Not really sure what you want to know but I have a set on my Niner. I haven't put a lot of ride time on them though. The bike is at Halters right now waiting on some parts. Feel free to check them out if you stop in the shop in the next week or so.
Strength and durable you will get for sure with these rims...They are pretty wide at 28mm...I had em on my old Cannondale and really enjoyed them...If you have a choice I would suggest using brass nipples as opposed to alloy
