OK, I dont need anymore answers. I accidently put the question in the mountain biking forum when it should have been in the commuter forum, where I reposted it. The bike is a touring bike used as commuter.I am thinking of getting a ESGE Double Kickstand.
It costs more than $50.
On the other hand, I have just been leaning it up against something for some years now.
Also: Is a double stand like this durable?
