I am patiently and hoping that someday we'll have a Trek Supercaliber clone. Its a stretch, l know but maybe someday. They have Hightower clones, Spark clones, Stumpjumper clones for instance, so why not a Supercaliber?  What do you all think?

Doubt it.  Would need a bespoke shock.  Unless you're going to totally change the shock / linkage design, in which case what's the point?

Good point.

I saw what looks to be a Trek Supercaliber clone on AliExpress. This is it, right?

This one has been discussed already, it is more like a epic evo clone
