Mounts easily onto my Salsa Journeyer using the given bolt spacing and the bag length is perfect for wrapping around the stem. I took a star off because of difficult packaging of the instructions to the bungee strap and no bolts to mount the bag. The bag is made of soft material, so I could see someone over stuffing it and possibly causing knee issues if the bag bulges out. Although I have a 60 cm long wheel base bike so it is not an issue for me as my knees come up near the end of the bag. The bag width is about the same as my top tube, which is what I expected. Just enough for my carrying purposes (bars, suntan lotion, day-use stuff).
