Hi, just wondering if anyone there has this model bike if they could do me a huge favour please? I am wondering how long the steerer tube is on the fork of a 14" bike (also the length of the head tube of the frame)

Also, which fork is it?

I am looking at purchasing a fork second hand off one of these bikes but am afraid it will be too short to allow spacers on an 18" frame

Thanks heaps guys!
