A few miles into my evening ride on my cable-shift Emonda -- with my

9% grade, that turned at the top to another climb, but a short one.
I tacked a bit, got home and then jumped on the Di2 disc Synapse and
started over. Heavier with fenders, etc., but still a nice bike.
The discs, BTW, don't drag at all. Thank Buddha for that reliable
Di2.

The good thing about the latest Ultegra levers is that there is a
trap door under the lever body, and you can remove one screw, take
out the door and grab the broken cable and end. No more fishing it
out of the lever. This is the second time in 20 years on STI that
I've broken a cable. Before that I broke a friction bar-end cable in
the middle of a tour. I had a spare.

I guess when you've been riding the Di2 setup for the same time &
distance you'll be able to make a more reasonable comparison.

I'm still waiting to break a cable after more than 30 years of using
cable actuated gears and brakes.

I have had the same experience as you. Plus with all of those damn gears you have to spend all of your time shifting and wearing every part out. I almost returned to my 9 speed Campy but couldn't find the shifters after all these years. I cabled my Eddy Merckx last night and installed the chain and respaced the front derailleur to fit the Compact crank. Got a date with the tax man at 9 and then will return and wrap the handlebar tape. I weighed it before the cables, pedals and chain and it was about 17.6 lbs. My Colnago is 19 lbs. so I shouldn't be overweight.
