Yeah the rear Is adjustable and I have it so there is almost no give. The rear suspension I am iffy about. I wanted to buy a cheap bike so I could see what I liked/disliked. All the parts I've bought so far can easily go on another bike if i plan too. One thing I do that I doubt 98% of the road bikers do is there is times where I'll go from 1 level surface to another and it's about a foot drop. This doesn't sound like much but I did that 4 times today and I know if I had a stiff bike i would have felt it. I do agree the power lost from having suspension is there. This is why I want something adjustable so I can find the sweet spot.

At this point If I could find 4' pedals under 45 for a pair I'd do it.
