order one and some spokes
Good call on the new spokes. From what I can tell from the
picture, those spoke nipples look to be rusted solidly onto
the spokes. Even if you were able to get the nipples off
without rounding the shoulders, I'd be hesitant to use them
again. Even as a "mild" rider, 28 year old rusted spokes, no
thanks.
You need a 2.15 X 18" rim with 36 holes for your application.
You can either pick up a new "economy" rim and spoke kit
from Moose, Pro Wheel or Warp 9 ($150) or buy a complete
used wheel assembly off of ebay ($50). Just remember, you
get what you pay for.
