Today, when I was riding my A-bike, I've heard some strange sound under my saddle. What I have seen that the thing that fixes the saddle and the rear tube (the plastic none that we have to open/close when we construct/deconstruct the a-bike) is not in its place - it lost it's position and now opening/closing of the fixing mechanism doesn't work. From what I see it's not hard to fix to it manually - I need to use the specific screw, unscrew it then screw it again....
But maybe there is some specific that I don't know. Please advice
p.s. the pic shows it in the right place. I didn't have an ability to photo it today.
