The wierd part about this, I have bought some year end bikes, even one from Felt. I guess Felt ran out of 105 FD's, so the bike I got was Ultegra instead. *******s put on an upgrade without even telling me before I bought it.
I serioulsy doubt that Felt would downspec to this level, maybe a little different but not this serious of a downspec. Especially on the F35 which was one of their higher end ready-to-race bikes. I am guessing the shop did this, not to screw you, just over the course of two years swapping out stuff.
