Our side rack plates are on the market for several years and they proved very well, robust and without any issues in everyday use.
When I got my first 690 Enduro, I also got Touratech pannier racks for it and I wanted to mount Wolfman Expedition Dry saddlebags onto pannier racks. I quickly realized that I wasn't too happy with how bags fit on rack hoops - hoops themselves were just not enough to support the bags, in my opinion. So I designed plates that fit into the hoops, providing much better support for soft bags.
Quickly I realized that I can use those plates in different ways - to attach Rotopax can or Tool tube.
Since Touratech mostly use standard rack hoop dimension and same tubing for all their pannier racks, plates could be used on variety of other bikes with Touratech pannier frames.
Over the years, I implemented several changes to the design, usually to offer greater versatility.
In the latest design update, I slightly changed mounting points on the plates. High quality Wurth clamps are still used, but there are no holes on the plates anymore. Instead, there are slots all along perimeter of the plates. This way, clamps can be positioned more freely. Also, unused slots can be used as tie down points for soft luggage.
Next, some holes are left out. This provides more "meat" on the plates, so everyone can adjust them to their needs, by drilling holes exactly where needed. Holes for Rotopax mount are still there, so it can be mounted in several positions.
These changes aren't much, but I feel that already good product is improved a bit more.
