    I’ve been using a single sided Stages because the wait time for 12sp Shimano ultegra was over 12 months when I bought my bike. I’m so happy with it (although I realize it’s different than dual)! Much better than my Rally pedals that seem to “reset” all the time, inflate my power data, etc.

      just curious, for a rental, do you use head unit gps for speed or do you also slap on a speed sensor? just switched to assiomas myself but have cadence and speed sensors for my garmin 1030+. cadence can be had from the pedals, but definitively not speed.

    It looks good, its not over the top expensive, works as a crankset and works as a power meter. So how come Shimano can't manage that? This is the one to buy by the looks of it if you're after a dual sided crank based power meter. Great review as usual and nice and informative. I'm still sticking with my Assioma duos though 😀

    Hi Shane, I have had big reliability problems with 3 R8100 right side units.
    I bought two Stages LR Ultegra R8100 power meters (one for each bike) because I wanted an accurate dual sided Shimano meter.
    The left units work perfectly, but I had to have both the right units replaced under warranty for strain gauge failures and one of the warranty replacements failed this morning.
    The Stages calibration value is supposed to be 890 +/- 50. The left units always calibrate consistently but after less than a month in each case, the right units have started calibrating anywhere between 390 and 1046. Obviously, this leads to very inaccurate data. I had to go back to running them as left side only power meters.
    Its very disappointing, especially when they worked well initially. It might be worth noting this so people don't go out and purchase these.
    Thanks,
    Conor.

    My Giant TCR 2020 came with Di2 and Giant Power Pro. Great value. No idea on accuracy, but as I had nothing to compare it to directly it suited my very amateur needs. But now one side isn't showing power as my wattage is ~50% of what it was. Charged, heaps of calibrations, no joy. Now I'm faced with a choice of what to do. Roughly $2k for Garmin pedals, $1400 for this Stages Ultegra unit (which includes a full crankset - what do I do with the old one, seems a waste), or the Shimano unit at who knows how much. Given the bike itself was $6k new, it's a lot of money to replace one little electronic component.

    This is very good to see, given I've just got my hands on one! 😁 One thing I found though was the 'Stages Cycling' app (Android) only reports power from one side in the 'Ride' mode, so reported power is around half, with L/R ratio at 100:0 (or vice-versa, can't remember). Data tab shows the data from each, and no problems on a real head unit (overall indoor test ride figures via Bolt were within 1-2% of my KICKR on Zwift, and L/R balance showing ~52/48) so 🤷

      @Dragos02 Год назад

      The only pedals that don't require ridiculous shoes and work great at the same time are XTR 910. And Assiomas does change the q factor which is a big deal on 100miles ride.
      So why use Assiomas when you have Stages - as Lama says: when you replace a product you have to be at least as good as that one

    Stages are my goto for crankset based powermeters. The solution though I'm not sure of. Having sensors in a relatively exposed position is concerning. If they're secure and well shielded then ok. Otherwise it's more of a hack workaround to the inherent issues with the 4arm spiders.

    I find it odd that pedal meters are no longer a "price point" favorite relative to a crank solution. It used to be the "look cleat" + meter (assioma/garmin) just flat out beat anything crank based cost wise thus it was worth the limitation of being look only. At this point...I think I would much rather be on crank based and have a choice to look at other cleat styles especially with "gravel" being more popular.
    And LOL on the triathlete comment...I resemble that remark.

    Your review was a tiny bit lacking. Unless they somehow redid the design, you will not be able to use aftermarket chainrings such as absolute black, as the pod will interfere. This caused me to get left side only for the R8000 set I have now.

    Would you still recommend the Direto XR these days? I'm right about to get a trainer and though I'd really love the Elite Justo, Direto XR is quite a bit cheaper, both these trainers seem to me as better value than let's say a Wahoo Kickr v6 or Tacx Neo 2T from your reviews.

      The Direto XR works well for me. If you can test ride prior to purchase I’d recommend it.

    Why would you want to buy anything except a quarq dfour when they are super reliable and much cheaper?

      Having to use SRAM cranks and another BB type. The DFour needs updating to better (cosmetically) match the 8100/9200 rings.

      @@gplama fair point, it is not yet 100% 12 speed compatible. Changing to GXP/DUB (depending on BB) is worth it in my opinion though. I decided to stiick with 11 speed di2 for my new bike, the prices of recent groupsets are insane.

    Stages make great power meters but it should be stated they have no support. Support tickets will go months without being answered. Found this out the hard way. Now I have a non functional SB20 and a power meter with no cadence and no help from them.
