wireless comp/hr question(5 posts)

I was thinking of going with a wireless computer for my new bike and was wondering if there are issues with interference from other wireless comps when riding in a pack or from other sources (powerlines, etc). And along the same lines, is the OwnCode feature on the higher end Polar HRs (with a personalized signal from transmitter to watch) worth the extra money, or is it a rare occurance for signals to interfere with each other in a peloton? Thanks for the help.

No problems with the wireless, once and a while they will be subject to outside interference. The problems they have are with the radio communications from the team cars to the peloton as they can be overheard by other cyclist and they are subject to outside interference and a lot of times all they can hear is a bunch of cracking over the radio lines..
I heard this mentioned during a stage in the TDF during a tech talk...

I have had a Polar HRM, Accurex Plus model for 4-5 years now and have had trouble when going by sub-stations of the electrical variety and not the sandwhich.

The Accurex died this past May and I have been searching for a better HRM. Without fail I had to mail the thing back to Polar every 11-12 months for a new battery.

I have found my new HRM it is a Ciclosport CP 29. It uses a digital transmission and the info is stored in the chest strap so if there is interferance the it will be corrected and the watch will get the update. It has a THREE YEAR WARRANTY. You can change the battery yourself without voiding the warranty even though they claom the batteries are good for 6 years use of 1 hour per day. It is packed with functions. The only downside is it will not come to the US until late September and it doesn't look quite a cool as some of the Polar models. Check out and follow the links to the ciclo pulse and I think they call it the CP-12 but the US version will be the cp-29....same HRM. The only real way to see it is to click on their new digital transmission icon and watch the slide show.

But as far as riding next to others with wireless units, they work fine, right? And does a little interference simply stop you from seeing your speed for a bit or will it mess everything up for the rest of the ride (ie screw up total time/distance rode)?

The only problem I've ever had with my Vetta RT88 wireless is that a couple of times while descending I picked up a bunch of garbage numbers that indicated I was traveling at 200MPH, then it reset itself for the rest of the ride (I was riding solo). Once in a blue moon it will change functions without me pushing a button, but my old Cateye Mitty 3 did the same thing. Actually the only real advantage with a wireless is that you don't have a wire wrapped around your fork. The wireless need a battery for the transmitter so I don't think there is a weight advantage...I went to a wireless as I pulled out a wire out of the back of my Mitty 3 and got tired of fooling with the sensor mounted on the fork. I have a Mitty 3 mounted on my 2nd bike and I taped the sensor on with electric tape and I've never had a problem with the sensor since...when I get some extra money I'll probably go with Campy Ergo Brain10 then I will have all the bells and whistles to keep me happy for awhile..
