I made this purchase because I wanted more information about my cycle rides than was being provided by my previous combination of heart rate moniter and basic computer. in addition to basic functions, I was really interested in generating elevation profiles of my rides, and getting information about inclines. I had no previous knowledge or experience of Sigma products - the Rox 9.0 was a recommendation on an online forum. In this review I'll say a bit about the unit and setting it up, the heartrate functions, the user friendliness of the computer, and the software.First of all, the unit which attaches to the bike is about half the size of a mobile phone. Certainly not cumbersome - I was surprised to read another reviewer complain about the size. The display shows three horizontal lines of information. The top line shows current heartrate, elevation, incline, and cadence. Helpfully, it is possible to zoom in on just one of these. If you are doing an interval and want to keep HR high then you can choose to have this shown in large size with the other values hidden. The second line shows current speed and an indication of whether this is above or below average for the trip. On the third line the user can scroll through a range of information including distance, trip time, average speed, total elevation etc. Setting up the unit was quite straightforward. I was pleasantly surprised that I had no trouble in getting signals from the speed, cadence, or heart rate sensors. The only time I have failed to pick up signals the problem was solved by wiping the back of the unit before reattaching it to the bike. The sensors can be attached by either O-rings or cable ties. I have used the unit on two bikes. On an old steel bike there was plenty of room to position the cadence sensor. However, on my carbon road bike with its chunkier stays it is a very tight fit indeed - the magnet on the crank almost rubs on the sensor.As for the heartrate functions, the first thing I have to say is that this is the best heartrate monitor I have used. Previous HR monitors have had problems with 1. Picking up a signal, and 2. Giving reliable readings. In particular I have been plagued by HR monitors which gave ridiculously high readings, particularly at the start of rides. Happily, the Sigma unit has been completely reliable and free of erratic readings. One of the most useful features of this computer is the ability to program in three heart rate zones. It is then possible to get information at the end of a ride (or during a ride) telling you how long you spent in each zone. This is great information if you are trying, for example, to spend a certain amount of time at high intensity. I have discovered that my long(ish) distance rides (say 80-120km) with plenty of hills have entailed much less high intensity riding than I had thought would have been the case.Overall, the unit is easy to read and understand. There is one thing to be aware of though. It seems that the computer must be removed from the bracket (the attachment to the bike) after rides. If not then the clock loses time, and data of the latest trip disappears.I am not a computer expert by any means. However, I found the software easy to install and use. Seeing rides that I have logged (not all rides are logged - this has to be done manually) as elevation profiles along with whatever other data I choose to display (speed, heartrate, incline, temperate etc.) has been a lot of fun!All in all I am a satisfied customer. This unit has given me all I wanted in terms of information about my cycling. The only features it doesn't have are GPS and a powermeter. But the former was not important to me, as I normally ride on roads I know. The latter was beyond my budget. Why four stars, not five? Well, I've used the unit for about a month now. It's durability is still untested. If two years from now it is working as it worked today, then my rating would go up to five. Time will tell.

This is a well made piece of kit. The HRM is excellent. It never fails to find your HR and only on a very very few occasions does it lose it but this is due to the chest belt slipping down. But once you get used to wearing it, it no longer becomes a problem. The HR is clearly displayed and is good that it has 3 zones which you can set. But this is where the excellent comments end.The computer would not keep time on or off the bike. It started losing about 6 then 20 minutes a day then went up to 3.5 hours which was real pain having to reset before each ride. On a turbo session of 40 minutes the clock would lose 6 minutes! Also on long rides this would affect all functions involving time. So I could not trust it and ended up using my basic trusty Cateye Mity 8 along side instead. However the HRM of the Rox continued to function fine. Well it appeared to.The cadence function is good, at least it was until after about 6-8 weeks the computer kept dropping the signal. I replaced all batteries but cadence would still drop to zero after about 10 seconds.Also the temperature readout seemed to be rather high. So I purchased another temperature device and found the Rox to be over reading.So having had enough I sent the computer back to Sigma, just the computer, not all the other gubbins to keep postage costs down. 3 weeks later I received a whole new replacement unit. I set this up and have not had any problems with the current unit. It picks up and holds cadence and most importantly keeps time, although I have to say that as I got the replacement at the end of the season in October I have not had much chance to use it as I don't use it on my everyday commuting bike but my road bike during club and training rides. I am hoping this unit is a little more reliable than the last one.In actually using the unit it is fairly intuitive. However I had to read the manual several times as it is complicated. There is little explanation or examples of how to use the functions in conjunction with each other or to set them merely map diagrams of what leads to what. In the end sitting with the computer over several evenings working through all the menus was the only way for me and I'm still not convinced I am using it to it's full as it contains a lot of functions! On the bike whilst riding it is fairly easy to navigate as you set up want you want in your favourites. On the road in a group you don't want to have to take your eyes off the road or what's in front to spend minutes looking down at the computer working on how to switch a function on or off!As for recording info for your ride in trips and log book this is fairly straight forward. You can create marker points whenever you want. Although you have to remember to download the log books otherwise once this is full (7 logs) then it starts to over write them. As for the soft ware analysis I have yet to use this as the previous computer's software would not install. But comments I have read on other forums is that it is very comprehensive. The only downside in that recording lots of data from your ride the computer cannot record CADENCE!!! This is a major drawback for me as cadence is something I like to know at any given point either when climbing or on the flat reaching HRmax or in each HRzone. So maybe Sigma introduce cadence recording as an update in future software.Overall this is a well made good bicycle computer with more functions than you could shake a sitck at, but let down by reliability issues of particular functions. Let's hope my replacement unit is more reliable. Time will tell. The customer service from Sigma was excellent in replacing my first unit after 9 months.
