Input:
Question: Is this unit backlit?  Can I use it at night?
Document: I don&#8217;t use the HR training zone features or download training data to my PC. There&#8217;s more going on in this unit than is useful to me but I&#8217;m not a big geek about training data. Overall, I&#8217;m very happy with it.
Not only did he tell me (in an email) that you could put the speed sensor on the back for use on a trainer (which I was considering), but he attached PHOTOS of two options to do just that. The other question was prior to the unit arriving... It does NOT have a USB port on it, but you can buy a docking station (about 25 bucks here on Amazon), and it includes analysis software. Can't comment on that as of yet.
I had this unit for a week before returning it. Each time I used it, one of the wireless units would not connect. I had trouble with the heart rate sensor as well as the cadence sensor. It's extremely frustrating when you start to ride and have to stop every 30 seconds to try and get all 3 units connected. I think they should have also combined the speed and cadence sensors.
I needed a unit with HRM and it&#8217;s good to have HR and cadence always displayed. Installation and setup were pretty typical. Two magnet options are provided for the cadence feature, one is the common zip-tie to the pedal type and the other option is a button magnet that simply sticks to the back end of your pedal shaft (simple, clean & clever). You can change the battery on the HRM yourself.
Yeah, you're gonna want to throw that crap in the trash, and just download the PDF in your preferred language from Sigma. Notice I don't comment on the units performance? That's cause it does what it is supposed to do, with no problems WHATSOEVER. Align the sensors as instructed, wet the electrodes on the chest belt before use, then go ride your bike![...][...][...]
I bought the Sigma Rox 5.0 about 6 months ago, but not from Amazon.This is an awesome little cyclocomputer, which is easy to install and use. The functions need a little bit of getting used to- it took me a couple of rides. The data are recorded every 5 seconds, so that little is missed and it is very accurate (checked the speed and distance against a Garmin GPS).
For what I consider a fair price, you get a reliable computer, plus every sensor you need (other computers around the same price level are sold with no sensors, or just the speed sensor). The quality is great and you get a ton of useful functions, which are also quite easy to navigate. It includes a thermometer with has been crucial for me to learn how to dress for Coloradan winters.The installation is ridiculously easy. You can use zip ties, or the o-rings included.
I&#8217;ve owned/used a number of different Sigma models, Cateye, Trek and a Garmin 705 and the Rox 5.0 definitely best performs the 3-function cycle-computer mission. I got the Rox to replace a Sigma BC 1909 and still use the Garmin when I need the GPS features. The best feature of the Rox is the large (upsized from the 1909), easy to read display which uses different fonts for data and field labels to improve readability.
Easy to use, and very reliable.
Great product. Simple to use except for turning it off. Still haven't figured out how to do that. Works well.
