Rb's were discontinued yeeeeeears ago so won't pick one up new, and you will be very lucky to pick one up 2nd hand! I have 2 but wouldn't sell them because they are suck gold dust. Fresh products made a similar style lever blade, (which some people didnt like) I loved it because it wasn't as far reach from the bars and still offered extra, I think Todge may still have some, you will have to PM him (if you can) as the website is no longer running News article from a few months back I loved mine was sad to see it go. You will have to wait forever, and probably pick it up by buying a whole brake, I had to do this recently because I wanted to try the full carbon RB lever body as well as the lever.
