Hello all, my beloved NuVinci N171b has finally got to the point that it is in need of serious over-haul, unfortunately, Fallbrooke Tech no longer supports it too the point of not even allowing any of their Invaritorc 638 fluid to be sold, so I am on the look-out for that or anything anyone else has found as a suitable substitute Thanks!

Not knowing exactly what their fluid is I am only guessing, but I would try CVT transmission fluid. It is made to provide friction on the variator like the nuvinci.

Enviolo bought all the cycling-related assets of Fallbrook. I thought this might mean the product line was gone for good, but recently I saw a bike with an Enviolo "NuVinci" hub. So they are making stuff.

Anyway, that's the company to talk to about it. I don't know anything else about them.
