I had an Edge 530 for several years before getting this, and I loved it. Upgraded to the 840 because it was a good price and waiting to spend $200+ more on the 850 didn't seem worth it. This is definitely a good bike computer--it does everything you could ever want and lots of things you'll never want, or even be aware it can do. That said, I knocked a star compared to the simplicity of the 530 because this thing is beeping at me and throwing up ClimbPro screens constantly, and it had a run where it wouldn't wake up without me hard restarting it several times (that seems to have gone away for now). You can change the settings to make it beep less and turn off ClimbPro, yes, but it's so excessive out of the box that I have to point it out. And I liked ClimbPro a lot on the 530, but this thing considers EVERYTHING a climb. Literally, any incline it seems. I actually got lost on a long ride because the computer kept throwing up ClimbPro and the new hazard pop-ups over my navigation as I was going 20+ mph and I had to stop, figure out how to exit back to my nav, turn around, try to figure out where I was going in advance (because when I went back the screen popped back up again), etc. If you can't tell, it got in my head a little. BUT, with all that behind me, this thing is a darn good computer.
I had the Enve/K-Edge single piece computer mount but when I got the Garmin Edge 1050 it wouldn't fit. This Silca titanium mount fit well and was 9 grams lighter (including the bolts, puck, and the light mount - 36g vs 45g). Plenty of space for the 1050. Two annoyances: 1) this is Enve's fault but to change the computer mount you have to completely remove the top front clamp because the computer mount bolt doesn't have clearance. This means you need to mark exactly how your handlebars were set up, fully remove the piece, then remove and replace bike mount, torque it (I did 5nm), then reattach and set up handlebars again then torque the top front bolt and the two front bottom bolts. This was helpful for the sequence and the torques to use: https://youtu.be/jTVowwKnNKs?si=MyntB8diG-SHrS5U
So, what should be a five minute job adjusting one one bolt is more like a 30 minute job.
2) the Garmin 'puck' that comes with the Chisela only works to turn in one direction. I am pretty used to being able to quarter turn in either direction to release. This is Silca's choice and they'll probably say it's more secure or break resistant but it's different from every other Garmin mount I've used.
The light mount works well and has a really nice threaded end to receive the bolt which gives me confidence this will last and not get stripped.
One odd thing - the K-Edge bolt had a metal washer whereas this doesn't include one. If I get rattling I'll transplant the washer.
Upgraded from my 530 after 4+ years. I'm pretty much purely a fitness and training user and rarely use the maps. It has been a welcome upgrade for a number of small reasons. The screen is brighter, easier to read, and more responsive. USB-C charging seems faster and is definitely easier to use. And there are several features for power, climbing, and stamina that are either new, or were so buried on the 530 that I never found them. Transferring my sensors via Garmin Connect was automatic, and wi-fi connectivity is exponentially improved. Bottom line is that this is a much more polished platform than the 530 and for me it was well worth the upgrade.
I never owned a Garmin before, but I'm getting back into cycling after a few years off. I plan to use GPX files to participate in cycling events and train for a century ride at the end of the season.
After using my Garmin 530 for a few months, I can't imagine riding without it. The navigation works great, and I appreciate being able to track my heart rate, cadence, and other metrics.
I prefer the button interface over a touchscreen, as I can't stand having fingerprints on the display. There is a bit of a learning curve, but it's manageable and straightforward.
I would definitely recommend this device to anyone serious about cycling; it's a must-have.
