"With the new Tiagra R4000, Shimano provided the modern performance roadies are looking for. Along with improved performance, it also hit the price points they wanted and saved about 200g along the way."
"New in this drivetrain group is an 11-36T, 11-speed cassette that boasts a 327% gear range. Paired with multiple chainring options, this Hyperglide cassette allows you to find the needed gear ratio for everything from stout sprints to steep climbs."
"Lighter and smoother front shifting is promised with the new front derailleur. The Tiagra 11-speed front derailleur features Shimano's toggle-link construction and an optimized cage design, delivering precise, natural shifting performance."
Shimano introduces the Tiagra R4000 Series, a new 2×11 mechanical road drivetrain designed for performance and affordability. The system features an 11-36T cassette with 327% gear range, offering versatile gearing for sprints and climbs. The crankset provides two chainring options (52-36T or 50-34T) with multiple crank lengths from 165-175mm. New front and rear derailleurs deliver lighter, smoother shifting with optimized cage design and toggle-link construction. The drivetrain maintains compatibility with existing HG-X11 chains while achieving approximately 200g weight reduction. This release marks the eventual discontinuation of the Tiagra 4700 10-speed drivetrain.
