OK, here are my 1st impressions of the rollers.

E-motions appear to be designed by an aerospace engineer where as Kreitlers appear to be designed by a civil engineer (think way over built).

I was surprised how light the e-motions rollers were relative to their bulk. I guess I am used to Kreitlers w/steel frames.

The floating internal frame of the e-motions gets a continuous workout, whether sitting or standing, or sprinting. The floating frame allows for hard sprint efforts that can not be done on traditional rollers. I have yet to need the side rollers as I am able to ride a straighter line during hard efforts than I am used to.

So far my only complaint is the resistance is a little high, even with the magnetic resistance unit turned all the way down. I guess this is due to the smaller drums.

We'll see how they hold up during a season of garage riding ...
