I ride a hybrid that is proportioned a lot like a road bike (straight horizontal top tube, handlebars several inches below the properly adjusted seat height, 28mm stock tires).

The whole time I've had it (15 months), I have felt like I was leaning too far over to hold the flat handlebars. I have raised the stem to the top of all the spacers. I have gotten a shorter stem (cheap one, to experiment). I have moved the seat all over the place forward and back. I have the seat about as far back as it will go now, and that seams to be the best it has been. It helps balance my butt in relation to my feet, but Doesn't seem to quite be enough.

Has anyone here actually bough and used a stem riser and been happy with the results?
