How much of mechanical components can one use to integrate with these electronic systems? Will the front and rear derailleurs from the electronic groupset work with my chankset and cassettes?
I don’t have a super helpful answer considering that I’d ask my shop to take care of something like this. However, I wouldn’t be surprised if it’s hard to find something like an eTap derailleur or shifters that are 10-speed, considering that now there’s 11s and 12s. It might be worth upgrading your crankset/cassettes (the latter of which might mean new hubs/wheels?) for wider availability of 11s parts. Hopefully I’m wrong, and you can easily source 10s components and save some cash though.
