It's only a difference of 5 grams, but please try to get it right

Upstand banner ad from http://www.roadbikerider.com

I saw this ad on the roadbikerider.com website and thought that this looked like a really good idea. Too often I have to lean my bike against store windows, trees etc. So I clicked on the advertisement and was connected to the firm's website, only to be disappointed.

Although the banner advertisement says that the stand weighs 35 grams, the website says that it weighs 40 grams. I know the difference is only 5 grams, but that is about 15% more. If you are going to quote weights to obsessive compulsive cyclists, and make a big deal about the product's weight, the least you can do is get the numbers right and be consistent.
