I've bent (7) t-9 rims...they suck
If you guys ride hard,...which I think you do...they won't last long.
I got more life out of the stock rims.
The t-9 gp,..which is the rolled lip version of the standard t-9, is basically a stock rim..maybe a little thicker with the aluminum.. The douglas rims (.190) are the same way.
at least get something with a rolled lip.
