Fitting a Rear Mudguard on a frame which has no Chainstay bridge

Problem

My new multipurpose Cyclocross bike* has no Chainstay bridge to mount the mudguard fender onto.
*Focus Mares Cross 2010 in my case, trying to fit SKS Bluemel 45mm trekking guards.

Solution

When you purchase a new bike you always get a set of front & rear reflectors. If you remove the reflector from the bracket you will find the bracket makes a perfect custom fit for the rear mudguards to fit into. Clamp it to the down tube near the bottom bracket, then use the provided reflector screw to screw through the mudguard (pre-drill first) into the bracket.
