I could fix this by buying a fork with a longer steerer, but I don't like the available options. (This is a road disc bike.)
If any of you believe I'm thinking about this the wrong way, please speak up. I'm thinking I will lower the top-tube, seat tube junction by a few mm while maintaining the top tube angle to give myself a bit of extra space to work with on the head tube extensions.
By the way, the reason for the long head tube is that I'm very tall--6'8". My fitter recommended a 234mm head tube.
Make your own fork. Another option if you only need a couple of cms more steerer length is to add a section to it's top. Sleeve the add on for strength and alignment. Since the bearing alignment issues will still be on the original length and the stem will overlap the added on section I think all would be good. But I'm sure some will find this option to be wrong... Andy.
