Here is the reason there is a brake on the back of a 5 wheel skate, it helps the intermediate to advanced skater change from a high rec of fitness boot to a low speed skate boot. It is constructed of air craft aluminum, is designed to be used EXACTLY as it was manufactured. If you drill it, bend it or otherwise try to "adjust it" after it has been bent, it will break in two pieces, unless you have access to a heat treating system! Therefore, these one of kind custom made brakes are available on a limited basis. They are custom designed for each individual boot, as there are many different types of boots, frames and wheel heights these days. From 80mm, to 84mm to, 88 mm, 90mm Think by the time you get to using a 100mm wheel, there will be no need for a brake! If interested contact :racebrake@aol.com
