![]() "Calibrate" function do - and what's up with the number it returns? (See the section "Why does data extracted from my training device through Device Agent or WKO+ not match the numbers I get when downloading to that device's manufacturer's software?") Whether you notice discrepancies or not depends on the type of riding you do – are you on a trainer versus out on the road, do you stop for a beer in the middle of your ride and, if so, how long does it take you to chug the beer, etc.Īlso, here is an informative page from the WKO+ folks explaining why what you see in Garmin (and other) software may not match what you see in WKO+: WKO+ also "does stuff" based on pauses and their length, etc. There are differences in how the LYC and Garmin deal with pauses/stops. With the LYC, it can be configured (and I believe it defaults to ON)ī) Stopped Time. With the 310XT, this is OFF by default and can't be changed. I think the differences you see from a power perspective can largely be explained by two main factors:Ī) Zero Averaging. If I have my LYC and 310XT side by side on the same ride, I get different numbers during and/or after the ride. This appears to be more historical than anything at this point It took a while for some vendors (including Training Peaks, makers of WKO+) to make their software work with the 310XT data – this seems to be largely resolved now.ĥ. No ability to do a static calibration or "stomp test" ![]() See FAQ item #5 for more information on this – once you understand what is/isn't happening, it's largely manageable.Ĭ. Whether this translates into any tangible training benefit is debatable. The LYC display is limited to 1 screen with 3 data segments. Also, the Garmin displays are numerous and programmable, with up to 3 different screens per sport, and up to 4 data segments per screen. It's "cool" to be able to see everything in one place for analysis after your run/ride. You only have one device to charge, download, update, familiarize yourself with, there's a consistent UI between sports, you don't need to learn morse code to change settings, etc. More on the differences between the Elite+/Pro+/SL+/SLC+ below. ![]() This approach also lets you purchase the PT Elite+ (the entry level wireless model) instead of the Pro+ (the next step up). no duplicate head unit, HR strap, cradle, cables, etc.). It's cheaper because you don't end up buying two units that essentially do the same thing (i.e. ![]() This solution is cheaper - especially if you're considering a Garmin for the run anyway. Why go with the 310XT instead of just using the LYC?Ī lot of people are interested in power but scared by the cost. Whether or not the tradeoffs are worth it to you is something that you need to evaluate and decide.ģ. There are solutions to many, but not all, of these problems. I) If you get into a situation where you need to troubleshoot the hub with Saris' help, you will need a LYC. H) Some people that are exploring this as an option are new to power (like me). G) There have been some problems with how various software packages deal with data from the 310XT. The brief backstory is that Garmin essentially treated early adopters as beta testers for months with repeated buggy firmware revisions until, finally, it seems to be largely stable/reliable.ĭ) There are differences between the 705 and 310XT in terms of what they do/don't do.Į) It's unclear what procedures you can and should follow (and there's confusion regarding the terminology) for things like calibration, auto-zero, zero averaging, auto pause, etc.į) There is not a lot of carefully gathered data comparing 310XT and LYC. Those that weren't burned personally certainly read a lot about it. And, of course, it's made by the guys that make the hub.ī) It's unclear what you can/can't do with the 310XT as compared to the LYC.Ĭ) People feel burned by how Garmin treated people with the Edge 705. It's been around forever and a lot of people have it, so there is more familiarity and comfort with it. First of all, I think there are a few reasons for the FUD:Ī) The gold standard is obviously the regular PowerTap head unit, or "Little Yellow Computer" (LYC) as it's affectionately known.
