Hi there, do you have the full specs of the bike - drivetrain, handlebar, stem, seatpost, saddle, model of the zipp wheels, tyres, etc. Why are you looking to sell it and who owned it previously?
Chris, if you look through the other posted photos you'll see that it's spec'd with Ultegra Di2, a specialized carbon hover bar, zipp alloy stem, CGR seat post, 404 Zipp wheels, and S-works Turbo tires. Selling as the rider "lost interest"
Thanks, Chris
