I was previously a Spearfish owner and we had a Facebook group that was pretty nice. Lots of Spearfish related stuff, people selling or trading parts. Bike specific questions and help. I think we had 122 members.

Anyway I just moved up to a Horsethief and found there didn't seem to be an existing group so I created one.

Anybody that's interested can join up.
