Dear Bikers! I was looking to do something crazy to add to my fleet of bikes: A single speed/fixed gear gravel/mountain bike build. From a bare frame. Problem is I don't have tons to spend, initially....and wondered if there was a decent lightweight frameset to look into to start with? And I mean INEXPENSIVE! No name? Scratch and dent? Whatever...just something that I can put some decent components on to mess around with.

Thanks in advance!
