Racktime is a German company that makes front and rear bike racks or carriers that are versatile, sturdy, and sleek. Tubus, which is Racktime's parent company, has a great line-up of high-strength steel racks. Racktime racks are made only from aluminum, and although aluminum is not quite as strong as steel, it is much easier to work with. Therefore, Racktime racks are very sturdy and more versatile than steel racks like Tubus, due to the manageability of aluminum. Most of the Racktime racks are compatible with the Snapit mounting system.
