A preview of the Sigma Rox 11.0


Just arrived is the Sigma Rox 11.0 GPS bicycle computer. This 73.5x50x21.5mm box of tricks is stuffed with all kinds of technology to record and display all the metrics you need, on or off the bike.

Sigma say the ROX GPS 11.0 is “the training tool for users with the highest demands.” So that describes most cyclists, we’re all obsessed with our data and sharing it with friends. The ROX GPS 11.0 could be the perfect tool for that.


Checking out the Sigma website, the Rox comes with a frightening amount of functions, way too many to list here. I’ll point you in their direction and let you see if there’s anything missing. Obviously not all riders will use all those functions, but it’s good to know that they’re there, if ever you do.

Some of the interesting ones are the ability to display Strava segments. You can load segments onto the Rox 11.0 via Sigma’s Data Centre. Once loaded you can view the fastest times and compare your own. Handy for a bit of cafe stop bragging!


Navigation is taken care of with a simple ‘bread crumb’ trail display. While not as detailed as a full map, I found these are usually ok, but you’ll need to be a little more attentive. Way-points with your own text can be added to any route and these are announced with an audible alarm. Handy for alerting you to tricky junctions or the last feed-stop on your route.

Custom sport profiles allow you to set up three pre-configured training profiles. You can set up three different types of bike and configure different displays for each. This could be useful when swapping from road to off-road, or training to racing. After all you don’t always want the same information when riding a sportive as you do in the middle of a road race. You can also adjust the amount and type of information on each screen from one to six fields.


The Rox 11.0 is Bluetooth and Ant+ compatible, so it can see it’s R2 and R1 sensors for heart-rate, cadence and speed. Not only can it connect to sensors, it can also pair with your phone. This connectivity allows you to pass data back and forth without any cables. The Rox 11.0 can also alert you to incoming calls or messages on your ride, if you want.

You’ll need to download the Sigma Link app if you want to enjoy all this smart phone fun, which is free for Android and iPhones. I previously reviewed the Rox 10 and found it to be a handy little GPS, capable of recording all my data. While the navigation is simple, it’s battery life was good enough for hundred mile off-road sportives. The review is here, if you want to compare.


I’ll be testing the Sigma Rox 11.0 out over the coming months, both on and off-road and will let you know how I get on.
