I'd much rather troubleshoot electronics than try to do tension perfectly, nevermind flushing hydraulic fluid...
I'm pretty handy around bikes, but that final tuning up of both rear and front derailleurs on mechanical bikes . . . it's something I could never get just right.
I'm currently test riding a Cervelo R5 with the new 2018 Shimano DA Di2, for a couple of stories that'm writing. I've ridden on electronic a few times before. I must say that Shimano has REALLY refined the shifting on Di2. I would now put it in the amazing category! Also, I've discovered how to fine tune the system in adjustment mode! in a world - brilliant.I can now fine tune a rear derailleur and get in shifting perfectly.
Also, on the demo bike from Cervelo, it has the newest version of Di2 that has the junction box and the battery in the right hand handlebar tube! So minimal wires running around outside. I often thought that looked strange - $10,000 bike with the junction box and the wires all hanging down under the stem. Looked kind of messy.
I've never been anti electronic - it's just that, well tuned mechanical, was so close, that the difference in rice did not seem worth it. But I may now be sold! I'm in the market for a new Road Bike, probably later on this year - will seriously look at Di2 for the new ride.
