snip My son asked me the same question, and I kind of relented -- agreeing to buy his Ultegra crank arm cheap if he upgrades to a Dura Ace double sided -- which he may do when he builds a new road racing bike (he sold-off his old Tarmac as part of a down-sizing and spends more time mountain biking now). Like I said, knowing my power is not a big deal for me. A few years ago I was contracting for a small company and we were invited to present at a very large bicycle manufacturer. We had several sensor-based products we could do for them. A much-improved assometer for seat fitting, tire pressure sensing (not for tubeless though), and spindle-based power-meter that did not use strain-gauges. The assometer design was too expensive for them to consider, it would have cost about $100 to build and would have to sell for about $200 to shops, but it might have helped sell more high-priced seats. The spindle-based power meter measured both right and left power. It would have been pretty cheap to manufacture, adding about $25 to the BOM of a new bicycle. But the thought was that only a very, very few cyclists care about power meters and to build a $25 extra expense into every bicycle when it's being manufactured would not be practical. One company did offer a spindle-based power meter for a while, for about $600 https://www.bikeradar.com/news/easton-race-face-launch-spindle-based-cinch-power-meter/. There is still some stock available. The replacement product goes onto the crank spider. Also around $600. I think that pedal-based power-meters are the most likely to become more of a mass-market item since they can be manufactured cheaply and are easy to install. Right now they are costly, but as soon as some Chinese company starts making them the price will fall. |

I wouldn't complain if it was $25. But we're talking $500 and up. And that is a lot of money for almost no return. That logic applies as well to almost every "you gotta have it!" bit of bike technology since index shifting. The industry is chasing after ever diminishing improvements and touting them as necessary. Since index, the only real game changer for anyone except racers has been e-bikes. And that's because they're a step away from being a bicycle. -- - Frank Krygowski |

That is true Frank, but do you recommend a person who has been out of work for a year buy a $10,000 bike? Though I suppose that I shouldn't ask you that since you don't think that anyone needs more than a $25 touring bike. People want what they want and indeed some of it is pure foolishness. After 10 years of covering the ground I did 40 years before my concussion has brought me back perhaps closer to your point of view than that of Velonews. I am now going back to "normal" bikes that cost me about $1,500. Perhaps that is higher than you would spend but it isn't the sort of bike you wouldn't feel perfectly comfortable riding. |

Or as I also say, "to chronicle our decline." And I knew that *before* I bought two power meters (two bikes). I just wanted to play with the data - which is fascinating for a data junkie like me, with lots of surprises - but "how strong am I (not)" is not one of them. And yes, the iQ2 saga has been interesting to watch (dcrainmaker.com has documented a lot of it). I only followed b/c that was the only game (nearly) in town for mtb pedals before Garmin's recent release. Mark J. |

Also for non racers there are many improvements and E bikes is certainly a game changer. It's a 'plaque' around here. Now also 'old' people can go fast or less fast without getting tired or sweating.
