Long story short--I want to do more road cycling to supplement ultra-distance running and need to re-aquire a bike. Despite my cycling friends insisting I buy new, I am more of a value shopper and would rather pay $1000 for something that was $3000 5 years ago versus getting what I can get new for $1000 today. My current best options are a 2002/3 Litespeed Vortex (Lotto team edition) with full Dura Ace, some of which is what came stock, and is overall in 9/10 shape. Having ridden the bike and inspecting the cassette/rings, it looks used but well kept and rides and shifts perfectly. I can get this bike for $1100. Option #2 is a 2006 Giant full carbon TCR C1 with mostly Ultegra that is in 8/10 shape and firm at $900. Option #3 is a 2008 Full Dura Ace Spec Tarmac that could be had for $1700. Have not ridden that one but let's assume it is in 9/10 shape. The wife would not appreciate the price tag of #3, but like I said I am going for value. I welcome anyone's opinion. I would like to eventually do some centuries on whatever I buy. Thanks!
