I have a 20-year-old Specialized Sequoia 24-speed road bike. When the groupset was last changed on it, the shop fitted a 3-cog chainset (50/39/30) and an 8-cog rear cassette (28/11), a Shimano Claris crankset and Sora FD 3503 front derailleur, a Shimano Tiagra RD 4400 rear derailleur, and Shimano Claris ST 2400 shifters.
The drivetrain is fine - still plenty of life in it. But I want to replace/upgrade the derailleurs. Not a massive upgrade, but something that will provide me with smoother shifting and minimise chainrub. And obviously they'd have to be compatible with those shifters. From what I can see, there seems to be a wide range of compatibility with Shimano components - but I want to be certain.
Can anyone suggest a set of derailleur replacements that would fit my current set up and requirements, please?
