Got my rear Prolite stand with bobbins and the bike is very stable on it , but the front stand (which I gave back) looked very unsafe. The lower fork legs sat on two horizontal pins each side and these pins could rotate on their brackets . I thought the legs sat on 1 pin each side which fits into a hole in the bottom of the forks ,I'm confused and conflustered . Any body got a pic or 2 showing clearly how thry mount ??
