As the owner of a few pairs of forged 2-piece wheels that I daily on fairly crappy roads (pretty sure DC will give NYC a run for its money), how do you propose they leak? The forged barrel is fastened to a forged center via hardware instead of it being a solid billet but the barrel is the same... 3-piece wheels, sure i could see how they leak but modern 2-piece are no more maintenance than any other wheel (except for when it comes to cleaning the dang things)...
