I'm hoping someone can measure the width of their caliper for me. I'm going to upgrade the brakes on a 75' CB400f and these calipers look nice without being too modern for my bike. I don't want to buy one to find out the width though and possibly have a paper weight. I need something less than 3.500" total width so it will clear my spokes. I can always use a sliding 2 pot caliper but I love the looks of these. If anyone can help I would greatly appreciate it.
