Kona Project 2 steerer length


Retro Newbie
Just bought a P2 TB fork (410mm atc) from a well known online auction site. But I didn't pay enough attention to the clearly stated steerer length. It is only 121mm.

Would I be right in thinking this will only work on certain of the smaller sizes of Kona mid/late 90s frames? The bare Kilauea frames I intend to build up all have an 11cm head tube.

Does anyone know what head tube length would correspond to a 121mm steerer? Is Anthony still In this parish?

Any help/insight much appreciated.
