I have a Cycleops spinner for training, and thought I had the bright idea of buying a wireless cyclocomputer to use on that bike with the magnet and pick-up on the rear wheel so that it'd work on rides AND on the spinner.

However, I see that the maximum range is 39" on some and only 26" on the one I was most interested in. I doubt that'd be enough.

Anyone know of wireless cyclocomputers having good enough range to work off the back wheel?

Or, other ingenious solutions?

I see that Mavic makes a Trainer magnet, but I don't have the compatible cyclocomputer, and like this SportsInstruments better:

Any help is appreciated!

The Blackburn Neuro has rear mounted speed/cadence and HR. It isn't cheap because it uses a 2.4 GHz transmitter, but that eliminates crosstalk. I like mine a lot.

I could have written this myself - I have a Cycleops, also, and had the same idea a few weeks ago.

Unfortunately, my cheapo Pfizer DBLW won't reach that far, unless I mount it on my seat. I'll have to look into the Cycleops pick-up.

Just looked at the Cycleops computer/HRM setup. $300+ is way too rich for me.

The CatEye V2c has a rear-wheel pick-up. It's wireless.

Besides mounting the speed sensor on the rear triangle as close to the handlebars as you can (maybe on the seatstays?), some (like Polar's) can be set to a higher transmit power - it might just be enough. You could mount the unit on the top tube, though you'd probably have trouble reading it - not as big an issue IMHO for using it on a trainer.

I had a Sigma 1606L setup on the rear wheel and recently switched to a Blackburn Neuro 5.0 so I couild add HR, also on the rear wheel. The Sigma wasn't 'advertised' to work on the rear wheel, but I gave it a shot and the rear wheel setup worked on both the trainer and the road.

Wow! Yeah, Cycleops is on crack if they think they're going to sell many of those.
