  • Two weeks after publishing the ONLY review seen to date of the updated Shimano R8100-P (& R9200-P) firmware 4.2.0, I'm struggling to get a resolution from Shimano Australia regarding the issues I encountered. The data presented clearly indicated there's a problem with the power meter I've purchased. Their initial reply was very generic and indicated they had not reviewed the issues in any way. Here's a breakdown of their reply and how it may or may not apply the testing I perform.

    I think Shimano's mechanical engineering ie their geometry, fits etc is good. Their materials knowledge of raw metal is good however their use of glued joints has proven to be suspect.
    On the electronics front, a lot of Di2 is Bosch derived (CAN BUS) and I think the power meters were technology that was bought from purchases so it's not Shimano from day 1. In any case their customer image has taken a battering over the past few months and this is no exception.

    • @nctrns
      @nctrns Před 8 měsíci +2

      Was it you or PT that suspected that they have problems with right side PM due to their crank design? The bonded crank and complicated geometry doesn't allow for a good strain gauge placement and proper calculations of strain.

    • @Timo-qb1gf
      @Timo-qb1gf Před 8 měsíci +2

      ​@@nctrnsI think the unsymmetrical design and manufacturing methods (glued joints) are inherently a bad match for a strain gauge based dual sided measurement. There's a reason why most other manufacturers use either a single piece cranks and/or different measurement setup like spider based ones.

My case was some software error in ROAM which I, as A person with over 20y exp in software design was super happy to help to solve (for mutual benefit) but Wahoo decided to take an "easy way" - close the ticket and pretend the problem never existed.

If the power meter is trash, I don't want to buy such a bike, and sometimes it is a shame, because the bike looks great. So, for me, they either have to fix this power meter, or companies should not sell their bikes with shimano power meter becasue they are making thier products less appealing.

    Regarding the alignment of the cranks and rings: R8100 and R7100 never did. But R9200 does. My hypothesis is it is a cost cutting, they haven't made specific molds for the lesser groupsets, so they are all "Dura-Ace". To test my hypothesis is easy, I predict a 105 or Ultegra ring would fit better to Dura-Ace crank! Unfortunately previous generations were perfect... We were expecting more for their 100th year, not less.

    I’ve just bought one of these meters because I rode on a sram axs spider which was fantastic, but decided to experience dura ace which I love.
    Problem is I had assiomas but I thought they were poor accuracy wise…
    Never had 50/50 or 49/51 like I did on my sram spider that coupled with the fact my feet were soo far apart it hurt my knees 😂 I looked for a crank set meter
    I didn’t see this video until I was getting the same 53/47 showing on the dura ace power meter.
    Please don’t let this go Shane you might make them fix it through firmware.
    Atleast my feet aren’t too far apart

    As a long time patron of Shimano North America, I'm dismayed you've had such poor customer service from Shimano Austrialia. I like to believe my blood runs "Shimano Blue"'....And hope other Shimano users feel the same way. I you're well with your right to loose a bit of faith in that particular product. More importantly, you're loosing faith in the company is much more disturbing!! STAY ON THEIR ASSES!! I hope Shimano - Down Under - finally rectifies the issue.

    It's a shame that they cannot get an accurate powermeter and try to get away with exuses. But one of their points in the reply are in fact right: As you mentioned watts are based on the SI system. So technically they should gauge their powermeters with a standard directly derived from a institute of metrology and standards (for example NIST in the US). Simply comparing to other powermeters and assuming that the others are right is not enough to make the 2% accuracy claim. Having that said: It is of course highly unplausible that all other powermeters are consistent but wrong and theirs is right. This is more an academic issue but each company has to gauge their powermeter to a metrology standard. Otherwise the errors would keep adding up.

    • @louisyoko2723

      You can calibrate Assiomas by using 1kg weights. Which should in theory make them a pretty good reference point. And if they match/are close to matching other power meters except Shimano then presumably the outlier is the issue, not the benchmark

      @@gplamajust because they aren't part of the recall doesn't mean they aren't susceptible to the same kind of issue in the long run. Shimano didn't change the design of the crank, they changed the bonding agent. And it's the design of the crank that is the culprit. Stronger bonding agent might just delay the issue not prevent it. We'll see in 10 years.

    And do the same across all powermeters in comparison?

      Static weight testing is possible with some meters, not all. It'll give a good indication if a meter is within spec for a single point of reference. Not possible with the Shimano meter that I'm aware of.

    From their perspective they can't necessarily trust your claims. Seriously, if you are taken in queue as any other customer how are they to really know you have any clue? And even if you sent in your results and methodology the first tier service isn't going to spend any time on it and just give the answers they find in their run books. But once you ask for escalation to a higher tier support you should get some response sooner than 5 business days...even if it's not a response you prefer. Don't confuse me with someone happy about it but rather understaning how tiered support works as well as how little the general user base if tech products really understand. I can only imaginf how many bizarro and brain dead questions they get.

  • @BikesBlades
    @BikesBlades Před 8 měsíci

    The only valid point they (Shimano) could make is that most of us don't have a true "Watt reference" to compare anything against - all we can do is compare different meters against each other. So yes, in the end - we generally can't analyze accuracy, because we don't have a way to produce a controlled, certified combination of torque and RPM. But it is valid to call out a meter that deviates from the values reported by other meters. Shimano is experiencing a crisis for other reasons, which is why they are dodging this issue.

    • @gplama
      @gplama  Před 8 měsíci

      I've tested/reviewed a number of SRAM/Quarq options. Same test protocol. All perform exceptionally well. One notable outlier was the Rival AXS single sided spindle needing a 6% scaling. There was a subsequent firmware that may have resolved that without the scaling.

    They probably had no idea what you were writing about and categorised your email as a complaint about power meter accuracy, so they responded as such with a standard reply and links to their website, which also explains why they didn't actually answer your specific questions.
    It even reads a bit like a response fed by AI/ChatGPT...
