Maximum Tyre size on a 2017 Domane SLR?

[smallville8vdm]

Hi all,

 

I am trying to maybe change my road bike to at least a semi gravel bike. It came out with a 28mm and there looks to be clearance for a 32mm maybe a 35. So i am think i have to take it to a bikeshop put the tyre on and see if it fits..... sounds like the right way to do it. But who keeps the not so common gravel size tyres? Or just if someone has the max size then ill just order online.

 

Regards
