I have been using and Alfine 8 with my Astro 3220 Tangent kit for a month or so now and all is well still...
What kind of watts are you pulling through that 3220? And what final gearing?
Cycle analyst is set to 6000 but what the peak phase amps are Ii couldn't be sure but probably up at about 8-10k for split seconds when off roading.

Chainring 38 rear sprocket 17 tooth I think....

How is your hub holding up?
This is to express my gratitude to Justin of Grin Technologies for his extraordinary measures to save this forum for the benefit of all.

Still going strong, it's in a new much heavier build and seems ok but then my batteries are on their last legs and I'm barely pulling 2k watts peaks.

The Tangent only puts out roughly human levels of torque but at higher rpms.

New batteries will see how much it can really take.
