4. This front-end conversion search is based on bearing inner and outer dimensions ONLY! Stem length may vary from machine to machine making some combinations unworkable. As a result of front-end conversion, rake and trail may be altered, adversely affecting handling of the vehicle.

This has been helpful recently as in the past I had to do a back and forth between the All Balls catalog and K&L Supply catalog and SKS . NSK....
It was an ordeal but I got good at it .

The problem with cataloging stem lengths are many fold . Where do the upper threads start ? What clearance is there at the bottom ? Measure the frame or the stem ? Actually test the stem in the bike ?
I'm sure there are other issues to confuse but in the mean time getting the membership to include bikes in their sig line so a simple PM and a measuring tape could get you an idea would help . I'm something of a major offender here because my rolling stock (and not so rolling) changes by the week if not day .Even then I "think" I have 13-15 bikes around here .
