The original concept behind the design of USS was to improve the riding experience. Given the fact that long-distance touring bikes and gravel bikes often encounter rough terrain with gravel and stones scattered on the ground for tens of kilometers, riders’ arms can become sore from the vibrations.

There is a waterproof trademark rubber at the top, which not only adds aesthetic appeal but also prevents water from entering on rainy days and keeps out dust and dirt. When opened, you can see a high-strength integrated T-shaped screw that can withstand a breaking tension of 2.3T. For riders, it is recommended to open the waterproof rubber seal and apply high lubricating grease weekly. This ensures smoother suspension and enhances the durability of the product. When applying lubricating grease, please loosen the micro-adjustment knob to its loosest position before lubricating. After lubrication, adjust the micro-adjustment knob to the desired tightness for normal use. After applying grease, it is crucial to seal the waterproof trademark rubber cover back in place.
