Excellent solution for combo brake/shift assemblies

My Schwinn has the combo brake / shift assemblies and I needed a solution. This assembly worked perfectly with a little epoxy to hold the magnet on the brake lever, then carefully placing the sensor with the high strength tape on the bottom of the assembly. No modification whatsoever to the assembly.

Sensors work great, but can be a real pain to install.

I have nice disk brakes on my bike and obviously wanted to continue using them. I bought these sensors, and they do indeed work great when installed, but can be a real pain to get mounted properly and securely. I have Avid Elixir RSL disk brakes, which have a round body and levers which made it nearly impossible to use the provided adhesive strips. This is likely the case with most end users since most brakes just don't have uniform flat surfaces where you would need them. Many users have mentioned using epoxy and such, but I decided to design and 3D print simple brackets that snapped onto the brake body and lever. Regardless, you will likely spend a few hours getting these things mounted, and they might not look too pretty in the end.

Just to be clear, I would not entirely fault Luna for these shortcomings, it would be nearly impossible to design a sensor that could easily mount on all brakes, there are just to many different kinds. So it seems like they chose to provide a reasonably priced set of sensors that the end user must customize on their own.

However, I believe some of these problems could mitigated with a mounting kit of sorts for these. Perhaps you should include a few loops on the sensor body that could accommodate a few zip ties. This likely would have been enough to get these mounted on my round and tapered body brakes. Likewise, a little holder for the magnet, or even just a small flat surface, with a few zip tie loops that would facilitate easy mounting. Zip ties are never too pretty, but do often work fine for long term solutions(as long as you don't use Harbor Freight zip ties!). I'm sure something like this would incur additional cost, but a $10 kit of small injection molded plastic pieces and zip ties is probably worth it compared to a few hours of tinkering for many end users.
