A customer recently ordered a Rohloff hub from us and we'll be building it up shortly with a Mavix X819 UST rim. This is still one of our favourite hubs and for the right application in mind, it can't be beat. You may never see it at a XC short course mountain bike race but it's been seen at the Trans Alps and we'll be using it at this year's Trans Rockies plus numerous 24Hour events.
Here are some pics of the hub with the 203mm Shimano rear rotor.
We'll be doing a long term review of the hub later this season as we get more riding time. So far, it's been everything we've expected it to be. Most issues we've had are setup issues (ie user error) that once corrected gave us no problems afterwards. We can offer tips for anyone that's interested in one. It justs needs to be thought out at the beginning in terms of installation, cable routing, etc. Afterwards, it's really worry free riding in any condition you can think of.
Update: Well, we've finished building up the wheel and everything went without a hitch. I think one of the key things about a hub like the Rohloff or any internal geared hub for that matter is that tension is equal on both sides of the wheel and this is really important to having a strong and durable wheel. 
Note: We carry spare parts for Rohloff hubs so if you need anything, email us at info@spokewrench.com. We currently have spare cables, shifters, different size cogs, oils, cleaning fluid, cog removal tool, etc. We don't have any rotors in stock but can get anything you need. Just let us know.
Rohloff have recently updated the look of the hub shells. The production
SPEEDHUB 500/14 hub shells now have lasered graphics as opposed to the
decal that previously resided upon the hub shell. The red Powder-coated finish is being discontinued and will be
replaced by an elegant red anodised version. The hubs look very nice. It comes in 3 different colours now, black and red anodized and polished silver.
We think the hubs look great and very sharp.
