The Speedfil Micro-Retractor allows the rider to pull the drink tube up to 24 inches from the handlebars, drink, and then release. With up to 6 oz. of force, the retractor snaps back inside the keeper with no hesitation. The Speedfil Micro-Retractor utilizes a Spectra/Nylon line and has a 40 lb. break strength to withstand even the most aggressive off-road riding. This is NOT just an “off-the-shelf” key retractor. Our partners have spent years designing this product to not only survive saltwater and military applications, but it is also specifically designed to clean itself by flushing out sand, mud and other debris.
