Convenient pocket for quick access while riding. Popular with the slim fit for road bikes. Modeled in May 2023. It has evolved into a hybrid type that can also be used with dowel holes. Mounting on fork column is a float structure to create a top tube bag that is not affected by the handle ring. Watch the video below for a unique strap installation. Attaches to top tube and stem (fork column) Convenient for storing your smartphone, food, etc. The unique waterproof coated fabric material is welded together instead of sewing to make it completely waterproof. This unique technique allows the material to be welded together without sewing with threads. Original design perfectly aligns to the angle of the fork column In addition, when attaching to the column spacer, you can use 2 straps to reduce bag swing. The upper belt can be removed if the stem is lowered to the bottom without spacers. We created the bottom stiffness and Velcro shape to stabilize both flat top tubes and round top tubes. Water-resistant zipper is used, so it can be used in light rain. The zipper handle can be pulled with just a finger in the pull. Especially useful in winter gloves. It has a hole to allow cord to pass through when inserting a spare battery. If you do not have a hole for the first time, please use a cutter along the groove. The R250 logo on both sides is reflective material. Excellent visibility from night cars. The core material is incorporated throughout so it does not lose its shape. Yellow inner fabric for easy visibility of contents. For ease of use, the inner dividers were not included. If you attach it to the top tube with dowel holes, we do not use the Velcro on the bottom of the bag. The position of the dowel hole is based on Cannondale and Giant. May vary by make, year and model. Dowel bolt is not included. The bolts with a 0.2 inch (5 mm) pitch are the same bolt for the bottle cage, but the head shape does not stretch out of the head.
