^^^ yeah it was probably not the stock tape. The metallic tape was a fancy aftermarket item. Who knows though. I can't really remember what tape they came with, and I used to sell them. Seems like some Treks around then came with some sort of padded vinyl tape. Could have been put on by the LBS at the request of the customer at time of purchase. That was a pretty normal thing. Customer, "I'll buy the bike if you put different color tape on it."
Shop: "OK, sure!"
BTW, this is what I think it is, but in metallic brown, obviously.
