Join Date Mar Posts 4, Sigma bike computer calibration one roll of the wheel from the stem back to the stem on the floor. Join Date Oct Posts 5, On the computers I've had, you actually measure the wheel diameter in millimeters and input the 4 digit number for wheel size.
Great ideas above re calculating actual circumference via wheel travel toothpaste!
Unfortunately my CPU did not afford a manual entry sigma bike computer calibration I used this table:. I chose to go down in value assuming that my weight will reduce the overall circumference as will treadwear, reductions in PSI, etc.
Figure it is not an exact science, but who cares? The relative values ride to ride, month-to-month of actual use are more predictive of what the sigma bike computer calibration counter or CPU in this case measure.
Home Questions Tags Users Unanswered. Bike computer wheel size setup Ask Question. The bike computer sigma bike computer calibration a Bontrager Tripthat comes with the following wheel settings: Yep, measure how far sigma bike computer calibration bike travels in one revolution of the wheel.
Even if there is no table in the manual, it's a simple math calculation to convert wheel circumference into wheel diameter, and you'll be a lot more accurate than feeding in a wheel size. And some computers let you feed in circumference directly. And it makes no difference how far out along the spoke you place the magnet and pickup, so long as it's reliably mounted.
The computer measures rotations. The problem with the simple math is that it doesn't catch the change in effective rolling diameter, which is impacted by rider weight, air pressure run, and sigma bike computer calibration tolerances. One of the pro tips for this is to use toothpaste. Put a line across the pavement, ride over it, and then measure between the first line and where the tire touches down again.
Batman Batman Some devices can even link up with smartphones and tablets through apps, giving you more power to develop training programs wherever you are. A good bike computer will either help you meet your training goals, or just give you an accurate snapshot of how you're doing on your stem cap mounted bike computer. Either way, make sure to take time to choose the right one so that you get the most out of it.

I suppose there is a rather powerful CPU so that they need a larger battery to achieve sigma bike computer calibration specified endurance. Ray, thank you for a great post which convinced me to buy ROX I had my first ride yesterday and I experienced a lot of the ghost turn notification you were writing about. They are coming way too often and make the navigation an awful experience.
When the map is showing you need to go right a sigma bike computer calibration tells you to turn left bike gps software for iphone reviews vice sigma bike computer calibration see the attached picture. Even if the current street is straight forward for a couple of kilometres, the turn notifications are popping up and tell you there is a turn.
Currently starring at the map is the only we to use this device for navigation. Do you know their plans about fixing it? Is this the best unit out there for these factors? Some of the comments on blogs about the Garmin Edge units make me worry about their navigation and re-routing Specifically the Plus, but it sounds gps-305 bike tracker the and share some of the same issues.
Is there something else Sigma bike computer calibration should be looking at? Hi Ray, maybe you have a recommendation. After your good review I got a ROX 12 yesterday and took it on a k ride today. Navigation sigma bike computer calibration ok, but to often I missed a turn because nothing was announced. Also the ghost best bluetooth speed and cadence sensor you wrote about.
But my biggest struggle with the unit is: Hooked to my MacBook and tried Sigma Software. Also, no Pm data. My forerunner 5 recorded the data perfectly. I was very exiceted based on the first impressions. Yesterday i went for the first ride. Tried several times to ervoor or restart, But the computer could not start up again…. Very disapointed a Did my ride without the sigma rox and i have to send it back to the online seller.
Anyone facing the same issue? Turn off the device push and hold the power button for at least 10sec 2. It will start sigma bike computer calibration the Recover Mode 4. Push the Home Button again 5. Select reboot option. Ghost turns — I have them too and using the unit off-road what I do most of the time yesterday during sigma bike computer calibration 60kms it made me turning off the navigation overlay function after the first hour.
I really want to go with this unit on the long run so I will contact the customer service tomorrow and see if they have a planned firmware update coming within the 14days I have before sending this back Gps odometer bike. Based on the review and some more investigation into Sigma I bought it as well.
Am very satisfied. I did find a few bugs which I reported to Sigma.
I was well impressed with the calibraton of their response. Within 30 minutes I had an calibrration and direct email. So mailed them the bugs I found and was told later that day a new firmware is in the making. Touch will be optimized, entering credentials related to the touch will be improved multiple characters with 1 click. Downloads of maps will be looked in to. Had problems downloading the maps of Malaysia.
Also a tomtom gps bike mount I had was to get the Rox 12 on my preferred network. The current limitation for the WPA calibraiton is 25 characters.
They are looking into sigma bike computer calibration if that can be higher. Only a username has to be entered. No password is asked. Just keeps loading and loading.
Directly through routes I can start within 5 seconds. So far Calbration had this wth tracks which were sigma bike computer calibration with Runkeeper and tracks downloaded from gpsies. The gpsies bug sigma bike computer calibration ridiculous. Separate keyboards for separate apps is also a bit annoying, but that is issue with most Android devices anyways.
Hey Ray, after reading your review I went ahead and bought one. When I go to the segments list it only shows 4 out of at least 20 that I have…Needless to say this has prevented me from testing the Live Segment feature.
I noticed that a maximum of 30 of my starred sigma bike computer calibration are copied to the device. This seems to be a limit that they put on it, which is pretty poor and renders Strava Live segments useless. Hay biie is the Strava bike gps pro segments cqlibration with the newest update?
Can you get more then 30 segments? Is the info good while on a live segments? Did a few resets, and at start it says cloud conected.
No help yet. Sorry for my english. When did you first contact them? Email to support They told me that they work at sigma bike computer calibration cloud server and maybe thats the reason. Today I called the support, sigma bike computer calibration no direct help. They told me they will call back, but maybe not today. Called me back today, to tell me capibration will call sibma tomorow to fix it.
I got turns where no turns are and sigma bike computer calibration the other side where really a turn has been i got nothing. So some times i had to ride km back to be back gps locator on bike route.
My Favero however is working — Before my morning ride today i needed to restart the unit a couple of times to connect to my Favero PM. Got it working somehow — In the middle of the workout the unit crashed something with Sigma App was written. So needed a restart. Parts of the workout where thus not recorded. Never had a crash with my edge So guess i will go back to that one. Navigation, Display size, overall layout of the ROX are very pleasant, but it lacks reliability.
Unfortunately, as always waiting for new devices announced until a stable firmware exists. But I think that Sigma generally makes it very fast and then the devices garmin edge 605 bike gps the software Sigma link and data center are very stable. I currently have the Rox 11 previously the Edge and have no problems with the sigma bike computer calibration and the software!
Hi Ray in your review it states its not designed for running sigma bike computer calibration there is a sport profile on the device specifically for running it would seem, so am in correct in saying it can be used for running or have I missed something?
If You are searching for something like that the garmin devices have always on option under the tracks and then You can colour them differently one-by-one the ROX 12 coputer not have it in this firmware version.
Sigma bike computer calibration was calivration what I was looking for. Does it have it for single route? Mmmm very mixed feelings. Just bought the Rox. Very reliable but I was missing slightly better navigation options. Setup took a while — had to reboot 2x times before it recognised my Di2.
But so far no luck on linking the Polar sensors. Sigma bike computer calibration a route with Kamoot. Loading went fine, but then … lefts are rights, bends in the road get a beep and arrow, but when I need to turn a real turn I mean — nothing. Also had 1 reroute missed a sigma bike computer calibration and it kept sending me in a loop. Halfway I thought maybe it was the Kamoot route.
So switched to the internal route calculation. So got bored and bike computer posts to strava the routing off. The resolution of the screen lets you down. For the price I was expecting a bit more. No info on website. I really like the options to go to the nearest point of a route, and also the recalculation workshop excellent. There is an issue with the sensors, which causes the crashes.
This is comparing tri computer for bike calculation to other apps and devices when the tire circumference is identical in each device. Did you do sigma bike computer calibration ROX 12 comparison of the distance accuracy when using a speed wheel rotation sensor? There are no problems with crashes. The speed and distance are accurate compared to other devices not using the sensors.
Tested this on short and long rides. Tell me I can turn routing off somehow? It says that routing maximum distance is km.
Agreed on the pricing. I own the Rox sigma bike computer calibration Tuesday 26 Calibratioj. To my disappointment, it did not best bike computer backpack to my Polar bluetooth heart rate and cadance sensors.
The only bluetooth sensor sigma bike computer calibration supported is that of the Rotor sigma bike computer calibration. It was initially a major disappointment, because I bought the Rox based partly based on the consideration that BLE sensors were supposedly supported.
There were some firmware issues also, which were also resolved completely to sigma bike computer calibration satisfaction by Sigma Sport. The superb follow-up turned the rather negative experience I was close to trading the device in for a Garmin to a very positive one. But please be aware of the lack of BLE compatibility when you consider buying this device. Hello mike I understand that for a combination with a power meter is perhaps better to prefer the garmin bik because it has the firstbeat metrics?
Compared to the elment bolt unit, it is more precise in determining the altitude and in managing slope and cadence I noticed that wahoo elemnt bolt has some problem of precision in this respect. Card is srm power control and works, checked the issue with another card in the ROX.
Who has the sigma bike computer calibration issue? Got a new firmware last week. Release Where and how did u upgrade to FW rev. Vike non-mapping offerings were included, so why not the mapping one? I had some photo comparison shots, but that was largely just a collection of units I had handy with me for other things.
They were also the most popular units out there. Ability to actually know the streets your on and re-route on the fly when required. Versus just having a breadcrumb trail overlaid onto maps that may or may not have street names. Maybe my previous post was unclear or too long, but I do want to help other people by preventing from running into the same disappointment as I had.
So here it is again: Calibrwtion comparison table wrongly states that bluetooth only sensors are supported. Sorry, I thought I had fixed it upon your first comment. Confirmed as fixed now in tables.
The only other niggly issue is that it only stores 30 Strava Live Segments at sigma bike computer calibration on the device. Ive got a question about the data Rox 12 can display during rides.
The trips consist of multiple mountains of different lengths and steepness. Can the ROX 12 display information about these mountains individually in one ride? For example, I want to see when the first mountain begins, how much km it is to the top and how steep it is. When the second mountain begins I also want to see where it starts, how much km it is to the top and the steepness. Sigma bike computer calibration, I want to see the complete profile of the gps cycling computers bryton 10 but also with individual information about the mountains.
Eigma this possible with the ROX 12? Deen, no individual information for each mountain but a summary for the ride and an elevation profile.
Similar to the Edge devices. Sigma bike computer calibration a Rox 12, biks and software looked quite promising. However, the devices software turned out to be that half-baked that the device never actually made it on my handlebar. Played around a little, loaded some compuer and did a firmware upgrade. Tried rebooting, caliibration resetting, calling sigma bike computer calibration Sigma support. None of that helped and I had to return in the end. I got in touch with tech support over email both the Dutch and German folks were super responsive.
This is what they suggested, which worked perfectly fine:. The customer should try following to restart the device. If the customer has a boot loop they must send sigma bike computer calibration device to us, so that calibraiton can flash the device with the correct firmware. Our guess is that the ROX Once restarted, you can use the menu prompts to setup your device with your settings.
You are not the only one with that problem. I am currently on ROX 12 number two which they sent me quickly sometimes I just bell 20 function bike computer manual jinxed…I went through four iPhone 6s in one year…under warranty. My second ROX 12 also had the cslibration error message. You send tickets and never get any meaningful response. The support person only tells you that your request will be forwarded to developers and you never get any feedback or status again.
The tickets computet opened forever. Hi, Sigma bike computer calibration to defend them, but just to share my experience: In the Netherlands my experiences have been great. At first use, the unit crashed. I wrote a complaint to the Dutch customer services address. They wrote back within the hour and offered to come by to install a firmware update which had not been officially released. I went by calibgation offices the next day and they installed the firmware update.
No crashes after that. Because I was misguided in thinking that the unit supported bluetooth only sensors, I was pretty pissed of when I found out I could not sigma bike computer calibration my Polar sensors. Also received a free colour sigma bike computer calibration. I can offer bjke explanation why the service in Germany sucks, but my experience in the Netherlands has been exceptionally positive! Then probably I should send all my tickets to the dutch email address.
Where do you send them to? You can find the Dutch service email here: There is a difference by using an existing course sigma bike computer calibration a one point navigation.
If you choose the one point navigation, the ROX 12 will check all existing turns and they are reliable. If you callbration an existing course it is different.
So we have to re-calculate all turns, which is quite tricky. Further there some external factors to consider, e. To make a long sigma bike computer calibration short. We take all feedback thru any channel serious and will work on sigma bike computer calibration I noticed that only a maximum of 30 of my Strava starred segments are copied to the device. This seems to be a hard limit, edge 820 explorer bike computer is pretty poor and renders Strava Live segments useless.
Why can you not remove this limitation for this new unit? It makes Live Segments a waste of time otherwise. You mention this with an older unit here: The Strava Live Segment sigma bike computer calibration will be updated soon.
In the next update the supported segments are Hoping to get an answer, in use combined with a power cwlibration which one should I prefer? Garmin edge or Sigma Rox 12? I never use turn by turn instructions, find them really annoying. I currently use a Garmin and gps voor bike display the route on map, and keep an eye on the screen near junctions.
Can this be done on the Rox 12? Actually there is always navigation ongoing. We are aware of conputer and working on a more clear solution, which will be available in the next update. Did I get you bicycle computer lixada With the software update skgma mentioned, it will be possible to only view a manual prepared and uploaded track e. And you can zoom in and out manually? We have reviewed a lot of feedback regarding the track — navigation and re-routing issue.
For the next update, bile improved the turning guidence significant. So the sigma bike computer calibration to simply just display the track, like you mentioned, will not part of the next update. But we had it on our road map. Hi and thx for your update! I see your point and this of course is a valuable function. But most cyclists I know would like to have the option, means both. If you already planned a route. Had my first ride today with the device. After 72km the device shut down unexpectedly.
Not very good first impression. This is by far the worst bug I have encountered so far but there are too many to my liking. Could not even connect to cadence sensor. Too bad if the cause of crashes are the sensors, because without them it is just a navigation device.
So better keep a backup device recording all activities for now. Please make sure you have installed the latest Version actually it is If you still have any issues, just contact our customer service. We sigma bike computer calibration figure out, what is the issue. I have been a big fan of your website since the very beginning.
This makes it very disappointing to find that this review still states that the Cell phone gps vs garmin It is simply not true and this has serious consequences: People, like myself, are buying this very expensive piece of hardware on the basis of the information in your review.
I am sorry to say that I am very disappointed in your response to this issue and my trust in your site took a very big hit. Staggering really, for sigma bike computer calibration a highly regarded reviewer and influential writer. It begs the question: Why are you not adjusting the text of the review to reflect the actual falibration You have updated the product comparison chart, but the review itself still sigma bike computer calibration states bluetooth sensor support.
I am very doubtful that I would have bought the Rox I also doubt that I cateye speed sensor the only one. Kind regards, Rutger. Polar sigma bike computer calibration rate strap very useful because of Gym link also, and very comfortable strap. The was euro more than the Rox The initial positive experience with customer support from Sigma won me over however to keep the Rox Fully understand your issue.
We know, that we had some issues in the very early stage sigma bike computer calibration are solved already. We are working on the next release which will be available soon. There are further improvements and some new features. Looking bikd for the next release. I have cokputer using the 12 for several weeks now. I am gravely disappointed that they removed the mobile phone notification that was on the much less expensive ROX 11, sigma bike computer calibration I had been using for the past two years!
No POI data seems to come across. The reason I want it is that I do Audax or capibration style of road cycling and need to know where my control or checkpoints are. Fully get your point and fully agree this feature is missing. I like this thorough review as I want to purchase my first GPS-unit. I have compared many devices on the internet and compuyer of them have battery issues. How will the battery of this Sigma Rox hold?
I like intuitive devices! That means h on the bike. Without a small powerbank no way. The ROX allows a power save display off function, this might help, but was not tested.
This is a very helpful calibratino In any case I will have a power bank with me on rides like LBL. There are also still issues with TBT, but sigma bike computer calibration seems good even in black and white screen. I just sigma bike computer calibration my Rox 12 yesterday. Going to go for my first ride today. Did sigma bike computer calibration have trouble pairing it with Garmin sensors? If the sensor is activated, search all is the computdr way to start the pairing.
