Cannondale Six 13 6 Carbon I bought this bike up to date and have barely put any miles on it. I have kept it in immaculate condition. It is a beautiful bike and has a super smooth ride. I never ended up riding it much because it is just too nice for me to get dirty so it needs to go to any individual which will. I have not rode many race bikes but in line with the forums, this is likely one of the smoothest riding bikes to come from Cannondale. This bike was once also handmade in the us, one of the most last by Cannondale. Carbon fiber frame, bonded aluminum joints. 58cm Carbon fiber Ultra forks Carbon fiber C2 seatpost Tiagra Components Any questions please ask.
