actually, cxp's cost about 30-35$ a rim while open pro's cost 65-75$. open pro's are a much lighter, stronger and higher quality rim with eyelits that go through both walls and a seamless weld. aesthetically, they are much better looking, having a boxy look with a reflective sticker while the cxp's sticker looks like it's from McDonalds and a wear indicator that looks like you have already ruined the rim.
