The new fork also increases lateral stiffness for ultra-precise handling. 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 ). Only other option for me would be to get Favero Assioma and covert it to SPD with DIY (pricey!) 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. I think for this, the argument against single-sided is pretty obvious, ignoring the other potential variances in any PM being discussed above. At this price, if compatible with regular Rival, Id buy one today. Would 2 workout files (one from my Fenix and one from a Garmin 530) be interesting for you? Sure, temp comp might not be perfect, but frankly itd be quick enough that neither units materials would shift that fast anyway. If I look at my regular bike data from earlier this week, Im just fine balanced at 50/50 for the ride. 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. Thus, out I went again an hour ago for another loop this one about 40 minutes, inclusive of some gravel terrain as well. I am trying to understand SRAM, but come on, whats going on here. For months, the values coming from the 4iiii PM have been off the charts. 2.5 clearance, road q-factor compatible . But at the end of the day, you might just be wondering What does Ray use when not testing new products?. Force AXS Power Meter Upgrade. I was trying to aim for stability after the trainer test seemed to go well, and then obviously, things went not-well.. Model #: 00.3018.206.165. Force AXS Crankarm Power Meter Upgrade | PM-FRC-ASSY-D2 - SRAM SRAM seems to be shameless. PM-FRC-ASSY-D2. I have a SRAM Force crankset. What power meter can I use? 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. SRAM RED/Force AXS 107 BCD Power Meter Spider Favero claims too work (I havent seen independent any numbers one way or other other if it actually does), Power2max claims to as well (very non-confident in this claim). I can not use a spider-based PM as my crankset is too small (43/30). Today SRAM announces their latest RED groupset lineup, SRAM RED eTAP AXS for road and off-road. While it might seem that, since the teeth are still the same spacing apart, the standard-diameter rollers of the chain will roll further forward in the larger AXS tooth valleys yet perhaps still hold firmly on the teeth, the chain width could be an issue. Price is 270 in the Uk. Once they drop it back off, then Ill give it a whirl again. Shimano recently updated its compatibility chart . ROTOR does as well (very confident in this claim however). When looking for accuracy, consistency, compatibility and just gravel bike power values, is it too much to ask that my PMs produce similar values across bikes and disciplines? I tried setting the Kickr Wattage from 100 to 200W in 20s Steps and the Power seems to read as good as left leg only could be. For example on the trainer coast along at 180 200 watts for a while it reads relatively matching my assioma pedals. Has any recent testing been done om this PM? Enjoy, and thanks for stopping by! But then one of the SRAM engineers brought up an interesting point, looking at the previous data set with Rally the left-side of that set actually matched the left side of the Quarq/SRAM Rival. It also eschews any mechanical only version of the setup, going with only their wireless eTAP shifting option. At least it creates additional options for bikes with SRAM AXS Wide 43-30 cranksets. Im willing to accept that and do most of my hard training on my bike with the spider-based power meter when I want to be sure that Im getting the best numbers to analyze or send to my coach. 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. Once the surface becomes rough, everything becomes much harder. Would the chain slip under full sprint power? What Im wondering though is if it is compatible with non-AXS. Obviously, that doesnt apply when a unit is 30-40w off, but when were talking sub-10w, thats less precise as people might believe. I can upgrade my Rival to a PM or I can shed a ton of weight and go with a non-PM crank. They just had to agree to disagree. I am an amateur (ethousiastic bike rider) and I would like to see progress (or decline) in my power numbers. 2023 SRAM Force AXS Details If you recall, Red eTap launched as its sole 12-speed electronic group. Finding the right blend can be tricky. Unlike past Quarq spider-based systems, this spindle-based system is more akin in functionality to a left-only single-sided power meter. 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. Probably a one-off for demo purposes to show off the colormatching SRAM stuff? See more Maybe they changed shape and/or sizing just enough to keep them isolated, but we wont know without info from SRAM. Ok, thanks for the answer. Interestingly, below my normal power range (easier pedaling), it also shifts. That below with the hole, is the spindle, that piece that connects your two crank arms together: This is different than the rest of Quarqs power meters, which are spider-based and measure total power (but can vaguely estimate left/right balance). In general, as long as the ride is under about 2.5hrs, I can usually ride just about anything no matter the size. Power meter pedals can be installed on any crankset. DUB => dubstep may be my favorite botched autocorrect ever! 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). Please email us veloqna@comcast.net to be included in Technical FAQ. Bike compatibility: Road. But also, to potentially increase overall power. You're serious about speed and performance, and you want the advantage of crisp wireless electronic shifting, lightweight carbon wheels, and the all-weather stopping power hydraulic disc brakes provide. 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. The most common question I receive outside of the whats the best GPS watch for me variant, are photography-esq based. You should check out my videos. 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. Battery Duration: 400 hours I am not talking about 1 or 2 percent, but something like 5 or even 10 percent ist pretty noticeable. Please see the Compatibility tab on the product page for more information. Crankset: Compatible with SRAM 8-bolt road and gravel cranksets; Chain: Compatible with 9-, 10-, 11-speed drivetrains. How much would drivetrain durability be impacted? The quick pad engagement of the latest system is a product of the brake system as a whole, so both the new caliper design as well as the new brake lever. Its definitely compatible with other AXS cranksets it says that on the documentation. My best guess here is that this bike is too small for me (it is, considerably), and thus, my pedal stroke is substantially different. Id be interested to know this too. Even more so if you then use that power to moderate race efforts. You can also use it with apps like Zwift, TrainerRoad, Rouvy, The Sufferfest, and more. At that point, the difference shifted to 30-40w offset. If i calibrate the Sram then it starts to read consistently with the pedals. why the sport is dying faster is the US than in anywhere else). This might indicate that each cog in an AXS cassette is 0.25mm closer to the next cog than in a Shimano or SRAM Eagle 12-speed cassette (due to the differences in diameter, it is not easy to measure the spacing between cogs in a cassette, just as it is a challenge to measure the spacing between front chainrings). But the next Sprint will cause it to get out of whack again. If others have similar experience, Im curious if total power output increases after addressing imbalances. The price of some of the recent SPD-based power meters was kind of shocking. Read this article on the new Outside+ app available now on iOS devices for members! Seems like the issue has been resolved in its way. So basically, single sided power meter are not much useful. So im looking for a power meter for that bike, but as I come from a Kickr Core and the So Ill place my girlfriend on my Kickr Core and test at various Powers (50-200?) Thank you for this review. SRAM RED AXS Power Meter Crankset 165mm 12-Speed 48/35t DUB Spindle. Im not sure one way or the other in terms of the best place for power measurement at a technical level. You get the free speed, aerodynamic advantage, and superior ride quality of our ultimate race bike, plus the precision of a wireless electronic drivetrain. Neither one of us have ever had an issue with power balance so we no longer use left/right power and we would rather have a system dedicated to the bike rather than hassle with changing pedals bike to bike. 3s Power and TSS type of stuff are enough. Any Update? This is basically a groupset to punish the normal people: only one leg only power meter, no compatibility with Force and Red. No one would accept such discrepancies on any sort of measuring device. I havent an account here to compare the powerdata. Best Bike GPS & Cycling Tech Buyers Guide, PowerTap power meter pedals that Quarq acquired, DJI Air 2S In-Depth Review (with a Sports Tracking Focus). These companies release their best and fanciest stuff at the top end, and then roughly every 1-2 years it trickles down to the next level, and so on. Get a bloody graps of reality !!! After all that was done, I started pedaling. BB Compatibility: All SRAM Road DUB BBs, except Ai, All SRAM Road WIDE DUB BBs, except Ai: Speeds: 12: Chainring material: No rings: Bolt . Power Meters | SRAM Uses a CR2032 battery that lasts for 200 riding hours and changes without tools.
