I gotta disagree here. I can order Genesis parts any day of the week, and the distributors actually have them. Try buying TNX parts at your LHS... Specifically the individually packaged TRF suspension parts, or the individual spur gears.

Genesis also owns the 'Hardest to get parts for at the LHS' segment. I go into my LHS asking about Genesis parts, it gets so quiet, you can hear crickets chirping.
