Counterfeit? Possibly. The retailer I bought from is a physical shop and they have a reputation. I have no idea who they buy from, I would guess a distributer. Their product description picture was from Quality Bike Products. But, in this globalized world economy, anything can happen.
I haven't ridden the tires yet. My sole gripe so far was the pain-in-the-ass install. The second tire took two people to mount; there was no way I would have gotten it on without a second set of hands to keep the beads from constantly popping out of the rim. Not all tires will mount on all rims well, regardless of stated specifications depicting a compatible component match. This I know. But, several posters have complained about what I am complaining about, so this constitutes a trend.
Currently, one tire is on a rim without a tube (hopefully) stretching. The other is on the second rim, with a tube, stretching at 62 psi. Hopefully I can go out for a slow test ride tonight.
If the tires' beads pop out while under proper air pressure recommendations while I am on my bike, I'll get super pissed. Heads will roll.
