This is my Mondia single speed. I don't have many problems with the bike, or to be exact, i have a single problem.
Now and then the rear wheel slips out of the dropouts by only a couple of mms. That locks up the chain, so i stop, loose the screws, get the wheel back into place, tighten the chain and screws and keep on cycling.
What could I do to prevent this? Is there an addon i could screw on to prevent wheel from "slipping"?
As you can see on the photo, it's a Campagnolo diagonal dropout, with an adjustment screw.
