KASK PROTONE Color: Dark Navy x White Size: M (52-58 cm) Weight: 215g I dropped it once outdoors, and there is a scratch and a small dent on the left side. I have been able to use it for regular rides since then. I don't think there is a problem with normal use, but I cannot guarantee safety, so I am selling it as a junk item. Please purchase with the above in mind.
