I nearly immediately changed out my pedals, saddle, and bars (and really the only problems with the pedals are the clips; the pedals themselves are fine for a generic pedal.) The stem and wheels are fine, again for generic components. Some people have complained of creaking bottom brackets, but I never experienced that.
And now my son rides on the the wheels, stem, and pedals. The generic components on the KiloTT aren't as bad as the rep they've earned around here.
But yeah, I'd immediately ditch at least the pedals, saddle, and bars.
