I want to install hydraulic disk brakes on my bicycle, however I also need shifters as shifters and brakes are integrated on my bike.

I have 3 speed tourney FD TY 500 triple in front and Altus MD310 rear derailleur in the back. Now I have trouble finding rear shifter, so can I use SL M310 Shifter with an RD 310 Derailleur?

    I assume you mean hydraulic disc brakes specifically, as hydraulic rim brakes are extremely uncommon. Is your frame built to accommodate disc brakes?

  • How many gears in the back do you have?

  • Just for completeness, your bike already has disk brakes? Checking that the frame has mounts for disk calipers, and the hubs have rotors.

Shimano 8 speed derailleurs and Shimano 8 speed shifters are always compatible. So yes, you can use the 8 speed M310 shifter with your 8 speed derailleur.

  • Is this the same with front derailleurs? Sep 9, 2020 at 6:32
  • No, not all Shimano 3x shifters are compatible with all 3x front derailleurs. However as far as I know they are compatible within the larger categorisation of MTB vs Road. So I suspect the Altus MTB shifter will work with the Tourney MTB front derailleur. (There is a lot less information available online related to cable pull for front derailleurs compared to information on rear derailleurs) Sep 9, 2020 at 6:49
