I'm looking at replacing my entire groupset on the road bike (Felt Z5). Most if not all of the available groupsets are on Ebay. I'm worried about ordering from overseas but a couple of vendors have US based warehouses. This one seems pretty reasonable for price but would really like a vendor with an actual US based store and phone # I can call. I've looked everywhere for a new 105 groupset but Ebay seems to be the only place to go, at least from my internet searches.

Thanks!

Tom
