Harry, et al,

Here's a post that I made last year with "approximate" stack heights for common metric headsets.

The stack heights should be the same for inch size headsets too.

My measurements usually differ from those in 2 different Sutherland's Handbooks by up to a few millimeters.

I wonder how people measure stack heights to come up with all the different published dimensions? Do their measurements include the locknut spacers? Are they using rulers or yard stick (meter sticks)? ;-)

I posted this info on Flickr as a rough guide for measuring stack height:

When all else fails there's always the old trick of just replacing the crown race and bottom headset cup. Tange makes a variety of inexpensive headsets with short lower stacks (around 11mm).

They look like a lot of different classic headsets and are usually available with 26.4mm and 27mm fork crown races.

Tange Passage headsets are far better quality than most headsets used on standard bike boom era bikes.
