    Speed sensor on chain stay of Specialized Allez

    Hello,

    I'm a first time poster and a new cyclist. I just got a Cateye Strada Cadence computer with a rear left chain stay speed sensor and crank-mount cadence sensor. My Specialized Allex Elite frame has rear chainstays that hug the wheel and then flare out. As I'm new to this, I don't know the name for this setup but it doesn't have the traditionaal consistent taper from bottom bracket to rear hub.

    The problem is that b/c of the closeness of the chain stay to the spokes, there isn't room for the speed sensor to be mounted to the inside of the chain stay. Am I overlooking something? Can the sensor be mounted "on top" of the chain stay or does the sensor line need to be vertical for it to pick up the magnet?

    Thanks for your help!

    you'll be fine if you mount the sensor on the top side or bottom side of the chainstay. the most important thing is to position the sensor at the right distance from the magnet.

    Having the choice between top side or bottom side of chainstay, I would choose the bottom side. So that if the sensor slides a little bit toward the spokes, it couldn't get caught there, break a few spokes, and, worse yet, lock up the wheel, just when you don't want this to happen...
