Hi,

Can anyone advise me on what the seat tube size is for a 1994 Fire Mountain, specifically the area of the front derailleur?

Promise to ask for a set of vernier calipers for Chrimbo :D

Cheers....

I've got a 28.6mm High band mech on mine. And I think the seat post is 26.6mm

My girlfriend rides a 94 Fire Mountain, and the seatpost is definitely 27.0mm. I remember the size because it was a real pain finding a decent retro post in that size.

right measured the internal diameter of the seat tube and came up with 26.6mm. I sold the Kona post that came with the frame, this was also 26.6mm.

Thank you. The 28.6mm external diameter was what I was after.
