What type of ride are you looking for?
Surly Steamroller, Wabi, All City Big Block and Soma Rush are a few good steel options with a nod to general riding.
Dolan precursa and All City Thunderdome are decent alloy frames with slightly less clearance.
Only the BB is available complete and comes in at 1k.
There are still plenty of excellent new frames in production it just depends what you’re looking to do.
I have to admit to being a little curious about the Cinelli Shark...
edit- tomorrow retrogression will be back online making this whole process that much easier!
