These pads were designed by Kool Stop to fit seamlessly in Mafac style pad holders. Despite its anachronistic looks, the use of modern rubber compounds makes this pad far more effective than the original. All of Kool Stop's rim brake pads are made domestically (Portland, OR). Featuring a wide variety of models, compounds, and features.Kool-Stop International Inc. was started back in 1978, in Oregon USA. While making friction components for industrial applications, the owner Richard Everett, began supplying a few compounds to the bicycle industry. After creating the first bicycle brake pad that had an internal frame and an air cooled heat sink, the small garage based company started to build a name for itself.
