"Works" in this case depends on what your objective is. It you want your bike to function as it is intended, then my advise is big no. It changes the wheelbase, and adds what 5 pounds to your bike. I'd even say wal-mart pos dual pogostick bikes may work better than ok-hardtail with those on.
Those don't belong to a rider, but if you want to hang around in the VRC forum, go for it!
