Not sure about BB7 but My HS33 started being really good then it started to fail confused I took a closer look just needed re-bleeding, there fore id say the HS33 is a great option. But a wide disc won’t be beaten for stopping power. I know from my downhill bike that hydraulic discs will always beat hydraulic rims!!
