All those who would like a single rotor crank for the 13b and are willing to
pledge the $$ toward their purchase please add their name below mine. When
the pledges list is 10 or more we will gather the funds to X-Treme and put
in a bulk order.

It would be nice to gather 20 or more pledges and try to get a better deal.
