I didn't mean to insinuate that everyone should ride with 9 cm of handlebar drop, because we all have issues. But getting the weight off the shoulders and straightening the back (bend from the hips) can benefit anyone. A straighter back leads to a straighter neck, which means less strain and pain.

Case in point: I test-rode a Trek 7100 that I'd just built up, to see how comfortable a comfort bike could be. Even with the handlebar a few inches higher than the saddle, I was leaning on my wrists. The steep seat and head angles of the 7000 series comfort bikes make proper weight distribution extremely difficult.

When I turn 90 I'll order mine with a 300 mm setback seat post. Or get a Navigator.
