The Si Hollowgram crankset is a relatively affordable option to save some weight.

do you know the difference in weight between an Si and an SiSL2?

According to Triton Cycles, 602 grams (52/36T) and 494 grams (52/36T) respectively.

I believe there is a third heavier option of a solid (not hollow) chainset on some bikes, which chainset is also called "Si" but not "Si Hollowgram".

That third option is the one I've got, a non-Hollowgram Si. Unsure of its' weight

Those super light parts are an extravagance, really. And a good example of the law of diminishing returns.

Digging the EF colorway, best one of the bunch imo. Mostly black with a little snazzy splash of purple and blue.

I actually like the white branding on the downtube too (vs their recent switch to a tiny "cannondale" on the top tube.) It breaks up the monotony of an otherwise large black canvas.
I agree, atleast this time they didn't hide the "c' annondale :mrgreen:

thats the first thing i noticed about my 2018 SS HM. the C is hidden behind the crankset in about 99% of viewing angles.

Ooh, thanks, that's very useful. 142g difference between HG Si and Si crankarms....I've seen some forums where they mention the top-end SiSL2 arms weigh only around 30-40g lighter, so I'd probably just look for the Hollowgram Si arms. On eBay! On the chainrings there doesn't seem to be much of a difference in weight between 10-arm Spiderings and the Aldhu rings, and even Praxis Works rings are up to 30g lighter. Going to have to think this one through....

More broadly, and if anyone's interested :lol: , so far I've got everything in place to do this:

- GP5000's and Supersonic tubes - minus 208g total
- Dura Ace rotors - minus 72g
- Dura Ace cassette - minus 120g
- Berk Composites Lupina Padded saddle - minus 175g
- Removed spacers - minus 52g

Total: minus 627g, so bike should, when all is fitted, weigh 7.6kg. I paid for the tubes, rotors, cassette and saddle now [already had the tyres], and total cost was exactly Β£450. I basically gave myself permission to spend this due to the discount I got, and I've still got a lot of stuff to sell from my Felt [groupset and wheels, broken frameset]

What's left:

- Handle bar is changed, but I won't know the difference until I pick the bike up later today
- Seatpost - having to wait on this, Cannondale haven't got it on their spares list yet - should be minus 108g
- Cranks - I'll just keep an eye out for now, but I'm thinking 140g-200g-ish.
- Changed bar - minus not-sure-yet, am picking up th bike today

...so could be down to 7.3kg-ish. Cost? Not sure. Worth it? As long as I feel the difference in what is already an amazing-riding bike, then absolutely!

Cheers

Your plan looks good. You could also consider these super light thru axles

Since the SuperSix seems to come with thru-axles without skewer the weight saving might not be worth it. I bought them for my Systemsix and saved about 50g, but those SystemSix thru-axles seem to be a lot heavier than those fitted on the SuperSix.

Just had a Cannondale rep in at work, shown me the new SS. So much nicer in the flesh.
Wasn’t particularly light but it felt very solid and stiff. Sooooo tempted now.

The Robert Axles are still lighter but not by much, around 20gr total over the Evo's stock axles if I recall.

How much do those axles weigh? I haven't weighed both the supplied ones but they don't seem too bad.

Good news though - just picked up the now-slammed SS yay! There's a bit more weight-loss from the cut steerer tube and 50mm of hose/mineral oil removed. But the big win was swapping the handlebar - my Zipp aerobar is 242g, the stock Cannondale alloy one is 320g. A nice surprise saving of 78g :thumbup:
