Those rims are fine, and stay with the origional size rims!!!...Also, make sure you find out what kind or bearings they use in the rims and get yourself a few pairs to have as backups, and leave a pair in your bike at all times...I have seen a few guys with aftermarket rims chew up wheel bearings and be in the middle of know where and cannot get any bearings...If you have a pair in your trunk at least you can get someone to install the bearings!!!
Hey CrotchRocket, what do you think causes the bearings to be eaten up in aftermarlet wheels? My friend has a Blackbird and we both went with aftermarket wheels, but he chewed up a set of bearings in his rear. He sent the wheel back because he thought something was wrong with it, but they said that the wheel was fine. But after 7,000 miles, I haven't had any problems. The only difference is that I ordered my set with a cush drive and he didn't.
