Electronic derailleurs

Post by flat tire » Apr 05 2020 12:51am

OK I am years late to the party here but electronic derailleurs are the best thing ever for a mid drive that uses the bicycle drivetrain. I just put a d1x trail actuator on my bike and it is SWEET.

Why?

You can pick any number of gears to use, for example a fraction of the cassette. You can set any position for any gear, meaning you can skip physical gears on the cassette.

My 11 speed cassette has 4 gears on the inside that are nonfunctional and for spacers only. Don't use them to start with. Of the remaining 7 gears I really only need 4.

I programmed this into the system and it works perfectly. Anyone else using electronic derailleur or other unusual shift system?

i think there are other threads but can't find them in a quick search.


then there's the n171 igh development kit, that had the autoshifting module and software. more than a few threads about those.

Cost, serviceability, points of failure, intercompatibility, potential for dereliction by the manufacturer.

Regular Bowden cable actuated derailleurs win on every one of these points, and they work very well. I’ve come across DI2 stuff in the bike shop, and my lasting impression is “meh, whatever”. Why not use engineering to solve problems that exist?

Does it need regular tuning or adjustment, or does it maintain alignment pretty well? I like the idea, but haven't had the opportunity to try one out.

this is a different solution approach. completely agnostic to any manufacturer. I was looking to use this same set up on my mountain bike for an upcoming continental divide mountain bike ride due to bad thumb UCL. after 80 miles a day in the saddle pushing a shift lever can be an issue. this has very light digital action.

Different approach, solves additional problems for others.

It holds alignment great so far and the process of positioning each gear is very easy using their app. It's easier to get a perfect tune than the usual method of setting the high and low screws. It remains to be seen how it does long term.

Yeah OK person on a budget with no imagination. Actually that's what these guys did and their solution is brilliant.

Yeah, I didn't know that engineering resources were limited, and that we had to ration them ?
