I have the same Greenfield rear mount kickstand on my commuting bike. It works much better than the kind that is bolted to the chainstays in the center.

I love having a kickstand on my commuting bike, which is heavy as a tank anyway, so how minds the extra weight....it makes gearing up in the morning easier...the bikes stands better in the bike rack at work...its very useful when I stop to add or shed layers of clothing to deal with rain on the way to or from work.
