I ran a hummingbird on my swift just to see what happened.
went twitchy and cranks looked a little close to ground for comfort.
Brant is right as always but the frame geo needs to take the 450mm fork into consideration like the ragley TD-1 or genesis fortitude
If you run a chris king you could use a “tall” crown race to help.
But also a 470mm fork is close to a 140mm trail fork and worth considering that way round depending on your 26″ frame.
