I just discovered a crack in the back rim of my mother's bike and I'd like to replace it. The trouble is that the hub is 40 spoke and I cannot find a 40 hole rim that would fit the bike and would be less expensive than buying a new bike.
However I can find plenty of 36 hole rims that are perfect (other than the fact they have 36 holes).
I was wondering if there are lacings that are safe for connecting a 40 hole gear hub to a 36 hole rim.
I would rather not replace the entire wheel because it would, due to the rather antique internal hub currently in use, likely mean adding a derailleur, replacing the gear-line and replacing the chain, which just seems a little overkill.
