    Yes, depending on a series of variables. the 54cm version of the same bike, almost definitely no problem. Key thing to find out is are the bottom bracket types the same?
  • Everything should fit. Possibly the seatpost will be different if the frames are not the same make/ model. The forks should fit if both frames have a 1 1/8 aheadset, althought the steerer tube might be the wrong size for your new frame. The headset removal is fairly straightforward, refitting will need a press or a vice at a push. The bottom bracket might be tricky, unless you have the right tools. You might get your LBS to fit rhe BB and headset. The cables could be slightly different lengths, but I would replace them anyway (cables are a few pounds each).
    Get yourself good tools. Good luck with the swap.
