Looking at upgrading my caad13 disc with a di2 groupset.
I currently have a bb30a hollowgram chain set with a stages power meter and don't really want to change them due to the added costs of changing the whole system.
I currently have an ultegra mech groupset that I plan to move to my gfs bike.
Does anyone know if the chain set is compatible with 12 speed? It's become very difficult to find any second hand 11 speed di2 disc groupset .
