Hey, I ride a bike with no rim brake mounts; it only has disc mounts. Is there an adaptor that anyone knows of that allows you to run rim brakes on something like that? I could design one, but I don't have the materials and ability to create it. All you would need is a strong brake booster with the V-Brake bosses on it and then some type of clamp on each side to attach that to the seatstays. It would probably look like the V-Brake mount on a Le Toy If you know of something like this please let me know where I can buy it. Thanks!
