The lifeline that can be removed with one touch to prevent the GPS cycle computer from falling out, many cyclists use GPS cycle computers such as Garmin, iGP, and Bryton. Many of these products feature a 90 degree twist on the main unit, but it may come off unintentionally if your hands are hitting or dropping over significant impacts. In particular, aftermarket external mounts are often loose in place. The manufacturer seems to recognize this issue, and the Garmin Edge series comes with an elastic strap. By passing this through the stem or handle, it will be a lifeline to prevent damage or loss of your device in the event of a disconnection. It is indispensable for use in cyclocross and mountain bikes due to large vibration and impact and frequent falls. However, if you remove the Garmin every time you park, it becomes a little more frequent to put it on and take it off, and the remaining straps will be unsightly when you ride it. Therefore, we created an inconspicuous anti-fall clip that can be removed with one touch. This product is an anti-drop clip that fits GPS cycle computers with strap holes and handlebars with a diameter of 1.2 inches (31.8 mm). Produced in a 3D printer with a heat melt lamination system. Made of ABS resin. Easy to install, just snap the C-shaped hook onto the handle. However, due to the shape of the hook, it will not come off naturally when you pull the strap. However, if the brake shift outer is snagged and the hook is inhibited to rotate, it may come off. The rubber straps do not pull up while you are on the road, and the width is 0.2 inch (5 mm) so it does not interfere with the aesthetics of your bike. Meanwhile, the strength is sufficient. For the hook part, a simple tensile test with the force gauge, it was 50N (5.1 kgf) until it is disconnected to the plastic deformation. Instead, the polyurethane coil strap can be cut first. After conducting a tensile test, the following results are as follows: Until the coil has expanded out, 4.9 N (0.5 kgf), 17.6 N (1.8 kgf) straps are commercially available, but they use domestic parts. Edge 840 Solar weighs 89g. Even the heaviest Edge 1040 in the series is 4.6 oz (133 g), so it is too much to prevent your cycling computer from falling out. Compatible handlebar diameter: 1.2 inches (31.8 mm). *Cannot be attached to handle with integrated stems. A strap hole is required. It comes with Garmin, Bryton and iGP but not Wahoo.

Although there is no chance of falling off during a few months of actual use tests or experiments, it may still fall off depending on the size of impact, how it is used, and the conditions of use. In addition, the ABS resin used is widely used for remote controls and handheld game consoles, but it has properties that gradually degrade with UV rays. If used for a long period of time (several years), the strength will decrease and may break. We recommend checking the straps regularly for any damage as they deteriorate over time.
