I realize there are a lot of posts about kickstands, but I would like to hear from any fellow longtail owners who have used both single and double leg kickstands on their bikes. I have a double kickstand mounted on my very recently acquired Trek Transport but I just discovered that the kickstand is badly corroded on the inside of the plastic adjustable leg extensions and it will need replacement. I'm used to my commuter bike being tippy on the kickstand when I have just a single pannier loaded, but it's just as stable when heavily and evenly loaded as when it's completely unladen; my experience so far with the longtail has been similar. Now I'm thinking about just replacing the double kickstand with a single to save myself a lot of money since I'm not really seeing an improvement in stability. I know some double kickstands allow for easier maintenance but that benefit is a rather low priority for me. So, anyone tried both single and double on their longtail bike and have a strong preference for one? If so, for what reasons?
