The KLICKfix Box Racktime bag is a durable case mounted on the rear bicycle carrier. The case is equipped with the Racktime Vario adapter, which ensures simple and secure installation. Baskets, bags, and other bicycle accessories with this mounting system can only be used on special Racktime carriers that have distinctive holes where the adapter pins are inserted. The Racktime Box offers satisfactory capacity and can easily fit a helmet. The case is waterproof and features a lockable closure, allowing secure storage of personal items. The German company Rixen & Kaul, owner of the KLICKfix brand, was founded in 1988 by two passionate cyclists. In its first year, the company developed the KLICKfix handlebar adapter, which defined its future direction. Instead of annoying and bulky straps, a stable and user-friendly adapter for mounting bicycle baskets and bags was introduced. KLICKfix is now the most widespread quick-release system for bicycle attachment. When developing its products, the company places special emphasis not only on quick installation but also on high durability and stability.
