Date Reviewed: November 11, 2011

Strengths:    All the needed features

Weaknesses:    Eating the battery very fast.
When no Herth rate signal it keeps showing last mesured value - showing 0 would be correct.
Fails to start showing hearth rate after signal has been gone.
Clock is always wrong.
Support is really bad.
No cadence logging.
Temperature logging not needed.


Bottom Line:   
Has used 5-6 batteries in one year. The LCD screen has stopped working properly after 15 months. The PC SW is a bit quirky. Looks like I have to buy a new computer.
Going from 20 degrees celcius indoor to 10 outdoor it takes 30 min for the temperature logging to be correct.

Strengths:    - Speed and HR are very consistent.
- A lot of features.
- Good Data center software... after updates!


Weaknesses:    Many small things make me rate this product average:
- Can't keep track of time - looses like 2 minutes pro day, making the simple WATCH-function a joke!
- Battery status is useless - always green, even when obvious low!
- Temp. feature isn't even close to measure right.
- Non existing costumer service - Really BAD!
- Can record MANY hours with LOG-function, but need to be synced after only 7 rides (no matter length), if you wan't your rides in Data Center.
- Expensive


Bottom Line:   
Ok product, but has some quite big mistakes.

Strengths:    Records most things that you need
Customizable display
Accurate
Great pc interface


Weaknesses:    Take about 8 hours to get completely used to using the computer (without reading the manual)

Bottom Line:   
Brilliant piece of kit this! Sigma pulled the rabbit out of the hat with the Rox. Quality is great and I have yet to experience a problem which hasnt been 100% due to me learning the workings of the little gadget. I very rarely go on rides where I need a GPS to tell me the way (plan you ride - ride your plan) and if I do, my smartphone does that and a ton more. I have yet to ride at night but the lighting function works great. Compared to my polar and suunto heart rate monitors the calorie counting function is accurate and there hasnt been any loss of signal while riding. Recommended I got mine on ebay for 147 including shipping - beat that garmin! The Sigma Sports Center software is brilliant and easy. I have had tons of fun analyzing my rides so far. There is also the ability to export data to various formats, compare rides - you name it. Spot on!

Strengths:    Intuitive menue navigation, amazing number of feature-rich functions (which are fully customizable), wireless transmission w/o signal loss, downloadable trip and log options for after-ride analysis, good software support, excellent customer service, reasonable price for a computer this versatile, neat unit demo feature on Sigma's web site (try befor you buy). Many other strengths too numerous to mention in this limited space.

Weaknesses:    Little things here and there, but nothing major at this time.

Bottom Line:   
Perfect computer for my purposes. Just downloaded the v2.0.2 software and can't wait try it out. Looks like Sigma upgraded quite a bit and addressed several of my "wish list" items.

This is my third ROX 9.0--the first was replaced by Sigma n/c because of a software glitch with the early models that made some of them lose 40 seconds each time they entered sleep mode. The second unit again was recently replaced because the mounting tabs on the bottom wore down. Again, n/c and excellent customer service. Turn around time in each instance was less than a week. Software allowed me to reload previous computer info and set-up data with no missed beats. Had to replace one cadence sensor after epic weekend of rainy riding, but cost was reasonable--hopefully an anomaly.

I have no need for GPS so all the other functions in addition to the basics (plus on-screen heart rate) were just what I was looking for. I have logged over 8,000 miles between two bikes with many saved trip and log data entries. As a race organizer, the log function has been great for mapping out course information (especially elevation and %grade) for the longest point to point race in Michigan (Le Tour de Mont Pleasant). Highly recommended for a do-all computer if GPS is not important to you. Once familiar with the operating logic, navigating the computer menue on and off the bike if very intuitive. Based on the performance of this unit, I bought a ROX 8.0 for my spouse.

Strengths:    Comprehensive set of data collection and display/analysis.

Weaknesses:    Lack of cadence logging; mounting brackets wear out and bc falls out of mount; have replaced 2 sensors so far; the Battery Status check in software is unreliable; units prone to moisture (only water resistent but expected better); lack of comprehensive technical specs (eg no mention in my documentation of Speed Sensors' green/red Bike I/II reset)

Bottom Line:   
The ROX9 is a great bc and value for money, when it works. Apart from the frustrating lack of cadence logging and the occasionally flaky Data Center 1.1b software (can't wait for 2.0). I've had to replace 1 x HRM, 1 x main unit because of disappearing LCD display possibly due to moisture, and 1 x Speed Sensor in about 8 months of use and 16,000kms riding.

Sigma Rox 9.0 Issues

Is anyone familiar with this computer? I have one and after a recent battery change it basically stopped functioning. It is on, but basically just displays the "sleep" screen of time.

Which computer? Sigma Rox 9.0 or Garmin Edge 500

I am debating between these two computers. I would like GPS tracking, I could use my Droid X, but I think it would be more of a pain in the long run, between killing the battery and what not, but I don't know. I think it would be cool just to see where I rode. But what do you do with the data after ... Read More »

Sigma Rox 8.0/9.0 altimeter question....

Do you have to enter your elevation before every ride? The manual says you have to enter it. Wouldn't it just do this on its own? I can understand entering your current elevation once, but after that I would think it just senses the changes. If I drive to PA from Ohio to go for a ride, I shouldn't h ... Read More »
