Look pista goes Naked with Dura Ace and Nitto

Might wanna speak to scorch, he had a simillar problem with his Koga and I think he faced his headtube on both side. Could be wrong but no harm asking :)

Jup, it will never fit. Previous owner had cut the steere too much.
The headset "system" of this 7410 headset works different. It's 2 cups pressed into the frame. While the other system is a cup beneath and a cup sliding over the topplate (difficult to explain this shit haha).

The 7400 headset works like the "other system".
