Hi everyone - I picked my dream frame, a 1995 Merlin XL. I'm trying to figure out what size fork, headset, and whether a more modern crank like the SRAM 1x (road version) which are GXP or BB30 would fit. The head tube diameter measured 1 1/4" so would a 1 1/8" fork fit? I find that odd because wouldn't most road bikes have used a 1" fork in the mid-90s?

Hoping someone can help shed some light here.
