Not worth it...sell everything you have and buy new Trance with updated geo and 29er wheels if you want them.
Hardly, the wheels will be 400$. like i said, the bike runs great.
Has anyone done a mullet setup on a trance?
Misread your input, thought you have spare forks etc. Anyway you can check GMBN video - they did mullet thing recently. In general mullet bike is best with frames intended to go mullet, they usually have some settings you can change if you change wheel size (chainstay length, bb height etc.).
