Kind of a moot point since I guess he's not making them anymore, but yeah, I think it was a very good move to raise prices on custom frames. I'm actually really surprised it was as cheap as it had been across the board for so long.
I mean, look at any custom steel road or MTB frame, you're looking at $1500 base price at the VERY least. Typically way more than that, especially for an industry leader, which I think we can agree that Solid was for BMX.
Yes, BMX is far cheaper than road or MTB in general, but if you look at an average custom frame's price compared to the price of an average production frame, as a percentage it's still way below the rest of cycling.
