I am going back to wired -- unless you guys have a suggestion.

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

I could have bragged about my top speeds and can back it with photographs! MPH 70.3, 52.5, 36.8 (flats), My wireless has been giving false max and even current speed. I was climbing this hill which I can never go over 13 mph and there I was accelerating to 22 on the steepest part of the climb and then went back to reality. I know someone with the Cateye double wireless who had max speeds of 80 mph and RPM's up to 210.

Maybe it's just New Mexico with Big Brother high tech weaponry experiments happening all the time.


Any brand that's worthwhile? You know the battery (and transmitter) is heavier than the wires I guess I'll just buy a Garmin. I have an old truck as well where the speedo broke and cost a lot to replace the speedo plus you have to deal with DMV. Will a GPS cyclocomputer actually work on a vehicle as well?

VDO might be more stable. Not sure, some VDO owners could jump in w/ their opinion.

i use my Garmin as a vehicle speedo when i'm comming home from races- as my truck has over sized tires.

i dont know how DMV legal it is... (and kind of a pain due to battery life) but its certainly more accurate than most factory installed ones (they are usually a bit high- gives the consumer a false sense of better fuel mileage)

as for bike comupters... i'd highly recommend the Garmin. no sensors, wheel magnets, wires, can be changed from bike to bike w/ no thought... records EVERYTHING... immensely programmable...


great gadget.

How does the Garmin record speed up a hill? My understanding is it uses GPS to calculate speed, but if you going up, your GPS location doesn't actually change. So.... Does it even work right when going up hill?

Yes, the Garmin will work in your car.

Don't trash our fine state. The Government is the least of our worries here.

The science is quite complicated on how the Garmin uses several different input to determine speed. Just, trust me it's accurate.

Thanks... Munky -- Not thrashing our fine state. We are very under rated for our contribution to high tech.

Off to Performance.. I have too much points there and I can get an ollder Garmin for lunch money.

When GPS triangulates your position, it also tracks your elevation and thus elevation change. Your actual path is recorded and the time your took to traverse it is as well thus giving your speed.

You might try replacing the batteries before doing anything too drastic.

+1 on the battery replacement. If you still have the same problem and are looking for a new wireless computer, try a Sigma model with the encoded transmitter. I ride under powerlines and have not experienced any problems with my Sigma wireless unit.

I bought my VDO last year and worked great. Close to the end of the season I moved it to the stem instead of the bar mount it came with, and now I can't get it to work. After a back and forth with the tech support in Germany, 30 bucks worth of batteries, it still doesn't work. I lost the old bar mount so I had to order a new one. It might be a line of sight thing. If it doesn't fix the problem I am switching to Polar.

I rode with the Cateye dbl wirless for a few years. No real complaints. It will show 210 for the cadence if you tend to hover with your pedals hoziontal (left foot in rear) while freewheeling. You foot (and sensor) are actually travelling back and forth past the pickup quick enough to seem as though you are pedaling at max cadence - 210.

Apart from that dropout, crosstalk, interference can all be issues.

I have my Garmin now. I waited for a few years. At first I thought it was a stupid extravagence when it first came out. Then I started hearing from a lot of people some really good stuff about it. When they offered the $75 rebate last fall I found the cheapest spot and used the rebate and got the setup for about $150.

OMFG - it is worth every single penny and then some.



Seriously.

Wireless will almost always be vulnerable to RF interference and give some weird readings sometimes.
Doesn't bother most of us.
If your anal about true readings 100% of the time then wired is better. Bragging rites?
Better make sure it is calibrated to an exact rollout distance then too.
I know mine is very, very accurate and I always get a chuckle after I roll away from someone on a downhill at say 43mph constant and they finally catch me on the flats when I wait and say they were doing 50 on that hill..

i like my double wireless. granted i had to get a different HRM cause my polar was getting interfered with and showing HR's of 250+. since i got a timex HRM ive had no problems with either unit at all. the cateye has been super reliable since the day i got it.

I have pretty good luck with Sigma stuff, usually if I notice a lot of problems the transmitter battery needs a replacin'.

I changed the batteries -- even put foil in the battery compartment of the transmitter (I worked with bluetooth for one of the companies in that consortium), so I think I know something about radios (not the super secret stuff though))

Granted mine is a cheapo one... I don't know how it affects the odometer readings as well. I told myself I'll never buy a Garmin but since the real barometer of success is your motor, using a cyclocomputer to help you measure progress is a good idea especially if it is in one unit. I just saw this co-workers unit, it is so sweet, cadence, HR. elevation, speed and mileage -- all in one place.

Otherwise I'll go with wired which is lighter. Also if you use tape as per sheldon, no unsightly zip ties.

They should use bluetooth though. Then one could write a java app and interface it with your phone. Then the possibilities are endless. HUD info on your glasses, voice feedback of your stats, even uploading the entire ride to a web service. RFD on the presta valves, so you know if you are loosing tire pressure.

What do I know. I just started using a 10 speed gruppo a week ago.

Wires mess up the look, adds weight, and affects the aero benefits of the fork. Nuff said?

I've been using the new Cateye V3 triple wireless with good luck. Setup is fairly easy. The original battery went dead in 2 weeks, but the new one seems to be working fine.

Getting used to the various settings takes time. The cadence display is in smaller numbers than the speed and heartrate which is tough on my poor old eyes. I'm still trying to figure out if there is a way to switch readout locations. I don't think there is.

You can switch it between 2 different bikes also. I'm trying to find a second set of sensors and a mount. So far no luck from Cateye or ModernBike (where I purchased it).

Only time will tell if I keep it. So far so good.

Seriously.
What model Garmin are you talking about? I'm interested as I am currently in the market for a wireless computer/maybe GPS and that sounds like a pretty good endorsement.

I have a Sigma double wireless and it's been fine thus far. I wanted the cadence without the wires and happy I went that route.

305. IMHO the 705 is too new. Garmin just seems to have buggy gear. Too buggy to buy it when it's new. 305 has been out long enough to (hopefully) troubleshoot out all of the bugs.
