>From: Jim Bronson >What you fail to mention is that the electronic system has the capability to eliminate the need for mecanical cables, which would be an increase in reliability from my standpoint. If it wasn't for cable stretch, we'd never have to fiddle with our derailleurs. >From: Jan Heine >The problem you describe is not inherent with cables, but inherent with indexing in the shift levers. Moving the indexing to the derailleurs would solve the problem. The cables could stretch all they want, but the indexing adjustment would not change. However, indexing in the derailleur also would mean that you could use any shift lever. And Shimano invented indexed shifting specifically to make you buy a group, including their shift levers (and freewheel). Then they combined freewheel and hub into a cassette hub, so you had to buy their hub, too. Then they combined their brake and shift levers, so you had to buy their brakes, too. Then they combined their cranks and BB, so you had to buy the set as well.

>The obvious solution is to forego indexed shifting altogether and use friction shifting. I employ it on my bikes, and I don't ever worry about cable stretch, nor do I fiddle with my derailleurs. And I can combine any components I want (Maxi-Car hubs with Shimano freewheel, Huret derailleur, Simplex shift levers, Mafac brakes - no problem at all on my PBP bike). >In addition, downtube shift levers give you a warning when the cable frays at the shift lever (where it usually frays) - the sharp ends poke your hands. (In case you ignore the warning, or the cable fails elsewhere, replacing a shifter cable in the field is easy with downtube shifters, too.) >Finally, downtube shifters let you move your hands around every time you shift, thus preventing hand pain and numbness on long rides. >Maybe, once all the problems with electronic shifting have been worked out, and the system works off my generator hub (I think Shimano is working on that, their latest generator hubs provide more power at low speeds to make this possible), I will consider it. Then I'd want voice activation, too. Just like I say on a tandem to warn my stoker: "Shift" and the new gear comes in. Based on my cadence, the system will know whether I want an upshift or downshift. >In the mean time, the old Alex Singer will have to do. >Jan Heine >Editor >Bicycle Quarterly >140 Lakeside Ave #C >Seattle WA 98122 >www.bikequarterly.com 2/2

Taking a hand off the bars to shift is a bad idea. Personally without indexing I can't be certain I'm fulling in a gear unless I can hear the drivetrain, so if its windy or there is a lot of traffic it could be clattering away and slip if I need to stand.

Why doesn't one of shimano's competitors introduce derailleur indexing?

>>1157383 derailleur indexing already exists, it was made by shitmano many years ago and it sucks

Kek, electrical shifting auto-indexes too.

>>1157383 >why not derailleur indexing Derailer indexing is like cold fusion, perpetual motion machines, or cars that get 100 miles to the gallon: the technology is simply too powerful for the current state of humanity and had to be suppressed by the people who run the deep state.

STIs\Ergos are a very complicated and expensive way of moving a chain from one sprocket to another. They offer a nice and convenient solution but at quite a cost. DT shifters require a little more effort, however they have very little cable friction to contend with. I prefer the simplicity over the convenience. I used to love STIs but now prefer the clean lines and simplicity of a widely spaced DT setup.

Is cable stretch really a thing? I have a 9 speed Deore that I've been riding for 3 years now without any maintenance other than randomly rotating the barrel adjuster at the shifter when it slips or doesn't shift.

>>1157454 That barrel shifter does actually compensate for the cable stretching, so yes, it is a thing!

>>1157454 All the stretch occurs within the first 500 km of riding. After that you are good until the cable strands start breaking.

Fuck's sake. People need to stop perpetuating the lie of "cable stretch".

so correct me if I'm wrong. If I have a 7 speed rear derailleur used for a Shimano Sti brifter, then I could just hook it up to any friction shifter of any form and have it still work?

>>1158025 In that case he's not terribly wrong. It's quite an advantage to be able to piece together a groupset without having to care about compatibility. While compatibility is not itself a huge issue, for anyone with spare derailleurs, it makes putting them on a project bike without too much care so much easier.

>>1157383 >>1157387 >>1157392 Pretty much everyone, from Shimano to Suntour to Simplex to Huret, tried indexing derailleurs from the late 70s to the early 90s. They generally sucked pretty hard, then Shimano SIS arrived with indexing shifters that Just Worked and indexing derailleurs went the way of the dodo.
See

>>1158032 Yeah, indexing in slick and convenient - I would never go back to friction shifting my go-fast road bike, nor would I on my gnarly mountain bike - but sometimes it's nice to just throw together a bike with parts lying around the garage without worrying about compatibility.

Friction shifting is ideal for beaters, especially dt friction shifters, since they can always be unfucked enough to use. For gotta go fast type bikes, indexing is very nice to have, its just a question of $
