Hi,

I have a new time trial bike and am having trouble finding a suitable bike computer with a wireless rear chainstay mounted sensor (for winter indoor training) that works when mounting the computer on aero bars. Don't really need cadence, just speed and distance etc. Would prefer an all wireless setup for aesthetics.

Apparently the Cateye Strada wireless SHOULD work when mounted at the rear. However, it doesn't have enough ooomph to cope with the added distance when using aero bars (I know, I bought one).

I have read bad reviews on the Cateye wireless dual, so would rather stay away from that.

Can anyone recommend a reliable computer based on personal experience using a TT bike?

The VDO C3 DS supposedly is suitable for rear mounting, but again, I am wondering if it will work with aero bars.......does this company have a website?

Any help appreciated!

I have had no problems with my cat eye double wireless. I too was looking for something i could use on the indoor trainer which led me to the cat eye. The Mavic Wintech was the other one i was looking at but you have to purchace a separate piece( wintech digital home trainer). When everything is purchaced for this it is over $200.

<BUMP>

I currently have a Sigma BC 1606L DTS wireless + cadence with my road bike and was wondering what kind of wireless computers everyone here have for their tri-bike setup? I'm considering something with cadence/speed sans HRM b/c I have a Polar RS200.

Thanks!

I liked my Cateye double wireless a lot before I switched to the Garmin Edge. My only complaint was that it conflicted with my Polar HRM. My wife still uses the Cateye and she likes it.

What if you mounted it on the stem instead?

just speed and distance

mmm, if you are riding on a trainer, your speed is 0 and your distance is 0. You can IM for my address to send me half the money you just saved.

Seriously, speed and distance mean nothing on a trainer.

You have three variables you can measure that mean anything on a trainer, cadence, effort/power, and time. Time is easy, its on the wall, cadence is nice if you are trying to do some cadence drills, but effort/power is the big one and that is going to cost you, big time.

Speed and distance are calculated using the rotation of the rear wheel. I use rollers and not a trainer, but why wouldn't you be able to do the same thing on a trainer.

Tough to tell if you're trying to be funny or just being stupid. You do realize that a magnet on the rear wheel would give the OP a pretty good idea of how far he would have ridden if he weren't on a trainer, right?

I'm going to have to take stupid, because I wasn't trying to be funny.

Almost as stupid as trying to use distance and speed as indicators of training on a trainer.

Let's start with speed, what is the biggest impediment to speed, mmm, how about wind resistance? How much wind resistance do you have on trainer? Hmmmm. I guess thats not so accurate. But BV, my trainer has resistance or I can change gears and make it harder. Ok, at how many turns of a knob do you equate to your avg wind resistance when cycling. Ok, you can get back to me on that one.

So let's try distance. Since you don't know how fast your going, at least you would know how far you are going. And that means anything given you have no idea if you are working harder or easier than you would be on the road?

But oh stupid one, I get a good idea of how fast or far I am going. Any better estimate than time in the saddle? How would you know?

Time, Effort, Cadence. Anything else is just deluding yourself.
