Hello,

I'm looking at a frame from an online seller that has (as measured by the seller) a 130mm headtube with a 170mm steerer on the fork and no headset included with the frame. Stack height should be 40mm.

I'd like to use the Velo Orange Gran Cru headset with cartridge bearings that has a 41mm stack height according to Velo Orange. Are these close enough to risk purchasing at the same time? Or should I verify the frame/fork dimensions first? How sensitive are threaded headsets to +/- a couple millimeters?

My other option would be a Tange Seiki falcon that has cartidge bearings and ~35mm stack height.

Thanks!
