Folks,
I've previously written here enthusiastically about the Busch & =
M=FCller Ixon headlight, which I bought from Peter White last spring. =
(http://www.peterwhitecycles.com/b&m.asp) I'm still enthusiastic =
about the light, but less so about the special-purpose fork mount =
bracket that I bought at the same time.
In case anyone else has bought this bracket, I'm appending a copy of =
an email that I just sent to Peter White. I think that it's self- =
explanatory.
