Which wireless computers have the signal strength to allow me to attached the sensor to the back chainstay? As opposed to the fork? This way I can get stats while riding the trainer and my front wheel is idle.
Cateye double wireless for one. The sensor is made for the rear chainstay. It has cadence too.
Anything that’s under $100?
James:
It is here for $129. http://store.yahoo.com/phattire1/caccdowibico.html
But your LBS can probably pick one up for you for $159.00 plus tax 
I just bought the Cateye Double Wireless for $99 at www.fullcycles.com.
However, I just tried to mount it the other day and I’m not sure if I’m going to be able to keep it. There doesn’t seem to be enough clearance between the crank and the chainstay to accomodate the cadence magnet on my bike (Merckx Team SC). I need to see if I can slide the sensor even closer to the seat tube, where there is more room, but still have it be able to pick up the wheel magnet. Alternatively, maybe I can find a thinner magnet. Has anyone run into this problem? Can I use any old magnet? The one it comes with is really thick.
Dire–can you get a magnet in the indentation of the threaded hole where the pedals screw in, or will the pick-up be to tight? Can you flip the cadence pick up up in the air, or does that not work?
I was actually thinking about giving this business to Tom.
Dire wolf
I had the same problem with mine - I have carbon cranks and there was simply no clearance for the supplied magnet
A solution that my LBS came up with - which worked great - was a flat, thin piece of self adhesive magnetic strip - which not only worked just fine - was paper thin - and did not damage my crank arm.
Simply stuck it on the inside of my crank arm - by the sensor and pedalled away
Good luck!
I took the magnet apart and tossed the little plastic casing. The actual magnet is stuck to the end of pedal spindle (in the crank arm hole for the pedal) and is flush with the inside face of the crankarm. My bike has really fat chainstays and I thought for a bit that I wouldn’t be able to use the sensor, but I got everything to work just fine.
Thanks, Pooks and Andrew. Two very elegant solutions.
Hey WTF? I said the same thing as Pooks!!! But no props!
And, last but not least, extra special props to Slowtwitch all-star mechanic Monk for his creative solution!
(I knew all those posts about converting from 9 to 10 were just a ruse. You’re probably laying up a carbon fiber frame in your garage.)
As a matter of fact, Bunnyman and I are working on an all carbon tire as we speak.
Anyway–if you can’t make that Cateye work for you, PM me, I will pay you what you paid.
Is there enough room between my crank arma dn chain stay to support the Cateye double wireless?

Did that work?
James–that worked about as well as anything other pic you try to post. would you like a step by step on pic posting? PM me.
Lousy picture, but can you get the idea. I will have to see how it goes together with the Zipp 808 on the back WHICH IS COMING TOMORROW!
I have an Apple iMac so all bets are off when instructed how to post pictures. I’ll try to shape this post up at work today.
Danke.
Is this a viable option for cadence sensor placement? As the crank passes it?
