Usually I can fix it with very simple tools, even out on the road.


I normally do all my own bike stuff. However twice this decade I have
had to get shift levers replaced. They seem impossible to me to fix.

So I can't really see that electronic is that big a change from where we
are now.

Sounds like "we" are in different places now. I'm betting that you, like most
"sport" cyclists, are using brifters - STI or similar.

I'm not using brifters for exactly the same reason I'm skeptical of electronics.
Some of my bikes have friction shifters, some have index bar-end levers or
index levers elsewhere on the handlebars. I'm sure I can disassemble any of
those if necessary - but it will probably never be necessary. They are very
simple devices, with little to go wrong.

BTW, my oldest index shifters are on a couple different three speed bikes. I've
had those apart. I don't exactly remember, but I'm guessing there were maybe
three moving parts. Heck, I could fabricate replacements for those!

Lets see how often did my brifters (ergo and STI) fail on me in the last 25 years...hmm....never. In take my chance for the coming years.
