FWIW...I ordered a JackRoo jersey from rockbros' ebay store. I had never heard of JackRoo so wasn't too concerned about it being a knock-off and I liked how the jersey looked. After ordering, I did a search on JackRoo and discovered a U.S. company in California. I sent them an e-mail asking if the jersey I was buying was a knock-off. They replied that they were looking into the eBay store but that it appeared to be a legitimate dealer of JackRoo clothing.

I've also looked over the rockbros web site and was struck by the amount of Giant products they have there, including clothing, helmets and frames. I'm pretty sure there's no such thing as an aluminum TCR frame sold here in the U.S. but a few internet searches led me to believe that Giant has made an aluminum TCR for other markets.

By the way...I got my jersey and I'm pretty impressed with it. $50 including shipping and it has some nice features. I was conservative and ordered a 2XXL, which turns out to be just a bit too big but it's certainly wearable.
