I just ordered a new MTB through the mail (Santa Cruz Bronson). In the spare parts and accessories bag was this weird sheet of heavy vinyl clear stickers. I can only assume they are for frame protection or something? But I can't really figure out where they fit, and the fact that the two "hook" shaped ones aren't mirror images seems odd to me. I doubt I need then for anything... this is more just idle curiosity at this point, thanks!
