2010 Cervelo P1 for $750. Is this a good price?

Originally posted by audiojan The price is reasonable as long as it's well maintained and in good functional order. It's not a fantastic deal, but also not a bad one. The assumption that you need a 54 just because your road bike is a 54 is completely wrong… First of all, there's no such thing as size denomination standard… Basically, a 54 could be called a size A and would mean just as much. Then add that there's no standard how a frame is measured, so even if you look at the geometry chart, a 54cm may not mean the same physical dimension when comparing manufacturers, common measurements are center-to-center, center-to-top, center-to-virtual point, virtual point-to-virtual point… And all that before we even start taking about bike fit. Even within the same brand, you might very well use a 54cm road bike, but could need a 51cm or 56cm for that matter, tri bike… It all depends on your fit.
