About Cervelo S5 9070 DuraAce Di2 Ultegra Crank size 51

Selling my personal bike Cervelo s5. I am selling this because I found a fulltime job and I cant find the time to ride the bike like I use to. Bike has been meticulously cared for. Heavily modified. Clean and no damage. Don't believe me come see for yourself. Never raced. Always kept indoors. No pedals included. [Size 51].
