Sigma Rox 12 Review

The Sigma Rox 12 is a mid-sized, BIKENAV with some good features for STRAVA officianados and efficiency cyclists alike.

Right here’s the evaluate summary with LOTS of detail afterwards. Take pleasure in.


  • Worth – 90%

  • Obvious Accuracy – 85%

YES, the Rox 12 is very functionally-competent nevertheless it has a couple of rough edges each when it comes to its seems to be and when it comes to how the whole platform gels together. However, It’s undoubtedly value considering, particularly should you assume Garmins are too highly-priced. The Rox 12 provides you lots of bangs on your buck, just when it comes to the sheer number of features and high quality development.

If it’s worthwhile to navigate a LOT or should you like to use STRAVA’s routes & segments then the Rox 12 becomes much more compelling. While it does have very many options for the efficiency athlete, I think that lots of those sorts of potential buyer will look as an alternative at Garmin because of their help for less widely-used features like 3rd celebration coaching platform integration, sensible trainer management and the pliability offered by Garmin’s CIQ apps.

But most of you’re NOT efficiency athletes so why would you select the Rox? Perhaps the worldwide maps may tempt you or perhaps you would like to get a couple of more stats from the manufacturer’s analytics platform than Garmin?

  • No ANT+ RADAR/Mild help
  • No reputation routing
  • Can’t use personal maps

Sigma Rox 12 ReviewBackground

The Rox 12 was released in Spring 2018 and represents the beginning of another era of motorcycle tech from Sigma Elektro GhbH. This evaluation is written a yr on and so bugs could have been fastened and new features added.

Previous generations range from their primary ‘BC’ fashions via to the Rox 7 and Rox 11 GPS models which might be still bought. However the Rox is a really totally different system and along with the current, value-for-money Sigma iD.TRI watch, I see an organization that has a cunning plan to enhance its market position in a number of areas.

Rox 12 Impressions & Overview

Let’s start with a comparison to comparable bike navs. Here you’ll be able to see that the Rox 12 is mid-sized however unusually extra elongated than the others, maybe higher suiting it to displaying extra of the upcoming route when navigating as well as making it fit higher in your palm when carrying it. There’s plenty of ‘bezel’ compared to the display measurement and the display space itself isn’t dissimilar to the Karoo and Polar V650 despite the totally different form.

Sigma Rox 12 Review

It feels strong & well-made. There are 6 buttons and a touchscreen and whilst the buttons don’t seem like they’ll work too nicely, they’re truly fairly good. Also surprisingly good is, at the very least superficially, the touchscreen.

Sigma Rox 12 Review

Virtually equally, you should use the buttons or touchscreen to navigate around the system. There are, nevertheless, exceptions which require the touchscreen like the swipe-down display and when selecting a selected route from several introduced on the display.

Sigma Rox 12 Review – Unboxing & Setup

Sigma Rox 12 ReviewI don’t often spend too much time on this part however, for once, it’s value stating that you simply additionally get a strong, Garmin-compatible out-front mount with Go-Professional underside adapter, a stem mount, a tether and the costlier bundle also has a dual-band HRM and dual-band velocity+cadence sensor thrown in for good measure.

The mount and all the accessories are well-made, certainly the HRM strap appears similar to an earlier Polar mannequin. It’s a nice contact that the HRM broadcasts over BLE and ANT+.

The Sigma app kinda doesn’t work at all with the Rox so modifications to Sports profiles and sensor connections aren’t potential on the app and may as an alternative be completed on the Rox or on a computer by way of Sigma’s DATA CENTER.

Sigma Rox 12 Review

Superficially you’ll discover that a ‘normal’ coaching or commuting setup with the Rox 12 is just like many different units. It’s additionally well-functioned for outside utilization and could in all probability might be classed as a ‘performance’ cycling pc relatively than just a BIKENAV.

You possibly can create numerous sports activities profiles with up to eight pages per profile (plus lap pages) and may have as much as 10 knowledge fields per page. Knowledge fields are often numeric but in addition embrace MAP and WORKOUT PROGRESS graphics.

Sigma Rox 12 ReviewA check that I exploit to evaluate if a tool takes efficiency utilization significantly is that it might display a “last lap NP” mainly because so as to be able to do this a number of other issues additionally have to have been carried out like energy meter help and FTP/power zone help in addition to a ‘bit of thought’ being utilized in the design process. Additionally, by noting help for ‘last lap NP’, then you definitely’ll virtually definitely have IF and TSS too. YES, the Sigma Rox 12 passes this check with flying colours!

Indeed if I also advised you it supported Rotor’s show of OCP and OCA for eliptical chainrings then you definitely might be much more impressed…when you knew what I used to be speaking about! (It’s a bit like Garmin’s “Power Phase” metrics).

Sigma Rox 12 Review

Most sensors supported – notably lacking is VARIA LIGHTS/RADAR

In ‘normal’ utilization, the Rox 12.0 is complete in what it gives. I’m positive a primary knowledge metric or two are missing however there are greater than sufficient knowledge metrics for me, though perhaps the one factor that IS missing can be more aesthetic dials, graphs and different graphics eg a FUEL GAUGE show for HR; a graphical indication of which gears Di2 has put you in; and a prettier elevation profile.

Common Training Utilization

I’ll cowl specific coaching situations in a minute but upon getting the Rox all arrange, you can see that the general quality of workout-based interaction with the Rox 12 is sweet.  The buttons are sufficiently straightforward to press and the touchscreen appears to virtually all the time work and could be very responsive as is the overall interplay with the Rox 12, although typically it is sluggish to load longer routes (eg 100km). In the event you don’t like touchscreen then most things seem potential with the buttons. There’s audio suggestions too and that perhaps might do with being a bit louder however it’s alright.

Aside from that, it’s a great bike pc. It does the standard stuff.

Navigating on the Sigma Rox 12

The complete routing offering from Sigma is impressive and doubtless as full as a high spec Garmin Edge 530/830 though not as pretty-looking as Hammerhead’s Karoo.

The very first thing to keep in mind that differentiates the Rox 12 from some rivals’ products is that the Rox 12 has ROUTING INTELLIGENCE with an actual onboard map with a Digital Elevation Mannequin (DEM) built-in. But in addition to an understanding of hills, named roads and junctions, it also has additional routing intelligence, presumably by way of map layers, that permits it to offer you routes applicable on your present biking exercise sort eg MTB, Hybrid, Street and so forth.

Rox 12 knows what a junction on a trail “is” and may give you turn-by-turn (TBT) instructions.

The Rox 12 will get you from A to B in 8, sure eight, alternative ways.

  1. Road – Navigate to a road
  2. Draw – Create a route on the Rox 12 together with your finger. It snaps to the roads and off you go – it really works, it’s clever but it’s tough to use.
  3. POI –
    • Local POI – navigate to a POI close to you eg a Practice Station or a Cafe.
    • Remote POI – navigate to a POI to near some place else
  4. Map Point – pan, zoom and choose a single point
  5. Current – repeat a current navigation of any type
  6. Favourite Level
  7. Pre-loaded route/monitor
  8. GPS co-ordinates

Sigma Rox 12 ReviewHowever it’s even intelligent than that and there are lots of subtleties to a number of the strategies of navigation. When the Rox creates a route it all the time appears to use roads or trails and never ‘as the crow flies’, which is ok I assume however for all these navigations you possibly can select the shortest or best routes there and you may change the priorities given to cycle routes, major roads and unpaved roads. You’ll be able to reverse a route or your current journey, so as to get you residence. Whenever you select to comply with a route, you’re prompted to navigate to it and, cleverly, that may either be to the beginning of the route or the closest level of the route.

In case you are grabbing a route file from elsewhere then you definitely may use your routes on one of the related providers, specifically STRAVA, KOMOOT or GPSies, every of which has biases to sure forms of public routes which you could grab. I’d wish to see integration with RidewithGPS too.

Handily, you possibly can load a route using the ‘old skool’ drag and drop technique onto the TRACKS folder on the Rox and I feel you can even insert an mSD Card and grab them off there (not tested) however you’re in all probability greatest, as an alternative, utilizing the Sigma software program.

Sigma Rox 12 Review

The only major omission is an enormous one and that’s POPULARITY ROUTING.

With no smartphone link I can’t see how any form of stay reputation routing can be attainable whilst leveraging a third get together service like Google Maps, nor will Sigma have enough of their own international usage knowledge to really create a very common route for you to comply with. You possibly can create a reputation route offline in fact – just create a free Garmin Join account and obtain a gpx file from there…super easy, there are simple ways to grab a Google Maps route URL and convert to a GPX file too – use one of many free on-line conversion instruments for Google Maps (you should use Hammerhead Karoo’s portal for that too)

Routing – Comply with a Route

Usually, the routing experience of the Sigma Rox is excellent. By “very good”, I imply that well timed and actionable instructions are given to get me from A to B.

The turn-cues are given properly forward of a turn and are clear to learn, accompanied by a clear, audible alert. Maybe it might be a bit louder however it’s high quality. The display attracts and re-draws in a short time with only a few delays (usually none) and the colours used are straightforward to interpret, IMHO.

The route-following experience is richly full of many features, including the power to see an inventory of turns and the power so as to add a roadblock to drive a re-route.

The algorithm for re-routing after a fallacious flip additionally seems surprisingly good. (I’m going to try to break it!!)

Strava Segments & Strava Routes on the Sigma Rox 12 Review

With a Premium STRAVA account, you may be good to go together with Sigma’s superior implementation of help for STRAVA, which is likely one of the greatest that I have seen now that it has been stay for a couple of months.

Listed here are the headline STRAVA options on the Rox 12

  • Up to 100 of your favourited STRAVA LIVE segments on your Rox 12 with leaderboard and your prime performances. You possibly can disable one among these on the ROX in case you have too many favourites.
  • Map and proximity views of your favourited segments – right here you possibly can hunt in your favourited segments, navigate to them after which be alerted as you get near them.
  • Realtime pacing of your segments’ efforts, supports segments-within-segments. I’m unsure of the precise technique Sigma used to pace you over the segments
  • Submit-workout performance stats of every of your completed, favourite segments on the Rox 12
  • Toggle from STRAVA Segments to STRAVA routes to comply with a route
  • Exercise sync again to STRAVA

Sigma Rox 12 ReviewNow that STRAVA has stopped supporting sensors by way of the STRAVA app, many more critical STRAVA users should depend on their cycling pc for the complete STRAVA experience. The Rox 12 does that and moves past the smoke-and-mirrors promoting of a number of the competitors that claim to have ‘STRAVA support’ when, for them, STRAVA help just means syncing of knowledge TO STRAVA.

I have to look a bit more at exactly how the in-Phase performance pacing works, it can possible have the ability to be improved. For example with physiologically-based efficiency cues like Xert carried out with their (free) SEGMENT HUNTER, but I can’t see that being utilized by any bike pc vendor aside from Garmin. In any case, Xert might be just for the extra critical performance-cyclist.

Coaching Planning, Scheduling plus Complicated, Structured Exercise Creation

Sigma Rox 12 ReviewWhile the Rox 12 does help complicated structured exercises, there isn’t any help for any sort of calendarisation of workouts and 3rd social gathering plans. Also lacking is FE-C trainer management. These are the widespread, major practical areas that the Rox 12 lacks. To compensate for these omissions, Sigma allow you to create complicated exercises both instantly on the system or on-line within the DATA CENTER. Either approach, your units’ exercise library is synchronized and backed up.

Complicated, multi-stage exercises may be constructed with repeated intervals and restoration durations based mostly on heart price, time, energy, period.

Whilst super-complex objectives cannot be set, like a certain Training Impact, and nor can intervals be nested inside intervals. Nevertheless, the functionality offered will virtually definitely cover the wants of the overwhelming majority of cyclists/triathletes.

Executing a Structured Exercise & indoor trainer help

While doing the research and testing for this Sigma Rox 12 evaluation I was, unfortunately, going by means of an extended interval of indoor coach use, so there wasn’t a lot knowledge to capture on the Rox nevertheless it did present a perfect alternative to play with the Rox 12 as an alternative of watching a field set that I didn’t actually need to watch.

Structured workouts could be started in any sports profile, indoors or out. There’s a special, configurable exercise display where you possibly can add further metrics to suit your training. Nevertheless, the primary ‘workout’ knowledge subject is fastened and is a nice, clear progress bar of the present interval.

There isn’t a FE-C help to regulate sensible trainers, thus a sensible coach will, simplistically, simply appear to be a power meter so far as the Rox 12 is worried.


Like most units, the Rox 12 doesn’t have any specific climb-focussed functionality. Nevertheless, when following a route it exhibits the upcoming elevation profile and you may modify the zoom degree to roughly match the length of hills you’re climbing. In that respect, it’s similar to the Wahoo ELEMNTs.

There are about 20 climb- & elevation-related metrics so you need to be nicely sorted there in case you are all in favour of metrics like VAM and grade.

TIP: A common tip for those of you who need climb-related functionality. You might use fitfilerepairtool.information to mechanically create climbs as laps if you analyse your exercise or when planning a route, you possibly can you waypoints to characterize the starts and end of your routes. These will then offer you both climb specific stats for in-ride and post-ride usage.

In fact, when you’ve got chosen a STRAVA phase that just happens to symbolize a climb then you’ll get the STRAVA metrics as properly.

GPS Accuracy – Sigma Rox 12 Review

A Sigma Rox 12 evaluation wouldn’t be full and not using a good take a look at GPS accuracy and elevation accuracy, let’s do the first of those…GPS.

For those who assume this picture exhibits a glamourous journey subsequent to the gorgeous River Thames then assume again. There are some good STRAVA segments off to the West of the map however to get there requires traversing unpleasantly bumpy roads proper subsequent to the sewage remedy works. #LivingTheDream

On the zoomed-out degree, you possibly can see the Rox (Blue), iD.TRI (Purple) and ELEMNT (Inexperienced) are almost equivalent, although the second image exhibits some deviation when zoomed in however not more than Four-5m from the Rox, so all is sweet.

Just a little bit more element with the identical units on the same journey doesn’t present anything of too much curiosity. Maybe a number of the timber in the first picture trigger a minor GPS irritation? The fascinating thing for me was that this journey coated a couple of of the sections of my ‘normal GPS check RUN‘ and just being a metre or so further from the houses with a greater view of the sky and travelling extra shortly on the bike give usually MUCH better tracks. Nevertheless the one point of problem where the Sigma Rox 12 struggled was, unusually, when going previous the relatively (UK-) famous Sigma Sports bike shop within the 5th image. Perhaps the Sigma Rox needed to take a look at the awesome bikes within the Sigma Shop window or perhaps it needed to start out a trademark infringement lawsuit..who is aware of?! Either means the Rox deviated a bit because there are some 2-storey buildings near the street.

So I tried cycling close to walls and timber once more, some other place, on a special day yet obtained acceptable results [Rox blue, Elemnt Red, iD.TRI Green]. The fourth image is surprisingly good as it’s operating East to West about 2m from a 3m high brick wall virtually constantly for over 1km…Good outcomes from all (only a part of the wall section is shown).

Elevation Accuracy

I’ve obtained plenty of shorter, principally flat rides like this one which doesn’t reveal an excessive amount of about elevation accuracy and, because of end-of-season duathlons, I don’t have something larger planned for some time (I’ll add some extra charts in later, perhaps Nov). This can be a pretty cool efficiency although.

Sigma Rox 12.0 Review – Fascinating One-Off Points

These are some stand out options and fascinating ‘finds’

  • Rox 12 (but not iD.TRI) helps dropbox. This is awesome and really useful for me !!
  • OSM Maps
  • Micro SD Card is usually superfluous although can be used for map and route information
  • BLE and ANT+ sensor help covers most sensor varieties
  • WiFi upload of completed exercises and WiFi sync to online sports activities knowledge providers eg STRAVA
  • It’s attainable to attach the Rox to a WiFi hotspot on your smartphone when away from house.
  • Has a lanyard/tether slot and tether
  • A 5v/1A battery pack can be used for charging
  • I’ve had over 10 hours of battery usage with no recharge – display brightness and navigation/renavigation will decrease this degree of efficiency
  • The display is usually readable however polarised sun shades influence readability
  • A 300km limit exists for calculated navigation however a pre-prepared GPX monitor may be for much longer.
  • Hammerhead Karoo permits side-loading of Android apps, Rox does NOT permit this regardless of additionally being based mostly on AndroidNice to have vitamin and hydration alerts.
  • Rox generates TBT directions (cue sheet) by itself when loading from a route file that doesn’t include TBT!
  • Some good consumer ideas at Richard Stum’s website
  • Firmware features update record: here
  • There isn’t a guide although you may find a ‘user guide’

Sigma Rox 12 – Navigation Options

Sigma Rox 12 Review

The Hammerhead Karoo in all probability has the perfect thought-through navigation setting, they only have to implement extra of it to add extra FUNCTION to the sweetness. The Rox 12’s display is probably not as vibrant because the Mio nor as crisp because the Hammerhead, yet it holds its own on this company. The V650 and base-ELEMNTs don’t have routable onboard maps and so can’t match these features of navigation functionality that arise from that on the Rox. The Wahoo ROAM DOES have an onboard map that’s fairly properly carried out but yet the Wahoo nonetheless lacks behind the navigation performance of the Rox. The Brytons that I’ve used are relatively primary choices nevertheless they have a new Rider 860 which seems fascinating.

Prime-end Mio’s are highly practical navigation units and their 605HC has a vibrant display, equally, you already know that Garmin’s Edge 1030 and Edge 830 have plenty of nav functionality and often a better worth to go together with that. Garmin’s jewel-in-the-navigation-crown is reputation routing, no-one else can quite match that (yet).

Pricing, Reductions & Availability

Sigma seems to have rationalized their distributor community lately and the only consistent source I can find is amazon in Europe and Energy Meter City in the USA (hyperlinks under)

The costs proven listed here are for the essential bundle which incorporates the out-front mount and stem mount. The costlier ‘sport’ bundle additionally includes a velocity/cadence sensor and HR strap. There are a number of colour options and the coloured a part of the Rox 12 is interchangeable, which is a nice touch.
