REPLACING MY CANNONDALE HABIT SE CRANKSET

[JPHG31]

I am the proud owner of a CANNONDALE HABIT SE 2017.
I am very satisfied with this bike but I'd like to change the SI crankset by SRAM crankset.
I asked Cannondale who told me it is technically possible and to visit my local Cannondale dealer.
This one told me it is not possible, he offers me to switch the SI crank arms by Hollowgram SI crank arms.
Anyone can Help?

Your shop is mistaken. It has normal PF30 bottom bracket and normal chainline. Very common. Buy any SRAM 30mm spindle crankset and it will fit straight in.

They may have thought your bike had PF30A-83 bottom bracket and wider Ai chainline like Scalpel-Si, F-Si, SuperX. It does not.

I replaced today my Cannondale SI crankset by a Sram X1 with no issue, everything works fine thanks!
