Need help identifying bmx bike I recently got a ton of bmx parts and 2 frames for free from someone on nextdoor. He left the parts at the end of driveway, so I couldn't ask any questions. I'm curious about this race frame he gave me. I put this mostly together from parts in the box. The decals have been removed, and there was only an Answer sticker on the bottom of the frame. I'm hoping the gusset on the headtube may help someone identify it for me

Generally speaking you can tell if a bike is good quality by the attention they paid to finishing it.
So, for example, and expensive bike has the welds ground off and sanded, so that the joins between the tubes look smooth. This also reduces the chance of rust getting in.
The chrome plating will also be higher quality and very shiny (and easy to polish as a result). If the chrome is tarnished and peeling, it's a sign of less attention being paid in the factory.
To me it just looks like a mass produced bike. Perhaps not bottom rung quality, but not the best either.
The weight test is another simple way to tell. Cheaper bikes can also double as boat anchors :)
