I've got a set of Ridewrights on my other ride, Chrome rims and hubs stainless spokes.
The rims and hubs on these wheels Will rust for fun if theyre not looked after.
They are way out of warranty, so I'm not griping but when I contacted them, although they were very helpful, I was told these wheels cant be stripped to powdercoat without cutting the rim. which basically means that they have to be powdercoated as one unit or trashed !
So if you've got saddlebags etc on the back of your ride then you need to remove them and clean these wheels regularly.
I'm quite hacked off about it, what with the price of these things,
Funnily enough my Dna's are fine .. lol

 

Keep them waxed. Waxing spokes is a pain but it's worth the effort.
