welcome to china, land of the counterfeit fakes.

ordered a 20" alex DH19. contacted a few sellers to get the ERD so's i could
calculate spokes. nobody knew what an ERD was. they just sell stuff. emailed
alexrims.......they don't make that model in 20". website only lists 700C and 26".
ok....maybe the usa salesman doesn't know what they sell in foreign markets?

well, my alex rim arrived today. looks nice. but. the label says "ETRTO-559x18"
oops. if the chinese are good at anything, it's copy-n-paste in photoshop.

it would seem somebody somewhere used a chinese production JP brand "power
circle" DP25D, and switched labels.

note the exactful similarity?

POWER 双层车圈|自行车|铝圈|铝合金车圈|DP25D-淘宝网
正品特价ALEX DH19亚猎士20寸 26寸 32孔36孔v刹白色 黑色V刹车圈-淘宝网

guess i'll just build it up and see what happens. what could go wrong, right?
