2013 Shimano Dura Ace Di2 10 Speed Complete Group Derailleur Shif

This is Shimano Dura Ace Di2 10 speed. It is internal wiring that has been converted to internal seat post battery. Is just over a year old with 2-3K miles on it. The battery life it 1000+ hours since converted to the internal battery as opposed to 500-600 on the stock style battery. It will come with a spare battery along with a charger. Does not include crank, chain or cassette. All other parts are included including the climbing shifter. All parts are in excellent condition. As close to new as possible. This recent set up sold on ebay for $787 and had been wrecked, had scrapes on both left and right shifters. I will let this set go for $850.
