Questions you may be concerned about:
Q: Why not add a metal buckle to the spring brake? Is the spring easy to separate from the rubber stopper without the aid of the metal buckle?
A: Metal buckle could damage the rubber stopper under the huge shock in riding, which would be a potential risk. Therefore, we switched to high-quality rubber with high resilience. When the spring is installed, due to the elasticity of the rubber stopper, the spring will be firmly connected to the rubber. Its firmness is no less than adding a fixed metal buckle. So you dont need to worry about the spring will separate from the rubber stopper.
Q: Is the spring easy to rust?
A: In 2021, we have upgraded the zipline spring brakes to 304 stainless steel. The upgraded version is thicker and more resistant to rain, so there is no need to worry about rust even using it outdoors.
Q: Why not build a metal tube into the rubber stopper to prevent the cable from fraying the rubber stopper?
A: Those non-integrated low-density rubbers tend to break under the friction of cable, so a metal tube needs to be built into rubber to add durability. The metal tube is dangerous for cyclists as it may fray the cable, causing it to break. Our brakes use high-density, one-piece, high-quality rubber that is smooth and durable enough to withstand thousands of rubs without breaking or fraying the zipline cable. We firmly believe that safety comes first.
