I have some minimal experience with that one. Bought it to put on a road bike and since it's been winter, the road bike has only been on a trainer. Didn't like it much on the road bike, I don't think it was meant for the leaned-forward position (though I'm new to road bikes so getting used to that too).

I'm going to put the ARS on my commuter hybrid now. I imagine it will be better there where more weight is on the saddle.
