I am considering purchasing a Cateye Strada double wireless computer. REI has it for $55 as part of its Labor Day sale and the price is tempting.

Before I purchase it, I want to know whether the sensor will fit my 2010 Felt Speed 30. What is the minimum distance needed between the crank and the chainstay and between the chainstay and the spokes to fit the sensor? How should I measure the distances on my bicycle to determine if the sensor will fit?

Thanks.
