Kendog: according to Fallbrook, one advantage of the fluid as a medium of torque transfer is that there is no actual contact between the driving surfaces – they are always cushioned by a layer of the miraculous fluid (or solid, where it is between surfaces). As a result, there should be essentially no wear on these surfaces. It is also worth noting that the hubs have a six year warranty period during which they should not need to be opened or serviced in any way. Beyond that, we’ll see.

Design boasts “fluid that changes to solid under extreme pressures of drive system”.
To a tech like me, this is morse code for downroad maintenance items such as seals, gaskets, and fluid changes.
Also: do the drive contact surfaces tend to groove and loosen long-term, especially under pedal-mashing acceleration?

Yuval: In the US, pretty much any bike shop should be able to order the wheel (to convert your bike) or a Batavus Intermezzo bike (NuVinci hub stock) from Seattle Bike Supply. Some of these shops may sell on the web, but for something like this, it is better to get it from a reliable shop that you have a good relationship with. Ongoing service is always a good option.

Mike: The hub was originally designed to be instlled on horizontal dropouts, such as you describe, using antirotation washers that engage with the long slot of the dropout. The plate that bolts to the derailleur hanger was developed in order to install the hub on vertical dropouts that do not have a long enough slot to engage the original washer. In other words, if you don’t have a derailleur hanger, you don’t need one.

So I was reading somewhere that a derailleur hanger is required for some kind of axel anti-rotation device? Is this true? Does NuVinci provide some kind of workaround for those looking to fit one of their hubs to, say, a rear-facing dropout type of bike that might not have a der hanger?

Doh! Thanks Val, I’ll make sure to correct that.
