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' weightS6ED wrote: ↑Tue Jul 16, 2019 7:16 pmhttps://www.tritoncycles.co.uk/componen ... set-p15389

bloody hell. £450 for 108 grams????
Those super light parts are an extravagance, really. And a good example of the law of diminishing returns.sgtrobo wrote: ↑Tue Jul 16, 2019 9:47 pmS6ED wrote: ↑Tue Jul 16, 2019 7:16 pmhttps://www.tritoncycles.co.uk/componen ... set-p15389

I agree, atleast this time they didn't hide the "c' annondaleTobinHatesYou wrote: ↑Tue Jul 16, 2019 12:23 am
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.

thats the first thing i noticed about my 2018 SS HM. the C is hidden behind the crankset in about 99% of viewing angles.Js2 wrote: ↑Wed Jul 17, 2019 12:47 amI agree, atleast this time they didn't hide the "c' annondaleTobinHatesYou wrote: ↑Tue Jul 16, 2019 12:23 am

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....S6ED wrote: ↑Tue Jul 16, 2019 8:54 pmI've found this thread about itDaiD wrote: ↑Tue Jul 16, 2019 7:48 pmThat third option is the one I've got, a non-Hollowgram Si.

More broadly, and if anyone's interested , 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 £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

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.S6ED wrote: ↑Wed Jul 17, 2019 1:44 pm

The Robert Axles are still lighter but not by much, around 20gr total over the Evo's stock axles if I recall.floriansantana wrote: ↑Wed Jul 17, 2019 2:01 pmSince the SuperSix seems to come with thru-axles without skewer the weight saving might not be worth it.

How much do those axles weigh? I haven't weighed both the supplied ones but they don't seem too bad.Dan Gerous wrote: ↑Wed Jul 17, 2019 2:37 pmThe Robert Axles are still lighter but not by much, around 20gr total over the Evo's stock axles if I recall.floriansantana wrote: ↑Wed Jul 17, 2019 2:01 pmSince the SuperSix seems to come with thru-axles without skewer the weight saving might not be worth it.

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
