So I'm very comfortable on my Cervelo RS, and so of course am thinking what I can do to change. No, really, I have gotten more flexible in the 18 months I've owned it, and have already flipped the stem. I have a few spacers on it (I'm 55!) and am wondering whether I could tolerate (or learn to tolerate) more drop–I like to go faster unless pain ensues. But the steering tube is cut to my current configuration. If I remove spacers there'll be one of those bumps that look dangerous. I suppose I could try it temporarily? I could also get a negative stem, but that would look weird with spacers. Oh, if this doesn't work it's gonna be because of my neck, which feels okay now but which does not feel like it has lots of room to raise my head back as I ride. So anyone with advice for neck stretching, feel free to give.
