Fork changing=headset changing?
I have a GT Avalanche 3.0 bike which came with suntour front suspension. As I use the bike for commuting I got a set of rigid forks. Both forks have a 1 1/8 steerer tube but the new forks have a slightly different steerer tube bottom profile.
Ie where the bottom of the steerer tube fits the bottom bearing cup. On the suntour it is a taper while on the gusset forks it is a small step.
What do I need to change to get them to fit properly?
I hope this post makes sense!!
