There have been designs, but cyclists tend to be picky about increases in weight or losses in efficiency. Bicycles do not have the problems of large spinning masses or rough clutching at low speed, and we seem to do OK with discrete steps in the gear ratio.

The NuVinci® N360 is a continuous variable transmission that is roller based. It is marketed and used mainly on hybrid and low maintenance city bikes. They must have had some market success as they have been around since 2006. I recall seeing them at Interbike around that time. More info in the internal structure

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 ...

Your current bike has decent wheels and reasonable components. If they have been maintained well I don't think you'll see much difference there other than 10spd gearing. The big change to a new bike in that price range will be the frame. It is much easier now to get a frame that actually fits your riding style, I see you have an adjustable angle stem. ...

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 ...

TL; DR: There is going to be a lot of difference. A 1500 Euro bike today would probably be comparable to a 6-7000 Euro bike from 10 years ago. Elaboration: There are going to be quite a few improvements in the bike due to technology advances and research and development. Some of the base models will not be radically different from your frame, although even ...

Lighting control isn't exactly a good idea since you have 2 lights (front and rear) on a bicycle typically. Most cycling sensors (cadence, speed, heartrate, etc.) either speak ANT+ or Bluetooth these days, so if you want to read sensors, you just need to know how to speak ANT+ or Bluetooth in your chosen language. You can also add a GPS module and other ...

Try re-pairing the 510 with the speed/cadence sensor. It seems like it's not connected and the speed data is coming from the GPS rather than the sensor. As suggested by others, the alignment of the speed/cadence sensor is important, but it must be close since you seem to get a little cadence data before it drops out. Perhaps it's too close and your crank ...

I also have an Edge 510 (since ~3 months) with the same sensor, but I have not experienced this. I have recently updated to the latest firmware, which often solves similar issues with power readings. Since you were riding at quite low temperatures, the capacity of the battery does decrease, but since the speed reading is fine I would not suspect the battery ...

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 ...
