The post about an uncomfortable saddle in which he referred to "sperm tubes" leads me to think there is some trolling taking place.

Trolling is always a possibility, but he just told me in the golf club thread that he thought trying to hold the golf club without starting a thread first "sounds dangerous". I'm no shrink, but that sounds like a phobia or some ocd thing.

I've often wondered if I were a mod would I feel any responsibility to direct help toward these individuals. Unhinged, drunk and dementia, we've seen it all here. A little sleuthing should ID a family member or responsible adult who could be made aware. Providing a stage to parade their derangement seems unhelpful as well.

For a fixed power output, the cadence with the lowest heart rate was about 60.
But you may not be interested in the cadence that produces the lowest heart rate, but the cadence that leaves you the least exhausted at the top of the climb.

But if you want proof, just watch TdF races on Giro d' Italia stages. You'll see some of them like spinning easier gears seated entirely, some like to stand for long period on harder gears, and still some like to do both - alternate periods of seated easy gears and harder gears standing.

I would think the ideal gear is the biggest gear you can push.

Low gear is easy but requires many revs.
High gear is harder but requires fewer revs.
Which is optimal ?

In other words, it's very rare for both groups.
I think there's a lot of confirmation bias involved here, people will now start doing the anecdote thing, and anecdotes prove nothing. We remember the ones that fit our scenario and forget or ignore the ones that don't.

If your knee is already injured, obviously you may need to adjust, but there's no way of knowing whether the gear push actually caused the original injury.
We had a guy who had blown out his knee by some non-cycling activity, and he reported that he could push a high gear more comfortably than he could spin a low one. It's a really weird joint with a lot of variation in injury.

Using a gear slightly higher than gears a spinner uses does not qualify as mashing in my book. I would expect not great difference between the two in that case, as you state the study found.
No question, knees are not standard issue. If something is causing you pain, you definitely should do something different. I just don't believe the horror stories about the guy whose knee was just fine, he continued to mash comfortably for years, and then one day his knee exploded for no other reason.

What are you doing with the gears in back?
