The Rollerblade Overdrive Frames are made of reliably stable extruded aluminum. They have great power transfer and come in two different lengths, 10.63" (270mm) and 11.61" (295mm). Each can be used for both a small four-wheel setup and a large three-wheel setup. The shorter version at 270mm, has 165mm mounting and can be used for wheel configurations of 4x84mm or 3x100mm. The longer version of the frame is compatible with both 165mm and 195mm mounting and can hold the wheel configurations of 4x90mm and 3x110mm. All of your mounting hardware is included in the packaging and even a tool!
