Si every day. Had a Force 170mm with 39/50 rings before. around 690 with bearings. My Hollowgram SL 172,5 is around 590. And SI is not so much heavier, like 30g? Force is really good but compared to a Hollowgram it's just boring
I was going off of this old but goodie thread about SI vs. SISL thread: viewtopic.php?f=14&t=67162&hilit=hollowgram&start=15
In there members were saying the SI was 660g with everything and the SISL is 580g with everything (80g difference). Since the Force BB30 is around 690g with everything, it looks like a difference of 30g. But I agree that the Hollowgram is more unique and is a better crank overall. One of the reasons I am looking for a nicely used one. Just need to figure out how to make it match the frame a little better. Which goes to the post below now.
the SI and the SISL should have equal stiffness, the SI can be anodized black; nice side-effect is that the cannondale logo's turn out 'ghosted'
The SISL is slightly stiffer than the SI from what I have read? But the SI will be plenty stiff for me. That is for sure.
Do you have any pictures of a SI crank that has been anodized black? Would it turn out to look similar to the black SISL crank, just the letters will look ghosted? I don't know much, but I figure my two options are to anodize or powder coat them. Powder coat seems to offer a little more resistance to scratches and provide longer durability but will need to be baked. From my understanding anodizing is a form of aluminum oxide that is applied using electrolysis vs powder coating using an electric charge to make the powder stick to the part and then baked in an oven.
