Very lightly used, excellent condition, Carbon Felt B12, 10 spd TT bike. Dura-Ace front and rear derailleurs. Upgrades: Ultegra cranks, 3T bars and shimano bar end shifters. Will include original bars. Zipp 404 wheels NOT included (pre-firecrest dimpled) but can negotiate if you would like them too. I have a variety of saddles you can choose from as well as disc wheel covers if you’d like that too. Used only a few times a year for road race TT’s. Retail was $4000 for bike.
