I know I asked a similar question a while ago, looking for rim braked DH rims, but the situation has changed now.
I'm looking to build up a Rohloff rear wheel for the tandem.
The tandem came with derailleurs, useless cable disc brakes and rims for rim brakes, but no rim brakes fitted.
I upgraded the brakes to Hope 200mm Mini Monos and also fitted a Magura hydraulic rim brake on the back.
We found the Magura was clogging up with mud too easily, so I removed it again.
We've done a couple of rides on the Black Mountains and Clee Hill and found the discs adequate on their own, so I don't think I will ever want to fit a rim brake again.
So, I'm an XC man, I know nothing about the world of DH rims.
What's good for 160kg of riders on the rear a fully rigid, works well tubeless with Maxxis Larsens and comes in 32h to suit the Rohloff?
I want to build a front wheel on a better hub as well, so same again or something different ?
