• I think it could work as a garmin/smartphone add-on (ie. 1/6 of the price) but yeah it's most of the price of a real powermeter.

  • It measures the resultant air speed against you+bike (so wont work as an app, unless you Iphone has a built in air speed detector)

    It measures the rate of Climb of you+bike.

    It then uses thes together With frontal area, and weight information. To calculate how much power you must be putting out.

    Basically its no better than a PowerCal. As in it'll give you nice TSS data to add to Your training logs. But realtime data will be unreliable. What would annoy me. Is that for a given weight, speed, and gradient it will give a constant reading. So using Your PM to achieve max speed with minimum effort is out.

  • I imagine the Strava Power data is basically this minus realtime windspeed data (so some constant instead).

    Would be cool if you could integrate weather info over a gradient map. together With rider inputed weight and frontal area values. To give a rough Power curve post ride. It would only be cool if it was near free though.

  • You can get physical smartphone add-ons though (ant+ receivers, for example)...

    I Guess a add on air speed sensor neednt be mad pricey.

  • add on air speed sensor.

  • ^Mine was an absolute car crash; got a part refund off Wiggle when I complained to them and Paligap. They are machine built and my Pro/Velocity A23 from 2012 wasn't even dished correctly and spoke tension was completely random.

    Finally got round to checking these (CycloOps Campag wheelset), or at least the rear wheel. Dish is good to within 0.15mm, and the spoke tension is even on the drive side (24 - 24.5 on the Park TM1). Spoke tension on the NDS is a bit more variable, but they're true (+/- 0.1mm except for the hop at the joint) and round, so I'm optimistic they'll stay true. Hoping to use the rear wheel for the first time tomorrow, if I get back from Cardiff in time.

  • Actually ended up fitting both wheels. They're obviously doing something right, as I set a new PB-on-my-winter-training-bike for my standard 20 mile training loop*. It might just be the psychological motivation of having accurate power readings spurring me on, but either way I'm not complaining.

    • Actually 19.8 miles. Pancake flat but with road surfaces which in places make the Paris-Roubaix cobbles look smooth. Goes through a place called Pymoor. Hmmm, pie...
  • Play developing in a powertap with correctly installed end caps, bearing death?

  • You sure they're done up tight? How much play? I've got spare bearings you can have. Just steel, none of this ceramic bollocks.

  • follow your Chronic Training Load (CTL) in your Performance Management Chart (PMC). The PMC is a Premium feature within TrainingPeaks® and is also available in TrainingPeaks WKO+

    So the most important metric according to a salesman is the one he's trying to sell you? I'm convinced.

  • The PMC is about 2 mins work in Excel. Doing it in Excel also allows you to easily project forward which is a ball ache in WKO

  • Also available in free software like Golden Cheetah.

  • You sure they're done up tight? How much play? I've got spare bearings you can have. Just steel, none of this ceramic bollocks.

    The new end caps just pop on and off so tightening/adjustment not possible, ordered some SKF off Tweeks who are cheaper than any of the usual bearing mail order spots

    All the cool kids use WKO+. Go on.. first one's free..

    Ah, yeah, the Kinesis has the old style that I'm used to having to tighten now and then.

  • Premium Training peaks is pretty nice. I jumped on a special offer and paid for the year so its pretty cheap that way.

    I'm naturally a overtrainer. Quantity not quality type. A problem exagerated by my amount training time being out of my control. My PMC nearly always looks horrible.

    For a MAMIL like me the free version is probably fine TBH. I was mainly motivated by buyers guilt re: the PM purchase. Figured I should maximise my use of the data.

    Beat me to it. I would be doing some more testing/bookings if it wasn't bloody raining and gusting at 40mph all the time.

    I've actually got one of the wireless iBike iAeros (that give you real time CdA when paired with an ANT+ power meter), except that it doesn't. Not a patch on the AeroStick

    Never considered you could combine both. Very clever.

    I have an dissusion along these lines With my riding bud. Since installing some vectors hes obbsessed With his max Power figures. I was arguing that I'd much rather be able to ride as fast or even faster than I am. But using less Power.

    Pretty sure I averaged 180w for a recent 215km ride. Nice and low, as was my HR.

    Guess it Depends on what you're trying to achieve.

  • If you want to go faster you might as well work on improving your power as well as your aerodynamics!

    Chasing peak power is fun but doesn't always result in you going faster during a road sprint, you end up doing efforts with >50kph entry speeds at the bottom of hills with a perfect gear to get MegaWattage rather than replicating what might happen in a race. I've hit ~1600w with the above tactic in training but only 1350-1400w for track/road sprints. Personally I was best when able to do 1100w for 30sec and 1450w peak than when I could peak at 1600w.

    Xav

  • FWIW. I'm trying to og further most of all. Hence the interest in maintaining low effort, while still moving at a respectable pace.

    Last time I went for a 5sec max I nearly crashed into the back of a ford fiesta. Turns out a cyclist had pulled infront of it. Bloody cyclists.

  • Tricky question for the Power lovers.

    What would be the resale value of a set of Vectors, fully boxed, pretty spotless, With less than 2000km on the clock?

    A friends not getting on With the pedals, and is considering swapping to Stages.

    I'd love them myself. For use on the fixed gear, which I actually do some hard riding on. But that simply aint happening.

  • dibs your P2M ; )

  • They probably haven't dropped that much in value yet, tbh.
    You can 'get*' them new for about £895, so £6-700?

    • Aussie Ebay.
