I have just had a new stumpjumper M4 frame fitted, it replaced a GT one point zero. The problem i have is that the forks aren’t really long enough to go through the frame, hey only stick out about 25mm so there’s barely enough to get my bars fixed onto them.
My questions are:
Do forks come in different sizes to fit different frames?
What should i look for when buying forks if the length of the headstock downtube is 130mm?

Forks generally come with a steerer tube long enough to fit any frame when new. They are cut down to fit the bike they are fitted to.

So any new forks should fit your frame.
