After a good old fashioned crash because of jumping rear gears I think I am ready to make the move to an electronic shifter/derailleur.

Currently I have a 1x10 setup with internal routing in the frame and drop bars (and drop bar style brake/gear levers) with hydraulic brakes.

I don't want to throw money so will try to find something second hand. What options are good for a 10 speed rear electronic derailleur and a drop bar style brake/gear lever that will support hydralic brakes?

I mostly ride gravel trails and a little bit of road

Thanks!

    I would investigate the cause of the "jumping gears" rather than "switching to electronic". For example, the case of jumping not attributable to worn components were because I forgot to enable the clutch of the derailleur (in the two cases that would be the same with or without electronic shifting). Also, 1x10/hydraulic seems a strange combination to me (I'm aware of 2x10 hydraulic GRX400 or 1x10 mechanical - Advent X), but I'm not aware of the all products on the market.

  • Agree with @Renaud here. Chances are the skipping has nothing to do with the fact that your current shifter/derailleur combo is mechanical, and instead something else: worn chain, worn cassette, misaligned derailleur hanger, or some combination of all three. If, for example, the hanger is bent, putting a new derailleur (electronic or mechanical) on it will not fix the problem. Commented Nov 12, 2022 at 18:48

The only 10 speed electronic shifter's i'm aware of are Ultegra St-6770, however these are designed for cable operated brakes. They could probably be paired with a cable pulled hydraulic calliper such as the TRP HY/RD.

Overall i think this would be an expensive and not very advisable conversion to attempt.

  • the shifters can be any model, the derailleurs determine the number of speeds with Di2

  • Why is it relevant to find a 10-sp shifter? Unless I'm wrong, the derailleur will also need to be replaced, and the only electronic ones are 11-sp (GRX800) and 12-sp (SRAM), so that will require a new cassette and a new chain anyway (and a new chainring if SRAM).

  • I (perhaps mistakenly) assumed there would be a 10sp derailleur to match the 6770 shifter. If there is no such thing then the idea becomes even more expensive and even less advisable.

Thanks everyone and after some more investigation it seems like there are not any good and affordable 1x10 + hydraulic setups available.

The most affordable option would be SRAM Rival eTap shifters and derailleur and then a new chain and cassette.

I will start saving now!
