So I discovered this damage to the fairly new B67 on my around towner bike today. I'm not sure how it happened, maybe a clumsy drop against something sharp? I hope it's not vandalism. The cut looks fairly deep. The back rail of the saddle frame is directly under the area. I was thinking all I can do is trim away the avulsed leather material and treat it with some leather cream. I use Obenaufs. I don't want the tear to spread and cause the seat to sag.
