SRM Chainrings choice and swap

Hi,

I would like to buy a srm (fsa gossamer) but I have some doubt about he choice of the model. Compact or standard.

I ride most of the time using 52x39 but make some stages in mountains and 50x34 should be usefull !

Because compact is 130x110, my understanding is I can swap with other chainrins like 52x39.

If I choice standard model, this is 130/130 and will be not possible to have less than 38 for small chainring.

Can someone confirm my understanding or not ?

Many thanks

You are correct. With the compact SRM you can go “both ways”.
