The initial point still stands - why don't bike manufacturers/shops tell people what those weights can be, without making them jump through hoops to either find a review online, or get the guy in the shop to cart out the scales?
Giant for one seem to think it's the responsibility of the shop:

How much does this bike weigh? It’s a common question, and rightly so. But the truth is, there are no industry standards for claiming bike weights—and this leads to a lot of misinformation. Variances exist based on size, frame material, finish and hardware. And as bikes get lighter, these differences become more critical. At Giant, we believe the only way to truly know the weight of any particular bike is to find out for yourself at your local retailer.
