How does the new Quik Rack Mach2 compare to the old Quik Rack?

It’s the rack you know and love, but QuikR.
14 new patents, modular, light weight, yet heavy duty, NO tools required, easy access release trigger (no more reaching blindly and dislocating a shoulder), quick Add-on addition/removal (did we say NO tools already??), easy wheel size adjustment, amongst other improvements that relieve your bike rack woes.
