Sore tailbone
Rode 17 slowish miles today on my hybrid, Trek 7000 WSD. Hybrids sit more upright than other styles. Wondering if anyone knows the trick to no pain. I am thinking I need to raise my bars a tad as I've raised my seat already. Would leaning too far or too much cause pain here? I lean forward when riding; in other words, I don't sit fully straight up like one might on more traditional dutch bikes.

You may be too upright if your tailbone hurts. You may want to try a seat with a split channel also.

Your weight should be supported on your sit bones, not your tailbone. I would try adjusting the saddle so your weight is shifted a little more forward onto your sit bones.

Hmm, haven't adjusted the tilt of the saddle at all. Basically my "sit" bones are where my butt makes the most contact when I roll my hips forward right? (laughing at this talk now)

The sit bones are the ischial tuberosities. Not sure how they relate to rolling your hips forward.
The picture in your profile makes it look like it would be hard not to be upright on that bike.
Raising or lowering the seat should be done only to get the proper leg extension for pedaling; your leg should be slightly bent when your foot is at the bottom of the crank rotation.

some saddle designs have a V cutaway on the back of the saddle, maybe one of those will give the Coccyx a break..

I do sit upright but still lean into the bars. Not sure how best to describe that. I guess a good way is that some of my weight is carried in my arms as all my weight is not on my butt since there is some lean. I'm not leaning "Over" the bars obviously but I'm not relaxed in the back because it's straight up. My legs are perfect now, I can get a full rotation and am not totally straight legged. However, compared to when I got the bike and purposely had the seat low while practicing riding in VERY urban traffic-think Hollywood; since then I hadn't adjusted the bars. My arms are stretched pretty far, it feels like that to me anyway. I have a short torso and short arms and think that now that I've significantly raised the seat (barely tip toe touch which is proper fit) I"m thinking the bars need a tad adjusting too. Thanks for the comment and diagram!
