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 it 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 with simple cleaning. There is also a large tear and peeling on the inside (on the bottom), damage, and multiple stains and tears on the outside. The red gusset part is particularly damaged, so it is being sold as a "defective" item. Also, the condition is judged subjectively, and while I have checked and described the damage in photos, there may be oversights. Therefore, I am looking for buyers who have product knowledge and understanding. Please feel free to ask any questions you may have. #bicycle #frame bag #defective #junk #cross bike #road bike
