Ultegra groupset completely replaced with Di2, electronic shifting.
Shifters and front derailleur are Dura Ace.
Includes sprint shifters.
7.9 kg total weight.

I bought the bike in 2017 (without Di2) and everything except the frame and fork has been replaced over the years.

- Dura Ace shifters with buttons on top to operate your Garmin/Wahoo, very convenient.
- Sprint shifters extra in the drops, also wonderful.
- Ultegra crank 172.5mm
- Dura Ace front derailleur
- Ultegra rear derailleur long cage for large cassette
- Ultegra rim brakes (direct mount) so that 28mm tires fit.
- Vibe stem 90mm...
