One of them wouldn't work out of the box. Put the old one back in and ordered a replacement. You don't really know what you're getting these days.
Those generic cadence/speed sensors? They cost $30 for two, compared to nearly $40 each for name brand units that are
either cadence
or speed. At that price I can put cadence on multiple bikes and if one fails, buy another pack.
