A / The annoyances:
a) sensors and magnets
1 / they are indeed quite impressive, and it is all the more curious that the counter has a modest size in relation to the exercise of all functions.
2 / fixings, even if they are well thought out, not entirely satisfactory. I find that setting using the elastic is not sufficiently stress (sensors tend to move from their position of equilibrium). I wonder however, if these vibrations and changes in distance from the magnets do not generate the observed signal loss (admittedly minor but irritating).
3 / the magnet mounting system on the front wheel for speed keeps well, but I was able to start the system "claw" only one side of the cylindrical magnet. Finally, he still holds and that is the point.
4 / the magnet mounting system to lay on the handle must be tightened very strongly with the cable tie, otherwise the sensor will slide along the handle (due to the change in shape of the section thereof)
5 / sigma indicates that the elastic system allows quick removal of the sensors (interesting to prevent theft or transport), but the sensors including the meter base, are equipped with adhesive! So what do we do? For if the adhesive is used, I do not see the interest of elastic and dismantling that does not become easier. Also, that probably does not help that the vibrations associated with this elastic system because I left the film adhesives can disassemble quickly.
6 / The meter displays the heart rate when mounted on its support. It's a shame, because I'm going to have to buy a watch, unless always stay beside the bike. The support with USB does not show the pulses. It's simple, I thought the service was out of order, I even changed the battery of the belt. All this must be a logic-saving batteries. Blah blah.
b) the counter itself.
So there's friends is a long poem, I try to make it short. I think (in my case) that my iphone took me by the hand too, because with this counter must be reset my brain the way, and in the month of August is not easy. In fact, no touch in this case, but not less than 5 buttons, and sometimes combinations of buttons! For example, to set the current altitude must be pressed simultaneously on the up and down buttons to the right of the counter for two seconds ... It is not intuitive at all, and thus a passage through the instructions is mandatory ... Now it is I find in overzealous not a very easy access. Unless I have not usually read the manuals either ... It might be that. Anyway, after a hassle that I experienced, staining to operate the quick counter after reading the leaflet, and some vacuum tests, I warmly invite you to understand how your device before putting on your bike. Otherwise, you will scream, you might like me to appear, "you want to clear all data?" Without opportunity to say no! In fact it deletes the data from the start of your bike out but not recording Loading ... Finally, it's been bitching anyway!
It must go through the manual box, to understand that you can make it display anything you want, or almost.
c) the counter display
well, it is clear, I quibble, and perhaps I'm wrong, but are 5 basic meter indications that you can not change in the selection display (maximum display mode data). Altitude, heart rate, the frequency of rotation of the pedals, and the slope in% of the road in addition to the wholesale rate in the middle. All these values are the instantaneous values.
To these values we can add another (from a choice of 60 it seems ...)
B / Positives
1) sensors and magnets
They are of a quality that is really fun to see. For the sensor attached to the crank, I did not hesitate to shoot the Rilsan with forceps without fear of breaking the sensor!
An interesting option is to buy a complete sensor kit for a second bike. What I did (not available on amazon, we must seek in Germany). The advantage? More still retain the same counter, are grouped in the same software, the outputs they are made with the bike 1 or bike 2. all for about 40 euros!
2) the counter
such as magnets, it is a perceived quality that gives pleasure, I find it a bit small, but it has the advantage of this flaw, you can slip it into his shirt. I must check the seal because some users are complaining.
3) the functions
say, that apart from gps, my iPhone 3G can still do with garmin made application that runs on old iOS, Sigma rox 9.1 does it all! Most importantly, it offers two profiles that can be programmed 2x10 functions before you leave. Heart rate zone, speed ascentionnelle and even calculated power available in the middle of dozens of other applications. It's amazing! This is why the user manual must be mastered. For it may be that your favorite feature is not recorded in the 20 pre departure. This function can be added to the base 5 that display of authority.
4) memory and records
When you start, think to trigger the recording paper (2 seconds on the main button). The meter will register all the functions available to restore them into the sigma center software. Great news. I forgot once to launch the newspaper, but the counter has registered still the main functions and was able to return them in sigma center. There, I say bravo sigma. You have to think stop recording on your return (ditto commissioned).
5) the software sigma data center
The CD included version 2.0, and easily obtained on the website, version 3.1 for free. I myself have an iMac, the software installs and above functioned properly. Be patient for installation on Mac winded like mine, remain calm and wait as all goes well.
This software is a killer with his companion rox 9.1.
Indeed, as you set initially, the bike weight, the web, the width of your shoulders, your age the maximum heart beat; you get back excessively complete information. I do not have the courage to list them all, but I will mention those that I use a lot. The instantaneous power coupled graphically road conditions, average power, calories burned, past times as a pie in heart areas / zones effort intensity, the total ascent amount, the pedal rotation frequency means. But there are many others that can be displayed on a graph. It was amazing!
In addition, the software remembers your previous outings, so that in a glance, you can compare your feelings with the raw values. It seems that a comparison function is available (I do not have enough outputs to test).
The software can plot histograms stick months per month.
It's my ultimate meaning of the refund level. Especially since you can print, save as picture format (pdf).
C / Conclusion
I must say that I do not clung very important when shopping for the operation of a meter data. In the case of this sigma rox9.1, if I find the complete software and especially if successful (can extract the last run even if we forget the outbreak of the newspaper with the data), that I withdraw any stars for sensors were they originally (still to be validated) two or three transmission losses for 1 to 2 minutes. If I find the source, I will make an edition of my comment. After a run-in period 6/7 outputs will become an indispensable companion that I will duplicate on my second bike buying only the sensors, the counter knowing manage two different bikes (diameter wheel, etc.)
Thank you for having read this far ;-)
