I am bad enough with cables, electronic shifting is totally alien to me. I considered old Ultegra, but keen to try something new and save some grams in the process. What makes the new one better ? Look same-ish to me.
Wheels will probably be the last thing I'll get, but feel free to PM an offer
Good decision on all fronts, SRAM Red 22 is good but if I was building something today I'd either get etap (if electronic) or Ultegra R8000.
I have some HED stinger 4 gathering dust if you are keen.
