I've damaged 3x sets of mud guards in the past and tried new ones each time. These are the best so far. There's plenty of different hardware and adjustment so if you've selected the right width for your tyres you'd be very unlucky to run into fitment problems. I got the 55 model which just clear tyres measuring 48mm wide inflated. The double stays behind the axle make these guards superior to other options with only one stay and which are more prone to coming out of adjustment.
