But when I'm in the 11t or 12t cog on the cassette it slips
On the big ring?
Even when in the big ring and the 11t cog it slips, the chain is coming away at an angle from the cassette to the left (in board) and its riding up onto the 12t.
Uh ok.
You can’t add spacers beyond the narrow preload jobbies to the axle - you could only move the entire assembly which gives you other interesting problems.
So something else is wrong somewhere.
Howard-
Its actually harder for it to slip in the big ring actually, it doesnt slip so much but i can hear more noise. This makes me suspect its the drive side cranks being to far inboard because the chain line looks more normal while in big ring but still not right.
when in the small ring it slips constantly in 11t and 12t

I have hollowgram si bb30 crankset wth spidering installed on my caad10 disc black inc.
Does anyone have experience of having to use non standard spacer set ups on the cranks to get a better chain line?
the crank set has been installed exactly as the instructions here show: https://www.cannondale.com/-/media/files/manual-uploads/manuals/sisl2_road_crankset_instr_1012.pdf
But when I'm in the 11t or 12t cog on the cassette it slips. I'd though it was worn chain or cassette since both were taken from a previous bike. But I've put on new cassette and chain and its still happening.
I've since realised that when in the 11t and 12t cogs theres a lot of cross chain. looking at the chain line i've realised the drive side crank needs to come outboard a bit more to stop the cross chaining.
Even when in the big ring and the 11t cog it slips, the chain is coming away at an angle from the cassette to the left (in board) and its riding up onto the 12t. So to fix this bringing the drive side crank outboard should help I think?
But it's installed as per the instructions...
Is this common to have to mess about with the spacing on hollowgram? Its such a pain in the tits to take the hollow gram arms off. I have all the propriety tools for the cranks set so will take them off this afternoon and try fiddle.
But would like to know if anyone else has experienced similar?
Really thinking about sacking off the frame and cranks now. frame is a 58 incase anyone wants to buy...
