Awesome, just awesome.

Only thing left to do sadly, is to ride the shit out of it.

Whats up with these new Si cranks?

are they just hollowgrams with differnt branding?

yea, thats the hard part! Only done shorter rides so far, so the stem angle and length is still TBD

also need to install smp composit. Just got 2nd hand from italy via ebay

This is RAAD. Seriously tempting - thought I'd made my mind up to build a Ritchey Road Logic but now...

Pretty much, it's the heavier Hollowgram crank arm (Si is the budget version of the SiSL2), but with an adaptor to allow normal chainring to be fitted.

Meaning you can fit those one piece double chainset on it instead of the adaptor + FSA chainring, despite that, it is still pretty light at 540g.

awesome

No, they're not hollowgrams at all. They're forged cranks with a channel down the back, visible here:

They are plain old forged cranks - think omnium like in construction that happen to fit the Si hollowgram axle.

For some reason I kept calling it a Hollowgram cause it a branding.

Still at 540g without axles, it's pretty light, lighter than Ultegra even with the axles.

Huh, cannondale does actually still call them HollowGrams though

confusing of them

Those are 740g with rings

Whether they call it Si or Hollowgram it's still confusing as fuck.

Here's the skinny.

Original BB30 crank, 144m Q:

Si [2001, silver, ltd edit. black, all discontinued]
SiSL [2007, black, discontinued]

New BB30/a crank 144mm Q (or 147mm if you believe a Cannondale doc, but I don't.)

SiSL2 [2013, black 109mm axle]
Si hollowforged [2013, black, hollow, 109mm axle]
Si forged [2016, black, forged non-hollow, 109mm axle]

In that case, the Hollowgram name is basically branding rather than an indication that it's hollow.

More like solid gram em i rite he he

But yeah from what ive gathered upgrading to force/3d bb30 would be solely for looks. Red/3d+ for weight as well

Well, before the Si forged crank they all were hollow...

I reckon that's just a bug in teh internetz; the data sheets I've seen refer to the Si forged crank as Cannondale Si

Still a good product as it takes the same hardware as the Hollowgram cranks, spidey, OPI and whatnot. Great for MTBs.

very glad I got my Supersix while the Si were less shit than they are now!

Even thought it's not hollow, the Si isn't shit to begin with, especially since they share the same axles as the higher end one, once the FSA ring worn out, you can always fit the Spidering on it.

They still do both the Si and SiSL2 hollow cranks. The forged Si crank is their way of getting shouty and crappy fsa crank arms off their low spec high tier bikes.

Such as the FSA Gossamer, the world's most inappropriately-named crank.

I was building a weight-weenie six-evo hm a couple of yrs back and without knowing the specs assumed the Sisl2 was going to be the lightest between itself and Sram Red, especially as it was £700....but when I looked...Red was about 50g lighter and half the price.
I never understood the big deal about Sisl2 and hollowgram.
Anyone care to enlighten me?

God I miss rep...

I'm not sure there's been a Red crank that's lighter or stiffer than Hollowgram SL or SiSL2.

But the weight difference is tiny, with the red crank being 60g or so heavier. So might as well call it even.

Hollowgrams just look better, have detachable spider, cross compatible with MTB shiz and IIRC stiffer...might be wrong on that though.

And you can trace their lineage back to this

Which is kinda cool
