Take your cycling workouts to the next level with the Sigma Rox 9.0 triple wireless cycling computer, which tracks almost every workout detail you can imagine and then displays it in graphic form on your PC. The computer is equipped with a digitally encoded three-channel wireless Sigma Transmission System (STS), which allows the computer to use several sensors at once. This simultaneous sensing means the computer can measure your pulse, track your speed, and count your cadence all without missing a beat. The STS feature allows the Rox 9.0 to maximize your training data. 
The Rox 9.0's USB interface lets you transfer your training data to a PC for analysis. |
The Rox 9.0's speedometer functions include options for current speed, average speed, maximum speed, and trip distance. You can also compare your current and average speed on the same screen, or check the trip distance and total distance. The computer even offers a programmable trip section counter, a roadbook that lets you create a back-and-forth itinerary. The Rox 9.0's HR functions include ECG-precise measurements of your current, average, and maximum heart rate, along with three settable heart rate zones. Each zone has an acoustic zone alarm to notify you when you're exceeding or falling below your HR target. The display also shows your heart rate as a percentage of your maximum heart rate, along with your total calories burned and your total time in the heart rate zone. Serious cyclists can opt to use the computer's cadence functions (current, average, and maximum), which help you ride efficiently regardless of your destination. Adding to the computer's versatility are six altitude measurement functions, nine uphill functions, and eight downhill functions. The altitude functions cover the basics (current altitude and current incline/decline) in addition to more advanced calibration functions, such as calibrating your starting altitude and calibrating via the air pressure. The uphill and downhill functions use this data to create a summation of your training session, with such tidbits as the day's total climb and descent, the day's maximum altitude, the trip distance, the rate of ascent and descent, your maximum ascent and descent speed, your average incline and decline, and your maximum incline and decline. On top of all the other features, the Rox 9.0 includes a stopwatch, countdown timer, clock, alarm, three temperature functions, an LCD backlight, and a battery status display. The Rox 9.0 comes with a bracket for your bike handlebars and stem, and is adjustable to two wheel sizes. The computer also automatically recognizes a second bike, so you and a partner can train together using the same computer. And when you're done with your ride, the Rox 9.0's USB interface lets you transfer your training data to a Mac or PC. The information corresponds with Sigma's Data Center software, which lets you perform a comprehensive analysis of each training session. The Rox 9.0 requires a separately sold docking station to optimize the data transfer and analysis.

 Sigma ROX 9.0 - as good as it gets, July 15, 2009
By Spiko (NH, USA)
|
|
I have been using this computer for more than 3 months now and here are my observations.
PROS:
1) Overall a good value for the price paid , I think the combination of wireles monitoring of cadence,speed, HR and logging memory is unique in this price range. However, if you want a GPS capable computer then look elsewhere.
2) I like the customized view display and its layout, which is easy to read even during bumpy rides on unpaved roads.
2)The size of the computer is appropriate for its functionality and it is definitely smaller than corresponding Garmin 305 model.
3) I also like the fact that sensor batteries are standard types and can be changed by myself.
4) Accuracy of the computer is reasonable, I did not find more than 2% difference comparing the distance and elevation profiles registered by ROX with topological maps.
CONS:
1) I really don not understand why cadence is not part of logging memory. According to me, this is one of th top 3 parameters you want to monitor during a ride, together with speed and HR. It is quite ridiculous that Sigma is capable logging the air temperature but not the cadence. Was this designed for cyclists or meteorologists?
2) The sensor attachments are rather clumsy , which has been typical even for older Sigma models. Using o-ring combination with double-sticky foams is a cheap solution in this price range. Need to be frequently adjusted especially if you transport your bike in a car and take the bike wheels off.
3) This computer can be used only when attached to the bike base. Once you use it standalone, no HR can be recorded (elevation is the only variable monitored continuosly ) which makes it not usable for runners.
4) The elevation sensor is OK but since it is based on the air pressure (no GPS data calibration) it makes it very sensitive to the atmospheric pressure variation. I noticed that the elevation of my house registered by the computer varied by more than 20 m (60 ft) in a period of ~2 hours. So calibration before each ride is a must.
5) The uphill/donwhill grade measumeremnts are significantly time lagging and they show right values only if you remain at same slope at least for 15-20 s. It means that if you ride in a terrain with lots of short uphills and downhills, the computer will show +6% climb only after you passed the peak of the climb and are already on the downhill section.
Bottom line: It is a good cyclocomputer that reports all relevant variable that most people will need during rides. I find it usefull for improving my ride in terms of adjusting cadence and gear ratio to achieve optimum HR rate range and ability to log and compare my performance stats during short cycling season here in New England.

Good option for data, July 27, 2010
By Nathan Allen (Philadelphia, PA)
|
|
I've had the Rox 9.0 for several months now and it has worked well, I've been happy with my purchase. Here's the rational I used to pick it:
Non-GPS vs GPS: I primarily mountain bike, which causes problems for GPS systems due to terrain interference. Plus I have GPS on my smart phone that logs a map of my location, a second GPS is overkill. I like the accuracy of a wheel measurement of distance travelled.
Rox 9.0 vs 8.0 : the 9.0 can store more rides and it comes with the docking station, the price of the docking station is almost the difference in price between the two.
Topline 2209 vs. the Rox: The Topline can only store one ride's worth of data, I tend to get in a hurry and forget to download data to the computer after every ride. Both use the STS sensors. I initially bought the 2209 only to find out that the docking station wasn't available for it, making the download capabilities meaningless. Also, it's not that much cheaper that the Rox 9.0 when you take into account the cost of the docking station (if it ever become available, it doesn't work with the Rox station.)
Sigma vs Polar, Vetta models: Polar has a good HRM, but their speed sensors have been marginal in my experience (they've lost connection with the computer repeatedly.) The computer download methods Polar uses are laughable, sounds and IR transmission? Really? Neither worked even 25% of the time on my Polar 720i, which was top of their line when I bought it. Give me a metal to metal connection. Also the Sigma gives a heads up display of the grade of the hill I am riding, a nice bit of data.

 to complicated for a bike computer, April 24, 2009
By fer66nando (hawaii)
|
|
First at all is too big, I'm not to excited about the functions buttons,...I don't know, the advertisement is very promising but the computer it self not. The sensor are way to heavy and big, this company should compare with Polar, Shimano or other...overall I seriously thinking to return it...too bad, but I been involved to the road cycling sport for twenty two years and this computer makes no difference...great commercial but nothing more...

 a waste of money, April 19, 2009
By Scoot (houston, tx USA)
|
|
It's my fault for buying something so expensive that makes as many claims as it does. If it sounds too good to be true, it is. I know it, I know it, I know it. But I bought the Rox 9.0 anyway. A week later, the cadence meter still doesn't work. I've sent e-mails to Sigma only to be ignored. They got my money, they did their job. I'm out the money with out relief in sight.

Works great except when it is cold, February 17, 2010
By N. Marolf (Los Angeles)
|
|
I've had the Rox 9.0 for about a year now and in December when I started up my morning training regimen, I noticed it worked sporadically. I eventually figured out that when it is below about 50F, the 3-volt battery just doesn't produce enough power to run the head unit.
So, buy this unit if you don't think you will ever ride in colder weather - at elevation or on cool days in the fall/winter. Otherwise, you might want to look into something else. I really enjoy the features and layout of the Rox, but when it doesn't work, features don't really matter.
And, yes, the battery is fine, I measured it with my multimeter and it doesn't need to be replaced. The battery works fine on warm days in the sun. Sigma would do well to increase the battery power to properly run all the functions.
Oh, and I've waited 3 weeks for a response from customer service - haven't heard anything after two emails.

Make a different purchase, July 7, 2009
By J. Carothers
|
|
This computer has many advanced features as anyone wanting one knows. But it fails in a basic measure of usability, and this problem isn't confined to this top-of-the-line model: reset on this puppy sucks.
It stays on for at least a week after the last ride (no auto-off), and I still haven't figured out the magic of how to reset it for another ride. WHen I go through the reset values queries, it then fails to register the new ride. It may reflect some data, but not all (including heart rate). I can't figure out why it suddenly starts to read new dat during a ride. And speaking of heart rate, it doesn't indicate when there is a failure to pick up a signal, it just stops changing the last data point. No pulsing heart vs. still heart icon - nothing.
In short, another brand is probably going to bring you greater satisfaction.

 Sigma ROX 9.0: a quality cyclocomputer, September 30, 2010
By John R. Hargrove
|
|
I have used the Sigma ROX 9.0 on my road bike for about fifty hours, and I can say without qualification that it has exceeded my expectations and I highly recommend it.
Before making this purchase, I tried units from Blackburn and Polar; they worked sporadically or not at all, so I returned them. I was looking to replace my Shimano Flight Deck unit, which worked well but does not have heartrate or cadence functionality. I wanted to try the Garmin 500, but the price difference ( about $160.00) between it and the Sigma made it less attractive. After looking over the product documentation and the interactive demo on the Sigma website ([...]), I ordered the Sigma ROX 9.0.
The package includes everything necessary to install and use the computer: a printed manual, a page of installation instructions, batteries, O-rings and zip-lock ties, the sensors, the chest belt,the docking station, PC/Mac software on CD, and the computer itself.
Installation took about fifteen minutes and was straight-forward. The heart rate and cadence sensors synched immediately; I had a little difficulty with the speed sensor. I called Sigma tech support for help. I got through right away and spoke with a qualified support person; he helped me to troubleshoot the problem. When it appeared that the sensor may have been defective, he arranged immediately for a replacement part to be sent out, no questions asked. I got it to work later that afternoon and it has worked ever since.
I have enjoyed using it on every ride since; it has definitely enhanced my riding experience and helped me to evaluate my fitness. All three sensors synch up after I attach the chest belt, mount the bike and roll off. I have never experienced a signal loss or spurious signal from any of the sensors, even in the vicinity of high-tension. The display characters are large enough for me to see despite my failing vision; the buttons are conveniently sized and positioned.
It measures more than 40 parameters involving time, temperature, speed, distance, altitude, heart rate, and cadence. Having read both the Garmin 500 and Sigma manuals, I believe the functionality of both units is almost identical. I particularly like Sigma's Favorites feature, which allows the user to select two groups of any ten parameters and then display them with the touch of a button while on the bike. Navigating through the menu screens takes some getting used to at first, but becomes second nature. Using the docking station, the data center software and your computer, you can download your ride data and evaluate it as well as program the bike computer itself.
The quality of the components--computer, chest belt, and sensor--are apparent; there is nothing inferior about the fit and finish. The warranty covers product replacement, with proof of purchase, for five years.
If you are considering a Garmin or other high-end bike computer, I urge you to consider the Sigma ROX 9.0 before you make your purchase.

Great product with lots of info and horrible instruction packet, November 20, 2009
By Exercising on Insulin (Getzville, New York)
|
|
Once I finally figured out how to use the computer and softwear I love it. The instructional packet really didn't walk you along the complicated (at first) functions of the unit. The wireless HR monitor does periodically drop a signal. The unit came with "rubber-bands" to secure the units to the bike which makes it nice to move from road bike to tri bike.

 Good for warm weather only!, October 13, 2010
By Harry
|
|
I bought this meter about 2 months ago. My take on this computer is as follows
+ Customization of the display
+ Easy installation
+ Heart rate monitor is very accurate (compared simultaneously with polar cs300)
+ Datacenter Analysis tool
- Only records average cadence for entire trip
- Cadence sensor stopped working about month later (200 miles approx.)
- Stopped working completely when temp is under 60F. As I live in northeast, this computer is completely useless in Fall-winter. No response from Customer Service either.
Overall disappointed with this computer. Absolutely do not buy this computer if you plan to ride in temp under 60F degress.

Great product, poor documentation, June 25, 2009
By A. Lichten (Easton, PA USA)
|
|
The features of this unit are great. I love the flexibility of selecting which of the many pieces of data are available with only one button push. The setup was fairly simple, too. However, the documentation is confusing, and the software for downloading the data is, too.

Sigma ROX 9 Review - excelent option, June 23, 2009
By Edwin (El Salvador)
|

Sigma ROX 9.0 Triple Wireless Computer
It's an excelent cycle computer, but the product manual needs to be refined, there are some things that are dificult to understand, like what to do when the heart rate monitor stops sending signal, or how to calibrate de altimeter and when to do it, but the customer support of sigma it's excelent in order to resolve any doubt

Returned this item., September 4, 2011
By Jeff Leavitt
|
|
I had a previous Sigma device that was just bullet proof. Over five years worth. On the strength of that experience I bought the Rox 9 in spite of some not so stellar reviews.
Sigma customer service is excellent. Several phone calls and sent the unit back for replacement and it quit again. Returned the Rox 9 to Amazon and bought the 2209. 2209 hasn't skipped a beat. Missing a couple of features that the Rox had, but, not the frustration.

Great computer, can't beat the price, May 24, 2011
By jameskyle (Los Angeles, CA)
|
|
I've owned my Rox 9.0 for two years now (since 2009). It's worked like a champ. Just a few notes on some quirks:
-- The sensors require fairly precise spacing. You have to make sure the magnet and sensor are coming close enough or it won't be detected
-- If you're sure they're close enough and still aren't detected, it may be time to change the battery...even if the read out says the battery is ok. Mine would go out a couple of days before the computer would detect a need for replacement.
Also, after ~10k miles of use the bike mount contacts wore through. It ceased to retain a consistent contact for the computer and it would intermittently go out. Took me a while to figure out what was going on, but on close inspection you can actually see the plastic through the worn out hole. Fortunately, the mount (and any other auxiliary component) is replaceable for cheap. ~8 dollars on Amazon, shipped.
The above is only confusing if you haven't faced it before and other than those (minor) caveats the reliability of the unit has been rock solid for me.
I saw some reviewers commenting on poor performance in colder temps. I haven't seen this myself. I'm on the West coast (Los Angeles), so no extreme colds here. But it's not uncommon for it to get down in the low 40's, upper 30's. I also bike at altitudes and down by the beach with ample humidity and misting...particularly when foggy and haven't had any issues.
I give this guy a 5 star because, from what I've found, you just can't beat the reliability and features at this price point. That puts the Rox into a class of its own in my book.

Warm weather computer, May 9, 2011
By Aeolian
|

The other reviews are correct. Below 60F it may or may not work. If you keep it warm and start a log it will ususlly record all the information even if the display goes blank. Above 60F it works great

Great value for the price!, March 11, 2011
By christinechiang28
|
|
I love charts and graphs and the fact that the Rox 9.0 can spit out data like no other, makes it a great product. I've shopped around for similar equipment but this is the best value out there. The docking station is easy to use and downloading data is as easy as pie. Mm, pie. Oh, and vendor is great-- I called with lots of questions and he was very helpful and prompt with answers.

Sigma ROX9, November 15, 2010
By Gaurav (BOSTON, MA, US)
|
|
On ordering and opening the product I have the following observations
Instruction Manual should be clearer for 1st time users.
Otherwise set-up is straightforward
On performance its very accurate and the software is easy to use and helpful for your to improve
one suggestion is to keep the next version with a USB dock to make interfacing even easier
overall 4/5 rating

Not user friendly - question quality, January 24, 2012
By Skiper001
|
|
I bought this unit and ask my local bicycle shop installed for me.
1. Heart monitor never work.
2. It has difficult user interface, all the buttons don't seem logical - it is hard to reset and get to the screen you want.
I'm not happy with this unit and switch to Wahoo sync with my iPhone.
