comment What is neuromuscular endurance in the world of bicycling?
If you're interested in this question because of its relationship to cadence, perhaps you will want to read this: bicycles.stackexchange.com/questions/12518/…

comment Why am I not seeing improvement in my bike split time?
There isn't enough information in your question to provide a good answer. How did you place on the various legs this year compared to last year? Is the bike leg mostly flat or quite hilly? Except for the aerobars did you use the same bike, same tires/tubes, and same clothing/helmet? Going into T2, where you about as tired both years, or did you feel you had more in the tank starting the run? Overall time improved by 36 minutes, most of which was in running. Did better pacing on the bike improve the run? All of these can affect the SBR splits.

comment Accurately replicating the resistance felt whilst riding via a resistance fan diy turbo trainer
@DanielRHicks, Alex is familiar with the inertial load. Here is his home-built resistance trainer and its flywheel. User95786, here are some estimates of the drag parameters (the "virtual" CdA and Crr) for the Lemond Revolution. Perhaps that will help you in building your own.

In general, constant power output gives you the best times when the conditions (slope and wind, mostly) are constant. So pacing is an obvious place to look, but that depends on having a power meter that is accurate (not just consistent) over a wide range of pedal force and pedal speed. So it might be important to check your PM before relying on it to pace or to isolate gearing choices.

And, btw, there is a way to calculate the gear ratios you used -- but not necessarily the gear ratios you should have used. That's an entirely different question.

I'm sorta surprised you could hit 500 watts near the end of this TT since you did the first 3 minutes at ~370ish. So, you may be able to improve your time with better pacing. However, you'll also want to be sure your PM is working properly. From your other question it appears this is from a Stages, right?

comment What's the lowest safe cadence on a climb?
@DanielRHicks: you're right that max pedal force isn't constant across all cyclists but the classic dataset collected by Kautz (isbweb.org/data/kautz, or anonymous.coward.free.fr/rbr/kautz.png) shows that max pedal force is roughly twice avg. pedal force (in the Kautz data, max is 1.85x avg), whence the rule of thumb cited above. This has been verified by more recent pedal-based power meters like the Garmin Vector.

comment What's the lowest safe cadence on a climb?
It's easy to calculate the maximum force at the pedal but it's hard to calculate the "safe" force at the knee since that depends on your knee. A reasonable rule of thumb is that max pedal force is around 12*watts/rpm, and that applies whether riding on the flat, gentle climbs, or brutal climbs. Of course, on brutal climbs you'll need the right gearing to keep your power down -- with your current gearing up a 15% slope your power at 90 rpm wouldn't be 225 watts.

comment What's the lowest safe cadence on a climb?
BTW, from the information given in your question, it appears your max pedal force will be around three-quarters of your body mass (i.e., less than your body mass).

Does the section labeled "Cadence and knee strain" in this bicycles.stackexchange answer address your question? bicycles.stackexchange.com/questions/12518/…
