Requires different birdcages and and torsion arms to be done right. Z link rotates better... And when we are talking rotation it's not a whole lot.. Disadvantages are chain issues, due to adjustment with gear change, and bird cage timing. Every time you change a gear, you have to adjust the length of your torsion arm to maintain the same timing.
Hope this helps. Andy
