Context is a 2011 Cervelo RS road bike with a 10 yr old Quarq Cinqo (not being used for power anymore) that I am considering upgrading.
Front chainring is pretty worn and I am considering the possible upgrade paths. Undecided but interested in Force eTap shifting, and trying to figure out if there is a path to get there in steps, or that requires an all in jump from where I am given 10 to 12 speed change.
If I was to upgrade in a big bang I am still confused as to what component selection dictates the other. As best as I can tell the dependencies are:
Shifters (Force eTap derailleur/shifters) dictates cassette/crank (Force XG-1270 12-Speed Cassette / 22 GXP Crankset), which then dictates bottom bracket (GXP Team Bottom Bracket 68/73), plus the Force 12-Speed chain, and a new freehub for the rear wheel + trainer.
Assume there is no way to delay the shifter upgrade if I make the move to the 12 speed cassette/chain. Is the crankset 12 speed specific? Can I upgrade the front chainring/BB as a starting point to get through the winter and then add the rear drivetrain/shifters in the spring?
