I like every thing about my new 840. It's got so many features I initially had to turn some off or I'd be overloaded with too much data. It's quite an improvement from my 520+ which wasn't holding enough of a charge for long rides. i like the longer battery life and now find I only need to charge it after 3 or 4 rides. The only negative is that the buttons don't seem to engage after clicking them so sometimes I need to hit them more than once.
This is my 3rd Garmin bike PC. Needed to upgrade from 5-year old Edge 520. Buttons were disintegrating, falling out, and frequently losing connectivity with cadence sensor & heart rate monitory on Garmin Venu 2 Plus watch. Didn't want to spend a lot of $, as use Bike PC for principally for display of data, and rely upon Garmin watch to upload ride data to Strava. Edge 540 fit the bill. Not too expensive. Meets all my requirements. Still learning to use new functions.
Garmin has responded to ongoing criticism regarding the outdated appearance of its display technology by introducing significant upgrades in its devices. Following the successful implementation of vibrant and responsive AMOLED displays in various Garmin watches, the Edge series is now receiving similar enhancements, beginning with the Garmin Edge 1050. This model features an impressive 1,000nit display that rivals the responsiveness of modern smartphones, while also offering superior battery longevity.
In addition to the upgraded display, the Edge 1050 incorporates a range of new features designed to enhance group riding experiences and engage with the broader cycling community, including a crowdsourced system for identifying road hazards. Notably, the device includes a well-executed bike bell feature. Furthermore, Garmin has made substantial improvements to its gradient responsiveness and other performance algorithms.
Dove fully into the Garmin ecosystem. I utilize their Rally power meter and this pairs so well with it. Great to have for navigation, you can create routes on the Garmin Connect website and seamlessly upload it to the Edge. I also love the data it provides with my Rally power meter. Great piece of technology for any serious cyclist. The touchscreen capabilities along with buttons make the 840 a better choice over the 540...plus more storage on the 840. It's a little more expensive, but you get what you pay for. It's worth it. Fantastic computer!
