Looks like a custom frame from an artisan builder and it looks modern, late 90s.
I can’t see anything similar on the website unfortunately.Could it be a Brew?
I remember a test in Mountain Bike Action in the late 90's - I'll see if I can find a picture.BREW Bikes LLC
Brew offers custom bicycle and motorcycle frames along with bicycle frame classes.www.brewracingframes.com
Here is the first page of the test in Mountain Bike Action. It is from 2001 - so not true retro
The rest of the pages need a better scan...
The frame in the test seems to have straight seatstays and other dropouts compared to your frame. So yours is probably not a Brew then.
