I just mounted it to the B10. I couldn't get the reg VR one over here in germany, so I ordered the DA version. It's not that close to the seat post like it's supposed on the DA but it looks goin fine.
I was thinking to dremel the inner shelf away but wasn't sure if it's still strong after doin this.

Tried drinking and it was easier than it seemed.
