Maybe. But the world ain't perfect!!Here...from reputable sellers.
I don't mean to instill a snobbery or some kind of distrusting stigma, but just like anywhere else, people can sell you trash here as well, sometimes misleadingly reputable under the guise of being a high-volume seller. But that being said, this place still beats most everywhere else. I will honestly pay a bit more here, than try my chances at other places.
If it's a more recent item, though, there are some "water is wet" plainly reliable retailers. I've turned to Backcounty and other cycling outlets numerous times.
