Unless you swap the stock pedals on the Grando (possibly the regular newer 520’s as well) to clipless there is always going to be toe overlap. The pedal overlaps the front wheel by 200-500 mm depending on size of frame. My 2022 Grando is a size 57 frame with Stock ProWheel 175mm crank and stock Welgo Flat pedals with toe clips, front wheel set is stock 700c 40mm. When the non drive pedal is in the 9 O-Clock position (vied from the non drive side) there is 30mm of overlap without fenders. Yes adding fenders will make even more overlap resulting in an even greater amount of toe overlap.
