@briwasson. I just found out I don't have enough posts to send a PM. I measured the head tube length and it is 14cm. I am guessing a threadless fork steerer tube would need to be at least 21-22cm long. I'm not convinced a 1 1/4 steerer tube and headset will even fit, but I guess it might. Santana customer service insisted it would fit when they tried to sell me their new threadless 1 1/4 steerer unicrown fork.

Anyway, lemma know if you might have a fork that fits. Thanks!
