Do we even know for sure if this is an actual LE, and not just a regular Zaskar?
Most all the repro decals out there on e-Bay say "Zaskar LE", just like the ones on this bike - You could stick 'em on anything.
I've had 2 Joytech hubs apart, one of them a Joytech freehub, both from a somewhat derelict bike that was left out.
Both were fine (including the freehub mech), after cleaning and re-greasing, and I used them to build new wheels.
So, I guess YMMV.
Those BB threads don't look that bad, just clogged with solidified gunk -
Just patiently scrape them out with a dental pick, and a new one will thread right in :)
