There are various KLICKfix fixing methods. For example, one popular option is the Korbklip (basket clip), with which you can easily attach a basket or bag to your luggage rack - just click the two handles to the sides, and that's it attached. Another, but similar method is the Uniklip. Here you adjust the adapter to the width of your luggage rack once, tighten the screws, click on the corresponding accessory, and voilà, you're all done.
Racktime is the result of a collaboration between R&K and Tubus. This system is based on special luggage racks with corresponding accessories, i.e. bike bags and baskets. You place this accessory on the appropriate Racktime luggage rack or adapter, and slide it forwards until the adapter automatically engages. It can be detached again with the touch of a button. Caution: you require both a Racktime luggage rack as well as bags and baskets from this product range, so that everything is compatible.
Another variant is the GTA adapter. The Racktime system, along with the so-called GTA system, are suitable primarily for those who wish to carry both a lateral bike bag and a briefcase or basket. The adapter fits on all luggage racks up to a maximum width of 145 mm. You click the bag onto the side, and the basket onto the top of the luggage rack. Everything is protected against theft with a lock and key.
The final KLICKfix method is called Rackpack. Each product in this line has a so-called Rackpack coupling, which clicks into a corresponding adapter. The adapter is generally attached to the luggage rack, and is generally used for spacious pannier bags with fold-out side bags. You then simple slide the bag onto the adapter, the adapter clicks into place, and automatically and securely locks the bag into place. To remove, you simply pull on the strap that features on these models.
When purchasing a bike bag, a bike basket, or another accessory, you should check which KLICKfix system it is compatible with, and whether you require additional accessories to attach it. At the end of the day, you don't want to buy a pig in a poke, right?
