Garmin cadence and speed sensor DSC10 bike seat tube bracket

thingiverse

I love my Garmin Forerunner watch which I use on my bike for GPS and heart rate logging. I bought the Garmin DSC10 cadence and speed sensor, but it won't fit to the bike with the standard mounting brackets or position. From a google search it seems to be a common problem. I designed this bracket to mount on the bike seat tube, picking up a magnet mounted on the bike crank. This will measure cadence only. You can still get speed from the GPS data. In addition to this bracket, you will need a M5 bolt about 40mm long, some cable ties, a slim strip of rubber to go between bracket and the sensor, a Cateye SP-6 bracket or similar to fit your seat tube with a captive nut on one side only of the bracket (they come with many Cateye lights), and a little thread lock. Assemble as the pics, adjust the angle of the bracket to the sensor before tightening the cable ties, tighten up the Cateye clamp so the captive nut pulls the non captive nut side between the nut and the bracket, a dab of thread lock on the bolt, then go ride! I might re-design the bracket to be a little curvier and not such a muck trap at the top. I have uploaded a slightly improved version of the files that I actually printed my bracket from, but they should be good. I'd like to thank my friends at http://lab3dprint.ru in Moscow who helped me with the design and the 3D printing in exchange for chocolate brownies:-)
