fwiw, got my merlin about 16 years ago and it's fully compatible with most everything available today. BSA BB, original campy groupset was 10 speeds, those hubs though are good for 11 and now 12 speed. 27.2 seatpost, standard 31.8 stem clamp, etc.
Dura Ace AX, Shimano 600 AX, and Adamas AX only lasted about three years. Getting parts for those or Campagnolo MIAGE OR Veloce 9-speed now can be hard and/or expensive.
Like someone up thread said, about he only thing you can do is buy plenty of consumables whilst they are still available.
Cheers
