That sounds very much like the variation Rotor qoute. So I concede that it might work after all. But it doesnt sound like a nice set-up to run fixed. Especially when you consider the fixed drivechain automatically aids you in the dead zone anyway. If the effect is small on a geared bike, it must be tiny on a fixed one.

(FWIW I wanted the 3D cranks firstly, and bought the q-rings as an interesting addition)

get yourself some rotor RS4X - same function as the egg ring but you can run the fixed with no change in chainlength
