Ultegra 6770 Di2 Mini Groupset

Mini Ultegra 6770 10-speed groupset. All components are in very good condition. I assembled this set from the best parts I could find. A good rear derailleur is very hard to find these days – this one is in excellent condition. The shifters are almost mint, never crashed. Short of new-old-stock (NOS), I don’t think you’ll find better. The set includes ST-6770 Di2 shifters, mechanical brakes, RD-6770 rear derailleur, FD-6770 front derailleur, SM-BTR1 battery (tested and in good condition), ST-6770 new set of original hood covers.
