Old Guy.. strength does not equal effort.. strength equals how much actual force/torque needs to be applied to the pedals to move the bike forward.. being able to put 50lbs of force per leg is all that is required to make you the strongest cyclist in the world.. cycling is an incredibly difficult, painful sport, but 50lbs per leg is peanuts when compared to the strength requirement of many other sports.. 50lbs of force it the amount of force that can be put out by a pre-pubescent little girl. strength is not the limiter for cycling obviously.. what is is your bodies ability to perform many SMALL torques in quick succession for hours and hours.. be able to get oxygen and nutrient to the muscles and the rate that an individual can metabolize those and get muscles to move.. cycling is not about strength at all (the magnitude of the force)..
i.e. cycling is about power.. not torque.. unless you're a match sprinter on the track then you better hit the weight room..
you have a power meter.. how much torque do you topically apply to the pedals?
Typically: 8nm seems reasonable on my trainer. 35nm seems reasonable on hills.
It is difficult to separate torque (strength) from power, but I will do it for you. Put you bike in the lowest gear you have and ride up a 35% grade. There is one is San Francisco. At some point your bike will come to a halt and you will lack the strength to move the pedals forward. (Power is force times a distance and here the distance is 0 so the power is 0.)
At the other end of the spectrum: Learn to use a very high cadence. Now go out for a ride at your very high cadence in your highest gear. Get a higher gear if necessary but at some point you will reach the point where you lack the torque to go any faster. (F=Ma leads to something like torque*cadence - drag >0 to accelerate.)
Certainly power is one measure of ability, but I have now shown you that strength is also a measure.

Further the cadence of 90 that some people feel is optimal is due to the fact that the torque (strength) is reasonable for the power output. If power was the sole concern, cadence would rise as power rose.

I find it difficult to understand why a bicyclist who does thousands of repeats would consider 1 repeat or even 10 repeats (common for weight lifters) a proper measure of strength. I guess it is the same mind set that allows a bicyclist to believe that FTP (a 1 hour measure) is a proper measure for a 5-6 hour event.
