While not disagreeing with the first answer above I think there are a few more complexities that haven't been addressed. Changes in bike technology are not linear but rather generational. Component improvements don't happen each year but rather every 3-4 years. Aside from pro and sponsored riders most riders would not see any value in replacing a bike for ...

The raw pedal force or torque data are difficult to work with but you can extract some information from them. First, note that Stages mounts the strain gages (or gauges) permanently to the crank, so the crank length is constant and they know what it is; that means that there is a one-to-one relationship between the kgf and torque columns. In this case, it ...

Pretty broad but it has not been shut down Components High end road bikes are marketed to racers. UCI and other racing organizations have rules on what can and cannot be on a bike. Biggest changes will come from rule changes. UCI allows electronic gears. There is currently a minimum weight for road races and pro level bikes get under this limit so there ...

I like @DWGKNZ's answer, especially where he's saying about things tending to move forward in big bangs, rather than some gradual linear progression. You will of course find small-scale enhancements year-on-year, but these would not be big enough to convince you to get a new bike, say. I just wanted to add something about hydraulic brakes. But also I'd say ...

Negative force/torque power !+ actively resisting the pedal. Thus, no conclusions about pedaling "style" (even for the left leg, which is all that Stages measures) can be drawn from data such as these.

I agree both are measuring torque/force. That is the ratio you would get with 170 mm cranks. 1 kgf = 9.80665 newtons. 7.3 * 9.80665 * 170 / 1000 = 12.2. But without pedal angle I agree you cannot calculate work or power (wattage). And this appears to be just one pedal. stagespower-tech-specs P=2∗((Fave∗9.8∗L)∗(R∗.1047)) From there, the rest ...
