Bicycle wheel magnet

thingiverse

I was feed up with the standard offerings of cycle computer magents so decided to create my own mount for rare earth magnets. My design is less likely to move as it uses strong magnets it is gives more reliable reading. You simply place the spoke into the mount and then slide the magnet into the top or bottom. It may be a bit tricky to slide the magnet as part of the design is for the magnet to wedge everything in place For this build you will need a 3.8x 3.8 x 12 mm magnet. Available for a few pennies on eBay from many sellers.
