The only other way to protect yourself would be to purchase with a credit card. If there’s a problem with the bike that the store will not correct, your purchase can be disputed with the credit card company. I’d view that as a last resort though, because if a problem is barely perceptible, and the bike store can’t duplicate the problem, they are not going to be pleased when you dispute the purchase. It’s a burned bridge type situation.
It's also possible that the op has unreasonable expectations. For all we know their definition of a major issue tracking to the right would be imperceptible to many of us. Could be a real problem or some princess/pea fussiness.
