And by their own graphs, it doesn't touch the low
frequencies that can be a problem.

Dear Frank,

Look at those graphs again:

http://www.specialized.com/OA_MEDIA/pdf/Witchcraft.pdf

The left graph shows vibration lowered at all frequencies on the rear
of the bicycle, and the right graph for the front end of the bike
shows reduction at all but three short points

The reduction is greatest around 400 hz, but it's clearly reduced at
lower frequencies, too. Whether it's enough to be noticeable to a
rider is another question.

Cheers,

Carl Fogel
