Need NuVinci Invaritorc 638 Fluid please :)

Post by LI-ghtcycle » Aug 13 2018 2:22pm

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!
Thank you Justin_Le for your selfless act of kindness! We all are in your debt.

Vision R40 w/3000w MXUS as mid-drive, NuVinci N171B rear wheel as transmission, Silent yet powerful, running 72v 11.6 ah (20s 18650 Li-Ion) to climb hills, tow trailer with zero pedaling when needed!

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.
