To learn how to fix would be good because I try and think long had what for front and rear are.
After 2weeks the front fender slightly warped ca.1mm air between mudguards and mudflaps, I could but by loosening the screws and again to fix hindrücken (99.9% new).
The accessory might cleats dazulegen purpose better halt.Hatte yet which. (Not cost the earth.)
Rear must the wheel down otherwise you can not really screw you. Or use an angle drill.
I have also fixed another screw back down raises better.
For Artisan gifted people no problem when mounting.
