Was just down at the LBS and noticed a bike next to the 2005 Felt F2C that looked just like it, but had F3C on the top tube. They said it just came in on Friday in a box marked as an F2C and that the '06 FC3 is basically the same as the '05 F2C. It looked virtually identical in styling and graphics. The F2C is scheduled to be upgraded, (maybe to the current F1C?) and so on.
They said Felt is really ramping up their 2006 production and rolling out the bikes early to avoid the issues a lot of people had locating some 2005 models and waiting a long time (in a few cases waiting in vain) to get their bikes.
