Shimano releases updated Tiagra R4000 groupset with better gears, lighter weight, and improved design, phasing out older model by 2027.

Shimano has launched the new Tiagra R4000 groupset, a 2x11-speed upgrade featuring improved ergonomics, a lighter weight, and a 11-36 cassette for better gearing versatility. The update includes redesigned shifters, a compact rear derailleur, and a refined crankset, with the older Tiagra 4700 series set to phase out in early 2027. The revamp signals a retreat from the CUES initiative, reaffirming Tiagra’s role as a performance-focused, affordable option for entry-level road cyclists.
