On One quotes the head angle on their summer seasons at 67.5, what i want to know is which length forks gives you the 67.5 ??
A 100mm fork will give you a steeper head angle than say a longer 140 mm fork ?
Or is the 67.5 quoted using the max fork of 160 mm ?

Thanks you for that
any idea of the angle , running say a 100mm fork ?? .. closer to the 69.5 of the standard 456 maybe ?

i was wondering that too – think it might be about that, but it'd make the seat angle something like 75 degrees! so far forward…
