You can even keep a spare or two on-hand for when the inevitable happens.
I didn't say that it was impossible, just that it is often difficult to find rims with the same ERD. When a rim can last as long as 10+ years, you are often looking at many model changes and many differences over the intervening years.
Suppliers often change the available rims as well. QBP, for example, may carry Velocity Aeroheads one year and only A23s the next.
