I purchased this item in 2021 on Amazon as a spare for my 3-roller trainer for indoor road bike training, but I never ended up using it, so I am selling it. Although it is unused, it has been stored at home, so please refrain from purchasing if you are concerned. To prevent any issues or product substitution, returns and exchanges are not accepted. I would appreciate it if only those who understand this would consider purchasing. #RoadBike #Bicycle #SHIMANO #Shimano
