That Dumb Plastic Leaf Spring On Those Fragile Spot Rollik Bikes Seems Like A Cheap Gimmick

This is a stupid idea.  It makes sense as a cheap gimmick, and it is easier to manufacture, but it can't do what they pretend it does, while it surely fucks up the action of the rear suspension overall.  This is a dumb idea.  Working against your suspension and shock tune is not a thing you want.  The Avid people had one good idea: the Tri-Align cantilever brakes, but nobody gave a shit because V-brakes were already almost a thing.  Plus we know those plastic Spot bikes are crack-o-matic torture devices.
