REFLECTOR: Nosegear Forks - Correction

[Greg Poole]

Hi Jim,

I was specifically looking at the aluminium fork in light of its'
recommended replacement rather than the leg proper Jim. My kit - a STD RG
E - was despatched late '98 and I believe (hope) most of the problems in
terms of nose leg gussets, mounting, temper and bend angle were sorted prior
to mine being shipped.

I well remember your previous & regular mentionings of the problems you had
with your fixed gear front leg....obviously still a sorepoint for you.

Best,

Greg.
