Do I want cadence on my computer?

[Becky]

Can you just mount the wireless speed transmitter on the rear wheel for use on the trainer?

Depends on the wireless computer. Some use low-powered analog signals that won't reach that far. Digital wireless computers generally have stronger signals and can be seatstay-mounted. Check the computer's specs to be sure.

My VDO has, according to the manual, a transmitting distance of something like 5 feet. An analog computer may only have a transmitting distance of ~20 inches.

Hope this helps!
