Approximately 21cm x 25cm x 18cm Gusset: Approximately 4cm Used to store a puncture repair kit, end金具 for transporting the bike, and other bicycle tools. I used this on a cross bike from 2022, but it has some wear and tear, and I'm selling it because I bought a new bag. I think it's still usable to some extent, but as shown in the images, there are stains that couldn't be removed even after a simple cleaning. There is also a large tear and peeling inside (on the bottom), damage, and multiple stains and tears on the outside. The red gusset part is particularly damaged, so it's being sold as a "defective" item. Also, the condition is based on my subjective judgment, and while I've checked and described the damage in photos, there may be oversights. Therefore, I'm looking for someone with product knowledge and understanding to purchase this item. Please feel free to ask any questions you may have. #bicycle #framebag #defective #junk #crossbike #roadbike
