Sun Envy Rear rim. Super light weight with eyelet nipple holes to prevent spoke pull through that will happen to the Alienation Deviant and the Gsport Birdcage rims.Source: I've owned two each of the Alienation Deviant and Gsport Birdcage rims: both cracked at the nipple holes and warped with pull throughs.
I ride Alienation Runaway on my flatty, race and street bmx Love those rims
