All,
I really want to put some disc breaks on my cross bike. I'm a pretty big
guy and the standard breaks really don't cut it for me. Honestly, I know
next to nothing about disc breaks (being a long-time roadie), so I
really want to poll the OBRA collective consciousness and see what
people think. I would like the system to work with my existing shifters
and not be -too- heavy. Any recommendations on what works well?

Thanks
Seth
