The Tony Pass ThinSkirt
In 2003 Tony Pass
started producing a rim with a radically new design. The upper
part of the rim is the standard 3/4-inch thickness, but the bottom
part is considerably thinner. Tony had noticed that if he struck
a rim with a thick wall, it had a higher pitch than did a rim
having a thinner wall but the same outer diameter. It was reasoned
that since a thin piece of wood is more flexible than a thick
piece, it would vibrate at a lower frequency if its weight was
not too much lower. And, of course, a ThinSkirt rim has a larger
air chamber inside the hoop.
Most rims now being
made by Tony are of the ThinSkirt design. However, he will accommodate
the wishes of those wanting rims with the conventional design.
And, for those owning Tony's conventional rims, he will be happy
to modify them to the ThinSkirt design for a nominal fee.
