Interesting, I shall consider that.

I used to only spin up hills, only in recent years have I learned to standing climb, but my bike miles in the '90s and '00s were all on flats or mild hills. Where I ride now, there are big, semi-long hills.

I said previously that saddle up high enough to cause hip rocking was bad. I would add to that, when I'm sitting climbing and have pain, seemingly some muscle because near the surface, just above my kneecaps, that's an indication my saddle is too low, in addition to pushing too tall a gear, but sometimes I'm in lowest gear and the hill is a bit too steep. In recent years, I've learned to stand climb better, plus put bar ends onto my flat bar for more forward hand and body position. You can't get straighter leg than standing climbing, that reduces stress on my knees when needing to mash. However, the hills are long enough, I run out of wheaties, I can't always stay standing, so try to spin some, and if tire there, or start to feel a calf cramp coming on, I'll get off and walk up, it exercises different muscles and stretches out the calf when walking uphill, that really works well, and can get back on bike after a few minutes without cramp.
