the 109mm spindle will offer a standard Q factor so I will be swapping out as soon as it becomes available..
