Handmade full-frame bag made of X-PAC. Reinforced core inside the body, with ripstop lining. This is a prototype, so the diamond-shaped mesh direction is different on the left and right panels. Unused item. Product Details Fabric: X-PAC Coyote Brown Lining: Ripstop nylon, Navy Right side: Zipper, YKK water-resistant zipper, No. 5, Black Left side: Sub-pocket with zipper, mesh pocket, glove holder Please refer to the photos for the size. The chromoly road bike in the photo is a 490 size, and it's suitable for chromoly 500 size frames. For carbon fiber bikes, it's suitable for frames around size 52 with a gentle sloping top tube. Attaches with a 3mm rubber cord at the top, Velcro at the bottom, and the middle divider is removable, allowing it to be used as a single compartment. A glove holder is attached on the left side, so you can hold your gloves when you get off the bike. The size of the front triangle is shown in the image. It should fit if you measure about 1cm less than the top side of the image. If you are unsure about the size, please let me know the size of your frame, and I will draw a flat diagram to confirm. I have a pet (dog). This product is handmade, so there may be some slight sewing errors. Thank you for your understanding.
