Sigma Rox 11.1 Evo Bikenav
Sigma has a good pedigree of delivering highly featured bike computers and has a decent customer base in mainland Europe. I looked in detail at the larger Rox 12 model back in 2019 and it had a great feature set in place then but never seemed to do as well with customers as it deserved to.
Their latest Rox 11.1 Evo is launching later this year and today we have a sneak preview of what will be coming.
What is Sigma Rox 11.1 Evo?
It’s a performance bikenav that leverages maps and other connected features from your smartphone.
Unlike Garmin, the design ethos of Sigma is similar to that of Wahoo Fitness with the Bolt in the sense that some of the bike computer configurations are performed on the smartphone app. This makes for a superior rider experience most of the time as the bike computer’s menus are more streamlined and relevant. However, if you want to change some screen settings, you need to have your smartphone app with you.
With a normal, smaller, format Rox 11.1 targets those of us who want performance features yet there is also a wide-ranging ecosystem for power meter support, Di2 support, E-bike support, crash detection, structured workouts and coloured data fields to name a few.
The features and specs are detailed further below and they are impressive. However, they are not all-encompassing and, for example, a performance cyclist might want Last Lap-NP. I usually look for the presence or absence of that metric and if it’s missing then there’s usually other peripheral stuff missing too.
That said, how many people really want Last Lap NP? Probably not too many (I do) but Sigma compensates for this with other advanced features like colour coded data fields which even Wahoo only recently introduced.
One of my criticisms of the earlier Rox 12 was that indoor trainer support over FE-C was not supported. Well…it is now.
Another criticism of the Rox 12 was that there was no smartphone app…clearly, there is now and the app looks to have great features including incident detection.
The Rox 11.1 seems to have skipped on the Strava Live Segment support that was offered on the 12.0 which is a shame as that was a nice implementation of Strava’s headline subscription feature. Similarly, Garmin Varia Radar support is also not offered.
There are no onboard maps.
It looks like offline breadcrumb routes are supported with some interesting data fields that can be stretched and squeezed to fit on screen just how you want them to be.
For those who will miss the ability to re-route there is also a live link-up to routing capabilities on the app. So, for example, you can be directed by the Rox’s link up to Komoot on your smartphone.
First Thoughts & Take Out
Sigma might be on to something here if they get the pricing right.
The Rox 12 from 2 years ago IS a good device. It had a few techy teething troubles but was nevertheless impressive. I suspect one reason it didn’t do better was its unusual screen shape and aesthetics. Well, the Rox 11.1 Evo is a modern-looking device without being too unusual…it looks OK albeit very slightly quirky!
The feature set looks like it will handle the needs of 99% of cyclists. If the Rox Evo works smoothly and mostly bug-free, then Sigma could be on to a winner.
I’ve not looked at what has happened with Sigma’s data platform over the last year or so. My thoughts before were that it was a bit clunky. Perhaps if there are better integrations to 3rd party platforms along a similar vein to Wahoo then those reservations would diminish.
I’m not sure I’ll review this when it comes out later in the year but let’s see what happens.
