I just traded away my Di2 Ultegra Cannondale SuperSix. 15.5 lbs of silk, error-free shifting on Zipp 404’s. The trade was hardly even, but my friend has the bike he’s always deserved, and I have a bad-ace Kestrel and another set of NOS DA9000/Open Pro tubeless wheels.
I just was not totally enamored of Di2. I missed cable shifting, sort of. I felt less.
No doubt, there is electronic in my future, likely wireless, but on steel and not an $8,000 Madone with 105, Di2 or not.
The trickle down on what I want is slow. I can wait, and if I can still ride then, sure.
