A good question about electronic shifters

i was wondering , since we are entering the era of , e shifters , would one be able to buy an e - shifter and customize it to run any cog brand or gear range they have , since you can program them , i figured it would mean that now all cassettes or freewheels would be able to be used with a single , shifting system , as opposed to being force to match specific parts or hack drivetraines together **********???

I am sure that the manufacturers would do all that they could to prevent you doing that, planned obsolescence apparently being the linchpin of their business plans.

Nobody is being forced to match or hack anything.

That is a good question - and I wonder if maybe they already are compatible with different brands of the same speed. The differences are pretty small, and the feedback should align to the right place if the default isn't right on... right?

well certain parts dont work together , if you want to run different cogs on the same derailleur you have limits , . i was just thinking a programmable derailleur would allow you to load a profile and it would work , im sure it will happen eventually , i was just going to ask this as a reason to invest in an electronic system ....

Shimano,Sram or Campag do not have any system currently on the market that can do that. They all only work as 11spd. But they could easily implement true customisation into the existing systems if they wanted to.

This is currently in development.
XSHIFTER - Wireless Shifting System

https://www.kickstarter.com/projects...less-smart-shi

It does everything you describe but with a different approach. It converts any mechanical set up to wireless shifting. Instead of using seperate motors on each derailleur like Di2 or ETap. It only has 1 motorised unit that attaches to the frame. It still uses cables to the derailleurs albeit with a shorter length. So you can keep your existing parts. You then attach the shifter to your handlebars which sends each shift signal to the unit wirelessly.
The servo motor inside the unit then actuates and pulls and releases the cable. It can be programmed to be used with any number of gears front or rear via a phone app. And has features like auto trim and autoshift. Because the system is simple and can work with any 5,,8,,10,11,12spd drivetrain. It has alot of advantages over closed systems like Di2,EPS,Etap.

The question is, will the shifting performance be quite as good as above with direct motors? I think it will be close. The creater has a Youtube video with it hooked up to a micrometer and it operates very precisely.

I've seen a few Arduino hacks that could basically be told to do anything. So it'd be technically doable, but maybe not commercially.


The programming is one thing, building weather proof and rugged enough hardware is another.
I might be interested in something using already existing parts, but with an after-market controller.

The idea is no different than what companies like Cobb are doing for automobiles. They make an Accessport which allows you to load an off the shelf tune or have a tuner customize how the engine runs.

https://www.cobbtuning.com/products/...rt#accessports

There is absolutely no reason why someone can't develop software to do what the OP wants but remember that it software is limited by hardware. Software can't make hardware do that which it is not capable of. Samsung proved that.

Completely voids any hope of warranty service as well.
