Under four euros including shipping ... I did not expect much, but since it was intended for a relatively light Kinderfahrrad I dared. The articles came from abroad and has it takes 10 days, but at the price I could get over it. The rear derailleur protection itself is gratifying well made, the places where is riveted the bracket to the mounting plate are neat and stable. By snake shape of the mounting plate, the bracket can be attached to many wheels and doing there what he should.
