Recommendations for cordless computer?rmlee

I'm in need of a cordless computer for my road bike and am interested in any suggestions. Here's my situation - I am planning on using my bike for triathlons, but I don't want to have to leave the aerobars on there all the time. The only problem is that I can't mount a normal computer on the bars without getting in the way of the aerobar clamps. My idea is to have a wireless mount that I could move between the bars and the aerobars, depending on what I'm doing. It would be great if I could find something with a cadence function, but that's not a necessity. I originally thought the wireless FlightDeck setup would work (plus it has the virtual cadence function), but then I realized I would still need to run wires to the STI levers, so that won't work.

Any suggestions?

As a FlightDeck owner, I'd suggest it is a bit over rated. It costs something like $100-150 for the full wireless setup since they nickle and dime you on all the parts you actually need. I'm always swapping cassettes, so my cadence feature is virtually useless anyway (I don't take the time to change the settings, or I forget). The Deck eats batteries like nothing I've ever seen.

Here is a radical idea. Buy a Polar S720i. It is expensive, but it will give you cadence and everything. You can do the double strap setup (rather then using the mount) and put it anywhere you want... or even wear it... esp. if you are training for tris.

Beware that your current ride data will be lost if you are away from your bike for 5 minutes or more. This will happen in auto or manual start/stop mode. The new versions of the 20's (520, 720) fix this problem and allow 30 minutes of pause time.

Like I said: 702i... I have never had any problem with my setup- never lost any data. With manual, you can just set it up as a new exercise set anyway...

If you have the 720, that is the new unit which allows 30 minutes on pause before resetting your current ride data to zero. It is the older 510 and 710 which will, on auto or manual, once paused, after 5 minutes resets the current ride data to zero. Your total time and heartrate info will be saved to the F5 file but your trip dist, avg speed and others will be zero upon restarting.

S710i doesn't have the resetting problem eitherSteve Young

I read the posts yesterday with respect to the problems of pausing and restarting with some of the Polar recording models.

I just checked the manuals for the S710 (old one) which does reset after 5 minutes and the S710i (more recent) which will give you 30 minutes before resetting. I have the S710i and can honestly say that it has been excellent - it's pretty complex but once you get used to it it provides most of the functionality that you are ever going to need.

It also (in non-biking mode) has a beep facility which alerts you to your heartrate if you are outside the pre-set limits. This doesn't work in the bike mode but is very helpful (for me at least) when running. I believe this feature is not present on all models.

Anyway, I don't think that S710i is necessarily still made although I may be wrong - however it should be possible to identify a supplier who has some old stock. If you can - this is an excellent computer that comes at a reduced (relative to the S720i) price.

Having said that, it's still a lot more than a wireless flightdeck so we might have drifted too far away from the original question.

I agree these are great units that give the user a wealth of info once you are familiar with the functions. The 510 has the beep warning outside of limits in normal or bike mode and works wonderfully. This is why I am so upset about the 5 minute reset problem. If I had the i version, which is obviously the fix, I would be a happy camper. To get back to the subject, you can get some 9.00 computers that will do a better job recording ride data (only) than the initial 520 and 720's.

S710i lack of warning beep in biking mode is my only complaintSteve Young

To get back to the subject, you can get some 25.00 wireless computers that will do a better job recording ride data (only) than the initial 520 and 720's. Of course the mounting problem would have to be addressed with two seperate mounts or one stem mounted model.

then there is the issue of cadence, which the original poster wanted.

Frankly, cadence isn't worth paying attention to after a few years of riding... you generally will have an idea.
Cadence is available (and maybe useful?) on S710iSteve Young

I've only been roadbiking since May so the novelty of Cadence readout might wear off. However I like to focus on this when I am on longer steady steeper hills as it gives me something to try and maintain. i.e. I use it as a target when hill training.

Of course I may be weird :) but I find the cadence readout encourages me to keep the effort constant when the natural tendency is to back off.
