Computers - wireless woes(10 posts)

Computers - wireless woesMass Biker

Okay. So I got one of those nifty Sigma Sport (BC800?) bike computers with the wireless transmitter. Seemed like a very (aesthetically) clean solution, and the monitor/device itself was very intuitive to use and superior (in my opinion) to my old Cateye Enduro. It's now three weeks later, and the unreliability of this unit is really getting to me. The first monitor worked fine for a week, but then quit (but was cheerfully replaced by my LBS for a new one). The second monitor seemed to work just fine when the wheel was spun in a workstand, but on the road, it alternated between 5 and 50 mph and then stopped reading altogether (although the clock worked swimmingly). I have reverted back to the wired version of the BC800 (which appears to be holding up and performing to expectations). Any suggestions on how to coax the best performance out of these wireless computers? Is the best solution to stick with the wired world or should I seek solace in the arms of Cateye (or Avocet?). Thanks - MB

In my experience, wireless computers just aren't worth the hassle. I've only used a couple (one a Cateye) and had problems with them almost from the start. Based on your board name, I'm assuming you ride in MA and will run into some wet weather, which will only decrease the reliability of a wireless model. IMO, any minor aesthetic improvement isn't worth the trouble that seems to accompany wireless computers.

I have the Performance Axiom 8.0 wireless on four bikes and have never had any trouble with them. They retail for $49.99, but I have seen them on sale for as cheap as $29.99.

Anything wireless is susceptible to RF interference. That is most likely the cause of your problems. I'm using a wireless heart rate monitor that goes berserk every time I enter a particular section of town. Ironically it's near a large hospital!

Sorry you experienced less than satisfactory results from the computer. Mine's been fine since I got it half a year ago. Two things that can be weird with mine, though: 1) Occasionally, the max. spd. registers things like 80 or 57; inconsistently, though. Usually, it's spot on. 2) When I used to go into a local bike shop (fortunately, I despise the place and won't go into it again), my BC800 flipped out when standing still. From 24 to 83 to 13 to 25 to 72, etc. It's got to be some sort of really strong electricity field near the entrance (like a theft-detection system) that did it. Once I cleared the info, it was fine (after I'd left the shop).

I wanted a clean (wireless) setup on my TCR, and I'm quite happy with the 800. I've also recently gotten the Sigma Sport PC-14 heartrate monitor, and am using it with great success, entertainment, and motivation. For $69 from Colorado Cyclist, it's a STEAL! Does calorie consumption; has a cool "backlight" (the numbers/letters light in a cool, indiglo-like blue rather than just a backlight) which stays on as long as you're pressing the various buttons for various info, then goes out; has an alarm; comes with a handlebar mount; and has many other great features. If you're buying one, call Sigma for a better version of their instruction manual in English; they'll email it to you pronto! Their number is 888) 744-6277, and they've been very friendly and helpful.

Hey MassB: what'd you decide on for a new bike to replace/pair with the TCR?

Cheers,
Nige

I've used the VDO, same as the Performance, and neverhad a problem.
I have also used the Specialized, which has an identical tranmitter to the VDO and the Performance Axiom, and never had a problem.

I have heard of multiple problems with the Sigma and the Cat Eye.

Try a different wireless. Some are great.

I have always used the Cateye cordless 2. I have 3 on different bikes and have never had any problems rain or shine. They are very accurate and reliable. I have also experinced weird readings while riding past two different hospitals. The speedo either reads very high or drops to zero while riding past these two hospitals. I'm guessing it's some kind electromagnetic interference. CHEERS.

I have a Sports Instruments SI90HR wireless and it's never missed a beat. It's been in several rain storms and has been flawless. Very clean looking and easy to install. Highly recommend it. They're about $110 and include heart monitor. For more info go to the following url

I had numerous problems with my BC1200(?). I eventually sent everything back to SigmaSport with a stern but respectable letter. They returned the computer with a new wireless signal sender and a new wired mount (I had the computer on two bikes) claiming they were defective. Apparently so were the replacements.

Enough was enough...I have Cateye computers on my bikes now.

FWIW: I've had very few good experiences with computer in general. Wired and wireless. Something always seems to go wrong. Some my fault...some not. If I get two seasons out of a computer I think I'm doing good.

I have had a specialized Team wireless for almost a year now and I have had no problems at all with it. Maybe it's the brand you have?
