Anyone had experience with these cranks, I believe its the same for setup the Oxala MTB cranks.

The system is a hydrid ISIS system where Stronglight have attempted to turn ISIS into a Mega or Hollowtech.

The trouble is that ISIS relies on a shoulder to locate and lock on and this system does not have one and relies on the spaced bearings to provide that function, to achieve this the non drive side has to slide in its housing which I feel might be contributing to the problem with the unit.

The cranks bind tight on install, i've tried pre compressing and respacing and nothing will free up the unit.

Any one had experience with this type of crankset Z Light or Oxala? To me its looks like the designer slept through spindle design 101.
