A lot of excitement was built up this summer around COROS’ first bike computer with “leaks” from pro riders at Outbound to the build-up to the official announcement on June 17th – COROS’ bike computer was poised to be something fresh and unique with insane battery life at a budget-friendly price.
The catch? The software wasn’t actually ready to review on the announcement date and it now looks like they’re also revisiting the hardware with a shift in the delivery date to September 2024 from the original July 15th date (in actuality, the original ship date was supposed to be July 1st but was postponed due to software).
COROS states that the reason for the delay to September 2024 is due to a possibility of the quarter turn tabs on the underside of the Dura failing with some 3rd party mounts – the interface isn’t as precise as they would like it to be. I’ve been using the Dura for nearly 6 weeks and haven’t had an issue but I can confirm that it’s not a super snug fit with some of my 3rd party mounts.
COROS is actually still shipping some Duras though, specifically those placed on pre-order if the customer chooses to receive a 1st-run unit. Customers who pre-ordered the Dura were given 3 options: 1) Receive a 1st production run Dura and then they can exchange it in September for a 2nd run Dura with the updated tabs. 2) Receive a 1st production run Dura and not choose to exchange it but rather have a 3-year warranty instead of the standard 2-year warranty. 3) Get a full refund.
Putting the hardware aside for the moment though, the software still isn’t ready for prime time. I tested their latest firmware which was supposed to solve some issues I encountered with my initial testing but some are still present – notably issues with turn by turn notifications where on some occasions there would be no turn indicator what so ever as well as incorrect notifications, such as turn right but I really should be turning left.
These routes were created in Strava and validated to work correctly on a Garmin Edge 840 and Wahoo ELEMNT ROAM V2.
On a good note, on-demand, automatic rerouting is now working quite well for me where if I deviate from the intended route, it will generally do a swift and decent job in getting me back on to my intended route. I found it to detect if I’m off route within about 30-50 meters of deviating and can calculate a path to get back to my intended route within about 5 seconds. It worked very well as long as the Dura was connected to the COROS app on my phone but there were a few occasions where the Dura lost connection with my phone even though it was in my pocket.
Speaking of lost phone connections, I’ve also had occasions after saving my ride where the Dura could not connect with my phone and it would prompt me to upload later via WiFi.
When it comes to “sticky watts” (where a device records overly-smoothed-out power data), I have not experienced excessive “stickiness” with the Dura where I’d call it “tacky” at most. I’ve been using the Dura with Garmin Rally XC pedals, a KICKR V6, a KICKR CORE, as well as a Tacx Neo Bike Plus – all using ANT+.
It wasn’t quite as granular as what a Garmin device records but certainly not the level of stickiness that I see from Wahoo.
Delaying the Dura until September will most definitely hurt sales for COROS where they’ll will miss out on prime cycling season but this could ultimately be the best decision where it allows COROS more time to dial in the software before the majority of customers receive it.
