Which one Marin Fairfax 1 or bergamont 3.5i should i buy?

[Swapna]

My ht is 155cm. I know marin size is xs. But was not able to find bergamont chart. Is bergamont helix 3.5i size small good for me?

Hello and welcome to the forum.
It would help if you could post links to specific bikes. If you can't find a size chart for the bergamot and can't try it I'd just go with the Marin.
