Since I started ripping disc tabs off American Classic rear hubs I've exclusively used DT 240s rear hubs. These days I'm only building wheels for 142 or 150mm frames so let's forget that 135QR exists. What's the lightest hub available and what hub do you recommend*?

*I'm only gonna switch from the 240s to something that's lighter or cheaper while still having a 6-bolt mount with decent disc support and reasonable durability/sealing.
