Anyone got one of these? I’ve got the cadence sensor and want a speed sensor mainly for use on the turbo.

How do you set the wheel size? I’ve looked at the online instructions and there’s no mention of it.

How easy is it to move from bike to bike?

Is there much lag between changing speed and it displaying on screen? My main (only?) gripe with the RFLKT is the lag when I accelerate or decelerate.
