Last time I had horizontal dropouts and mudguards I used the little SKS emergency QR adaptors (which are meant to release your front guard if you pick up debris) on the rear. This meant when I had a puncture I could just pop them out, get the wheel off, repair and pop it back without having to adjust the guards .
I'm sure a man of your talents could make something similar to work with those GB stays.
Maybe a rinko pin before the brake so the rear half of the guard can come off?
I have that on my rando. Doesn't work so nicely I think. Especially not with gloves in cold weather imo.
BUT yes. I am totally doing something ghetto rinko for the rear mudguard. Was it you that share those magnetic rinko style mudguards?
