threaded steerer too long

[uptonogood]

Recently bounced off a Lexus 4x4 and need new forks. Found some beautiful Reynolds but steered tube too Long. Am having the thread extended at not so lbs. My question, there is a 2" slim slot running vertically down the steered tube at the top. Can I chop these forks down across the slot. Safely or.is there another way to accommodate this extra tube. Thanks

The slot exists so that if you fit a brake cable hanger for either centre pull brakes or U or Canti brakes the hanger does not twist to left or right but stays centred. The cable hanger has a small tab that engages with the slot when you place it over the steerer tube like a spacer ring, some spacer rings have this tab aswell though for not discernable reason.
If your not using a brake hanger of this type you dont need to worry about this slot so feel free to cut where you like

thanks, that was quick. So you recon it will be strong enough with the slot open at the stem end? cheers
