sram force axs power meter compatibility
Of course, with a 50w split, one could probably do a Virtual Elevation pass on this and get a good ballpark estimate which one is right. Uses a CR2032 battery that lasts for 200 riding hours and changes without tools. This Force power meter features a spindle-based design, meaning the power meter sensors are neatly and securely packaged within the DUB spindle for a clean integration, minimum weight and maximum durability. And perhaps more importantly, the ability for a consumer to quickly and easily just insert a power meter into their bike in a minute or so all for $250. (To be clear, the bike is perfectly fine and nice, just perhaps not entirely my size which, Im 100% used to. No problem, here's the platform I use - you can too! Same slight lag on Quarq, but nothing to focus on at the moment: I got on a conference call with SRAM/Quarq to discuss, and ultimately none of us can know which unit was incorrect on the first ride. What Im wondering though is if it is compatible with non-AXS. Its as simple as that. 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 ). zero offsets??? I can upgrade my Rival to a PM or I can shed a ton of weight and go with a non-PM crank. Can anyone else confirm if the update has corrected the in accuracies? While in SRAMs case its RED, Force, and Rival. At this price, if compatible with regular Rival, Id buy one today. If I shine a flashlight down there I can see the connector. For all the power meters you bought so far that are 11 speed compatible: just throw them in the land fill. Trek engineers designed a decoupler that allows the seat tube to rotate independently from the top-tube-to-seatstay junction, increasing vertical compliance to twice that of our nearest competitor, without compromising pedaling efficiency. And since left is doubled, in theory those matched (this set is against the Garmin Rally pedal set): Thats both good and bad for Rival. There are several power meters that will work a SRAM Force crankset. Shimano Dura-Ace vs SRAM Red AXS vs Campagnolo Super Record - BikeRadar Price is 270 in the Uk. Does anyone know if Id be able to temporarily set this up with a DUB PM on the drive side to test accuracy? . I have built an extensive list of my most frequently asked questions. This is bloody insane. Battery Duration: 400 hours Want to compare the features of each product, down to the nitty-gritty? However, there are different versions of Force cranksets, so please see our notes below regarding compatibility with each version. And of course they do they all do. Ill try that next week. Yet, for all but the trainer ride (which, isnt explainable), my leg balance on this bike is way askew. My Stages crank arm based PM on my road bike is pretty accurate, as is my Tacx Neo Trainer so when I got the gravel bike, I had 4iiii install a PM on my left 165mm crank arm. 500 Series OCLV achieves a superb balance of light weight, strength, and stiffness that's perfectly suited to the sophisticated frame technologies that distinguish Trek frames. One thing I can say, though, is Im disappointed that MagicZero doesnt seem to be supported kind of annoying to have to go into the app and zero before every ride. Most certainly it wasnt 6% (so I would need the so at least 10% lower readings). I have a B-bike that doesnt have a power meter, and if I could throw something cheap on it that could get me in the ballpark, thats all I want. New. No problem, the product comparison data is constantly updated with new products and new features added to old products! I have a SRAM Force crankset. What power meter can I use? Seems like its just a cheap system that produces numbers that have at least some correlation to the pedal force. Thanks Tom appreciate it (and, appreciate being a DCR Supporter)! Quick view. So now, only Campa and Shimano are offering cross compatibility in their 12 speed range. Ive talked a lot about variations throughout a ride especially, and at differing power levels. I dont have any deeper experience on the battery side, since they took it back shortly thereafter. See the compatibility map on the service portion of the SRAM website.. Learn more about everything Trek is doing to make the cycling space safer, more inclusive, plus a whole lot more fun. Dont hesitate and get it unless you need dual power measurement. I cant seems to find any. Your stuff is always awesome! Yes, a single sided power meter is sufficient for most people to track progress. See more I agree, replacement parts are silly expensive (as one who just purchased a 12sp cassette for this bike to put this on a trainer properly), but I dont think one can imply this is for high end ridres only. Theres a thread on Slowtwitch with several posters documenting poor data from left-only meters due to leg imbalances. Regardless of compatibility, Shimano recommends using the same generation brake lever and caliper for the best available braking performance.. They are reliable, accurate, easy to install and can be moved between bikes. That battery pod then plugs in to the far side (drive-side) of the spindle internally. My question is if theyre all essentially left crank-arm based PMs anyways, would I be better off with a Ralley 100 or 200 (which I can buy now for an arm or a leg) or wait for the Rival PM AXS Upgrade kit. So Ill place my girlfriend on my Kickr Core and test at various Powers (50-200?) Then, I come here and write about my adventures. New Firmware Available (Version 1.1.16) This is at odds with their 10 years long practice of reusability and cross compatibility. Also compatible with 12-speed SRAM Eagle, Campagnolo, SRAM AXS and KMC (not compatible with Shimano 12-speed chains) . Upgrade compatible with RED and Force eTap AXS 1x . BB Compatibility: All SRAM Road DUB BBs, except Ai, All SRAM Road WIDE DUB BBs, except Ai: Speeds: 12: Chainring material: No rings: Bolt . Thats a 3%. To work properly, this page requires JavaScript to be enabled or to use the most recent versions of Google Chrome, Safari, or Firefox. Finding consistency across three different power meters and bikes has been challenging. We're always here to help you. but now with snow and such I regularly fail to properly clip in due to snow and dirt. $430.25. Using a power meter, that actually deserves the definition. Lastly, have you or anyone you are aware of actually tried it? It fits both the DUB and GXP versions. Unlike past Quarq spider-based systems, this spindle-based system is more akin in functionality to a left-only single-sided power meter. If thats true, thats enough difference to ensure that the Shimano 12-speed derailleur wont line up over every cog across the AXS cassette. In addition, the Rival AXS power meter can be paired up to the SRAM AXS app, where you can check settings and save it to your virtual bike. Zero offset supported: Yes Battery type: AAA Lithium Battery Duration: 400 hours Waterproofing: IPX7 (thus 30-minutes at 1-meter deep) Pricing: $249 for upgrade kit, or $349 for complete crankset including chainrings There are still a few of these out there new from retailers and one could probably find a good used one on Ebay.

Then of course theres dual-sided power meters, like the PowerTap power meter pedals that Quarq acquired, and recently discontinued. cassette is 40 EUR. 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. Makes 0 sense! Their single sided power meter is 349? Ultimately, itll be interesting to see where this goes. I currently sort of relate power meters to HR monitors, while swimming: not enough real world data to provide actionable real-time feedback. This power meter fits SRAM RED and SRAM Force 8-bolt crank arms. Shimano recently updated its compatibility chart . I can say that in terms of total power, the spindle isnt a good place, because itll only ever measure the left side. Regarding chainrings, the power meter is compatible with SRAM AXS 107 BCD 1X and 2X chainrings as well as other, 107 BCD 4-bolt chainrings. old Calipers, new STIs)? I have just installed the Quarq Rival ASX wide 1 powermeter (upgrade option) on my Force ASX 2x 43/30 gravel bike. Meanwhile, we weighed Shimano Dura-Ace at 2,514g when we tested it . Yes, just saw your comments from mid August after I dumbly posted, my apologies for making you repeat yourself. or to get Garmin SPD powermeter (super pricey!). I think for any bike industry person, its pretty much known that you might show up at an event and have a bike thats not quite the right size. Either you have JavaScript disabled or your browser does not support JavaScript. VeloNews, CyclingTips and Peloton have become VELO. Shrug, a day on a bike is still better than a day not on a bike.). But thats not the market here. So I consulted the engineers at 4iiii, sent them data files from all three bikes/PM sources and while there was a significant difference in the 4iiii values, their engineers maintain their unit is accurate. On the other hand, using the previous generation brake lever without SERVOWAVE with the new caliper design with 10% more pad clearance does in fact work because the pistons in the new caliper are a smaller diameter. Id really wanted to use my AAA Eneloops. Material: . Is every PM manufacturer using the same algorithms to do this with the same parameters (or are they even doing this at all, since most PMs are meant for paved roads)? If they sent you a 172.5 and you have a 170 or 175 on the other side, that would totally explain a significant left/right skew due to the leverage ratios for a spindle-based meter. On the dual side versus one side conundrum, here is my perspective and personal experience. Im from out of the country and will be visiting the US, whats the best triathlon shop in city XYZ? Trek BB95 Campagnolo crank arms and chain rings. Our slippery fork features KVF aero legs to minimize drag, while the unique molded carbon dropouts reduce weight. H1.5 geometry, developed with Trek-Segafredo pro cycling teams, puts the rider in the optimal aero race position. Does it affect the accuracy of the measurement? EDIT: Seems I may have found an answer on the SRAM site, and it looks promising. SRAM Force eTap AXS 2x12 wireless electronic drivetrain, hydraulic disc brakes, a SRAM Force AXS power meter, an aero handlebar that's compatible with clip-on aero bars, and a pair of tubeless ready Bontrager Aeolus Pro 51 OCLV carbon wheels. Let us just assume your FTP is 300 Watts and now you are planing to do some intervals an your PM reports 15% lower numbers, you suddenly need to push 345 real Watts which is well into the VO2max territory and you would not stand a chance to complete your 20 minute intervals. Follow the steps below to upgrade to an eTap AXS crankset and power meter on your Cannondale Ai frame. Only other option for me would be to get Favero Assioma and covert it to SPD with DIY (pricey!) Carbon wheels can lighten your ride and improve your performanceand when you ride Bontrager, your investment is protected. In other words, looking at the larger the data sets of power meters and trainers I have over the last 10-12 years of testing 2-4 power meters on every single ride year after year, the more Im coming to the conclusion that there are so many ways for power data to be inaccurate on any given day from any given vendor, that the left-only doubling thing probably is a wash in the end. Using this combination will create more free stroke in the lever action and ultimately does not produce quite as much maximum braking force, but the braking performance will still be smooth and controlled. It is not as light and stiff as the version above, however because it uses replaceable chainrings, it will last longer and allows you to use either 1x or 2x chainrings. I recently entered the gravel discipline after being a roadie for 30 years. As I read all the other AXS reviews that came off embargo last week, most read like cut n paste from press release content, with a few others going a bit further and providing high-level commentary about the importance of bringing the price down on electronic shifting. Am I right in thinking this will only work with a Rival AXS crankset I cant retrofit it to an existing non AXS Rival Crankset? Equally far off 40-50w total power. To get the benefit of a 52 Shimano large ring with a SRAM 10-tooth cog which is a bigger gear than a 100% Shimano 54/11 but with less cadence jump between gears, the best of both worlds would it be better to run the SRAM chain, or the Shimano chain? At that point, the difference shifted to 30-40w offset. From the SRAM response last week, it is apparent that the spacing between cogs in an AXS cassette is less than on other 12-speed cassettes; that was the reason for making the chain plates so thin, thus mandating the taller plates and rollers. However, SRAM did make an 11-speed eTap WiFli rear derailleur that would definitely handle a 32-tooth rear cog and maybe even a 34. Once I get above my FTP for sustained periods, I tend to see my power balance shift a bit. Are you willing to review or test beta products? So Ive got a few rides on this, and its been a mixed bag. No one would accept such discrepancies on any sort of measuring device. SIGN UP FOR EXCLUSIVE OFFERS, UPDATES AND PROMOTIONS! 125 EUR the rear derailleur. On some bikes, there is not enough room between the left crank arm and the chainstay for the sensor to clear the frame. While perhaps there is sufficient tooth engagement that chain skipping is not a risk, it does at least mean that the chain is following a larger-diameter circle, meaning that your effective gear size has increased. Because the power meter wont be able to measure where their fitness really stands. The single sided power meter can be infinitely precise as much as it can, but it wont change the natural body imbalance (about 2% typically for most people). Sram Red Axs Quarq Power Meter Crankset, Speed: 12, Spindle - Target But perhaps more interestingly for some readers here, it introduces an entirely new type of power meter for Quarq, SRAMs power meter brand: The Rival AXS power meter. For this to make sense, you need also to keep in mind that your imbalance will also tend to be random, depending on your shape and on the cadence you ride at. has anyone tried fitting a quarq spider power meter to a rival setup? Hey Ray, And the imbalance varies depending on power level, among other things. If I know more about power meters I know that in general, more things can go wrong with pedal-based power meters than other places. At this point, it was time to get out on the road and testing. Why not test with other pedalsbased powermeters? Havent heard anything since. Calibration offset is all over the place as well and will jump up and down significantly during single workout sessions. All this matters because if your power shifts based on intensity, or some other factor, then its hard to do any comparisons.
