Trek BB95 Campagnolo crank arms and chain rings. New. More testing is needed, though, I suppose it does highlight the rare scenario where even if the accuracy is perfect, that a left-only power meter still has obvious limitations. I cant seems to find any. Based on past SRAM compat Im gonna guessno go. BR-R9270, BR-R8170, BR-R7170), the previous generation Ultegra, DA, 105, GRX STIs are compatible with new calipers (but new STIs arent compatible with the old calipers).

So here is the most up to date list of products I like and fit the bill for me and my training needs best! I think for this, the argument against single-sided is pretty obvious, ignoring the other potential variances in any PM being discussed above. Calibration offset is all over the place as well and will jump up and down significantly during single workout sessions. Finally, the Flattop chain will not drop down fully into the tooth valleys in Shimano front chainrings. Our wages is not increasing that much. What I am really curious about is if you know if power measurement is in the spindle or on the arm itself and the wires then go internal to the electronics. The guy that invented the Virtual Elevation technique, RChung, recently posted on ST that the single-sided power files that are sent to him have proven to be too noisy to use the technique. The spindle is not long enough for 92mm mtb. I think in this Zwift cycling era too much credence is given to power, W/kg or FTP as an absolute measure of everything. Sram Red Axs Quarq Power Meter Crankset, Speed: 12, Spindle - Target Come on man, 125 EUR for a cassette, That said, why on earth on this bike Im seeing a massive left/right power difference is interesting. Watch to get professional road cyclist Joe Dombrowskis view. compatibility with 11 speed. Again, I have not tried it, but based on that response, it would seem that, first of all, a non-AXS would drag on the adjacent larger cog. Im a bit nervous about the power discrepancies reported but I was thinking I could hook up my present PM (which I trust) to this and then use Rays file comparison tool. I can literally comb through all my data and find this for virtually every power meter. It is a 2x chainring but it uses a 1-piece integrated power meter and chainring design. Wanna create comparison chart graphs just like I do for GPS, heart rate, power meters and more? Most certainly it wasnt 6% (so I would need the so at least 10% lower readings). A 500 Series OCLV Carbon frame and fork with Kammtail Virtual Foil tubes that cut through the wind and a road-smoothing IsoSpeed decoupler. Though, from an end-consumer standpoint, swapping out a spindle and a crank arm (and first detaching the drive-side crankset) is hardly 1-minute type work. Greetings from Italy. No backward Lets say your ftp is 280w-300w (realistic for normal people below 50s year old).

Protocols: ANT+ & Bluetooth Smart Video: link to youtube.com. Ultimately, itll be interesting to see where this goes. Seems like its just a cheap system that produces numbers that have at least some correlation to the pedal force. Your power meter feels all of the forces on the crank/pedals, not just the forces that your legs produce. . At this price, if compatible with regular Rival, Id buy one today. My best guess here is that this bike is too small for me (it is, considerably), and thus, my pedal stroke is substantially different. After several rides with the Rival PM I switched the XTR pedals for a pair of (left sided) Assioma Uno pedals (which are somewhat in line with my Assioma Duos, 4iiii and Kickr power numbers) and did some test rides on several different days and did a zero calibration for each device before every ride. Release Notes I did get at least two firmware updates in ne meantime but shitty weather doesnt get my girlfriend in her bike to test .

The Trek-Segafredo team uses them on every training ride, any time of dayand theyve found that these lights truly make a difference. While its cools to see the Vector pedal stuff and the individual leg power, its really not all that useful, but I am not a racer anymore. If others have similar experience, Im curious if total power output increases after addressing imbalances. And since Im in the lucky position of knowing with 2-4 power meters per ride which one is having a bad day, then I can discard that unit for that ride. I have built an extensive list of my most frequently asked questions. Hub Spacing Compatibility. Then, I come here and write about my adventures.

My question: although the new calipers are compatible with the previous generation STIs, will one actually get the enhanced pad clearance functionality with this combination? And the imbalance varies depending on power level, among other things. Your stuff is always awesome! I aim to leave no stone unturned. I am not even considering people who like to measure their sprint power (by the way most strava segments are short and are about sprinting or efforts at vo2max ). This means the power meter spider and chainrings are bonded together, which makes the power meter lightweight and stiff. Very interested in this as my husband claims spindle is the best place for torque measurement and inline 6 engines are the best for balance. And that for most people, even with slight shifting leg imbalances, I dont think its as critical an issue. And yup, Robert and I have talked at length about this topic before.
