I used these tools for working on my cross bike, but I've since gotten rid of the bike, so I'm selling them. Everything functions without issue, but they are used and in 中古品 (chūko-hin - used condition). There are scratches and signs of use. I don't know the specific usage or sizes well, so please refrain from asking questions. I remember using the chain tool to remove the sprocket. I also have tools for removing the crank, etc., but please judge based on the images.
