Seems like the Corima 5-spoke are now available to the public in addition to a lenticular version of their C+ disc

Interesting powermeter.
It uses hamdlebar to measure your power https://powermetercity.com/product/powerpod-power-meter/ Accuracy +/- 3% which is mot bad for the price |

This is called opposing force technology. The PowerPod uses an accelerometer, a wind pressure sensor, an elevation sensor and a speed sensor – all to measure power. |

A $50 heart rate monitor could be called a "power meter" (but that would be worth it). Also, this isn't new. There was one of these a few years ago that measured air pressure and converted it into power readings. Basically, the "power meter" works by assuming that there is a base amount of air pressure present around the rider. If the pressure on the meter begins to rise because the rider is moving forward and pushing the meter into the air (making more pressure on the sensor) then the rider is exerting force to move forward. More force = more power. This works the same way that putting your hand outside of your car and feeling the air press against it to determine how fast you are traveling. It technically can work. But, there are better ways to accomplish this. |
My buddy just let me know about this:
The documentary about the US Women's Team Pursuit team for the London Olympics is now on Netflix. It's pretty good. Trailer: Info: Netflix - instantwatcher - Personal Gold: An Underdog Story |
I found some of the data analytics stuff to be dubious (it's what I do for a living).
There is a scene where the data scientists presents a chart that looks like this: (not the actual chart from the film) http://mkweb.bcgsc.ca/tableviewer/sa...s-table-04.png It looked very aesthetically pleasing while looking complex and "science-y"...but it communicated little or no information. It was as useful as this stuff is useful to programmers: https://ruangpelangi.files.wordpress...e_emulator.jpg I think the real breakthrough for them happened not from the data science/analytics but from listening to the athletes. (at least, that's how the film set it up). As well as training them differently, even though they are participating in a team event. The human body is probably the most sophisticated instrument on earth. And in the case of an athlete, the "machine" and the "instrument" that is measuring the performance of the machine are the same thing. The key is to train the athlete to listen to their body over the years as they are training their body and skills. This is obviously easier said than done, especially for beginner and intermediate athletes. But, a keen, veteran athlete is a better judge of what's going on with their system than a power meter, heart rate monitor, blood glucose meter, etc... Your brain is aware of EV-ERY-THING that's happening with your machine...24/7, 7-days a week. Maybe long-term coaching should focus on this aspect. Most coaching engagements last a season or less. But, parent-coachs and those who are charged with developing athletes over the course of years may benefit from such. I'm sure they are doing something like this, but I haven't heard much on the subject. Most of the chatter is about a new ______-O-Meter. The Borg Rating of Perceived Exertion (RPE) scale touched on this, but has since fallen out of favor due to meters becoming popular (and profitable). |
It's a watchable documentary, but it definitely injects some infomercials, and ramps up the drama - building stories that weren't really there.
Reading your comment, Carleton, I was reminded of a conversation I had earlier today with newer racer who's thinking about getting a coach. We were talking about what to look for in a coach and I realized that the good ones that I know don't apply 'the rules of training' to their athletes - rather, they now how to apply all of the variables. All of the limitations and grains of salt - they know when to apply THOSE. Anyone can write a plan - and hell, most athletes, just following one for the first time, will get faster. But knowing what to do when things go wrong - when somebody is tired, stressed out, coming back from injury, not getting the results they want - well that's where the skill comes in. |

Interresting. I thought, "pffft...they probably have a rider weight limit of 130lbs or something like that." Then I saw this:

Thanks the decorative carbon ones are nice but I prefer the stealth look lol. Nah I'm an Orthotist/prosthetist so I know how to work with carbon, measure and manufacture shoes, insoles etc....not a bad skill set to have when you have terrible feet...I'm thinking about maybe offering it to the public it would be nice to get feedback from other people on how they feel/perform

I found this description of the Raleigh frameset ridden by four time world sprint champion Reg Harris.
Raleigh track frames for Reg Harris (and others) Interesting to read about the frame's stiffness - back then metal fabrication was not up to todays practices (note the narrowed chain stay). |
I watched this and found it painful to make it all the way through. It seemed like an ad for a lot of training software to me. Talking about how all the data that was helping them. In the end the two breakthroughs they found I saw almost instantly.
1.The sprinter didnt know how to transition to the back without letting too big of a gap and that caused her to get tired quicker. 2. The sprinter was a little fat and this caused her to go too hard on the road rides in the mountains to keep up with the others, so she didnt get proper recovery. Tried to make the story more interesting by acting like they needed all this data to figure those two things out.
