No training scheduled for last night, so I took the time to check it more thoroughly. It turns out that the rear wheel can be pushed from brake pad to brake pad with no resistance, and I keep the rear brake pretty wide. The skewer was tight.

    Dead bearings? Other stuff to check? The hub has 10k+ miles on it.

    Threshold intervals again next week...by HR.
    If it's cup and cone bearings, you need to adjust the preload. Your bearings might be toast from being improperly adjusted too, but get the preload right first, and if it's noisy or whatever then replace the bearings.

    If it's cartridge bearings, you need new bearings. I'd just take that to a shop, not really worth doing it yourself imo.
    Do you think we're gonna make it? / I don't know unless we try \ you could sit here scared to move / or we could take them by surprise

    thanks fudgy and shovel,

    I got the magnet way closer to the crankarm and have had zero drops since then. I analyzed it in WKO+ and did see cadence drops.

    Here is the current setup, 3 strong batteries stacked, held on with electrical tape. Works like a charm(knocks on wood)

    -Cat-3-o-meter: TBD :/

    get some of the permanent putty. I had a temporary tape setup that I sort of forgot about, sort of figured was working so why change it. Then one day the magnet fell, latched onto the chain, went back and jammed into the rear derailleur, ripping it off the frame and having that whole mess go into the rear wheel.

    skidded to a stop, luckily, but was still an expensive day with the hanger, the chain, the derailleur, and a wheel rebuild.

    I jury rigged a piece of plastic to position the magnet. Mounted that to the bb and then attached the magnet to that.

    the putty fell off my other bike I dont trust that solution so much myself bro.
    but thanks for the heads up!

    I'm so glad I never had to deal with any of that crap on my bikes. Luckily both of my bikes the magnet ring fits and works with. So easy BB cup off, ring on, BB cup on install!

    (Then again, my bikes are crap compared to most of you).

    It's actually pretty small. It's whatever size fit through the hole. Optical illusion.

    So I went ahead and registered and pooled all of my data into cyclinganalytics over the weekend. I am not keen on a pay per month/yr site for my data but it is cheaper than TP and I REALLY like it. Right now, I am also using GC and strava but will start mostly using cyclinganalytics as I give it a few more weeks of trail.

    I do miss some of the plots and customization of GC(but then again I will be running GC too). So far, the calculations seem comparable between GC and CA but I need to dig a bit deeper into the math.
    Editing the ride is a bit easier in GC and you notice a bit of a change when you have a ride where say you are idle for 20 minutes waiting on someone vs a ride where you are constantly riding. I plan to edit the rides in CA and see if i still get variation in trimp and power etc. which i suspect wont be an issue as all other rides are exactly the same data wise.

    interface is just phenomenal and it will be an easy software for me to pick up as a new power user. Initial plan is to use it for a year and as I get more familiar with analysis migrate to GC.

    edit: their calander is pretty epic too

    On the topic of decoupling:

    I really enjoy the decoupling analysis but not sure if I am missing a few things. My basic premise of decoupling is that it is a relationship between power and heartrate. If power parallels hearrate than you are in good shape and as power drifts further and further apart than it signifies decoupling and being well less "in shape". Something like say 10% decoupling.

    My data doesn't seem to correlate though:
    examples: commute ride-avg heart rate was 120bpm so easily zone1-2 and my avg power was also zone2 and it was an easy two hour ride but my decoupling was 19.4%. That ride was in the evening and I had pretty much the same ride that morning with a decoupling of less than 1%(avg heart rate was 114bpm).

    I had a harder ride sunday @ 3hrs heartrate avg was @140bpm but I had several instances where I pushed it(group ride) and my decoupling was 5%.
    followed by 2.5hrs the next day heartrate @118 decoupling 9%

    Power outputs for each ride would avg out to be zone2ish as well

    Just doesn't add up unless the software I am using is bogus.

    Last few weeks GC has been crashing for me. It has something to do with the latest Edge firmware and GC not being able to read the files.

    it has to be a steady state or a quasi steady state ride. commute = too much stop and go, ditto for group rides.

    this is why i don't like the metric that much. i can go do a long steady ride with 2% decoupling even when i'm out of shape, and it means absolutely nothing... Alternatively, i could do a long steady ride with a 3% decoupling when i'm strong.

    so I just discovered that you can use GC to find your best XX intervals of YY duration.

    Wish I'd found that earlier.

    Anyone know how to export power data from CycleOps Power Agent? I started with power agent when I got my powertap because its easy to use, but I've had GC this whole time, just never used it. I want to try it if I can get the data moved over. I've been downloading the data directly from my Joule to power agent.
