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
