Due to some unpleasant events, I need to replace my road bike. I started to contemplate the new and expensive world of electronic shifting and I wonder about maintenance costs.
I am used with the very low maintenance costs of a Sram Force 22 mechanical group set - I only replaced chains, cables and brake pads over many years of riding.

So: what would be maintenance costs for an electronic group set in a long run (5-10 years)?
Thanks
