Following Sunday's mudguard-smashing stick, I've taped up the split plastic, removed the rusty washers from the mounting points, installed a spare set of releasing clips I had and done everything back up again. I haven't cut down the stays; because of the extra length due to the clips, they need to be shortened. So now my back mudguard is wonky to match the front! (albeit radially rather than side-to-side). I might even decide to replace these supposedly black but look brown in sunlight mudguards with silver ones to lighten up the bike, especially now I'm not (currently) using the black rims. Or maybe metal? For the time being, I'll see how the gaffer tape works!
