OFT does little to nothing to change the plane of the handle bar rotation which on the nytro is a lift/drop condition vs. push/pull where your arm strength and comfort position is on a sled.
Both move the bars forward but with the OFT thats all it does....very little rotation plane angle change.
Not familiar with the Rox product, but if it doesn't have a universal in it, I doubt it does much.
