Thanks for the video, [MENTION=161860]Mr IGH[/MENTION]. The problem is not that people don't know how to adjust bb7's, it's that they require very frequent adjustment. Personally, the juice just isn't worth the squeeze since cantilevers work just fine for the type of riding I do and don't require anywhere near the same level of attention. While I have no personal experience, people say hydros are better in that regard.
