Trying to find replacement wheels for Alexrims DM21 Doublewall 559X18 6061T6
I have a diamondback tandem bike with Alexrims DM21 Doublewall rims. The rims have also show these numbers: 559X18 6061T6. I live on an island and my current rims/spokes have rusted out. I'm hoping to find replacement rims, but it appears these same rims are not available online. I'm trying to learn about rim sizing, but want to make sure I purchase the correct rims. Can anyone provide a few links to rims that would work as good replacements? I don't want anything too high-end as whatever I purchase will also likely rust in a few years. Thanks for your help.
