The Shimano Tiagra FC-R4000 brings genuine road-groupset refinement to an accessible price point. This 2x11-speed double crankset uses Shimano's Hollowtech II two-piece construction — the same platform found across the 105, Ultegra and Dura-Ace families — delivering a stiff, direct power transfer that suits everything from endurance road builds to everyday commuters seeking reliable, long-term drivetrain performance.

Highlights

• Hollowtech II two-piece design: integrated spindle and crank arm construction reduces flex and transfers power cleanly under load.
• 50-34T compact gearing: versatile chainring combination for confident climbing and genuine road speed on flat terrain.
• 175 mm crank arm length: suits taller riders or those who prefer a longer pedalling lever for more torque at lower cadence.
• 110 mm BCD four-bolt spider: compatible with a wide range of aftermarket Shimano-standard compact chainrings.
• 43.5 mm chainline: matches the standard Shimano road 2x chainline for precise front shifting.
• Styled after higher-tier Shimano groupsets: the spider flows cleanly into the outer chainring, giving a clean aesthetic on any road build.
• 2x11-speed system: full compatibility across the Shimano R4000 Tiagra groupset and all Shimano HG 11-speed road components.

Two-piece construction for real-world performance

Hollowtech II moves the outboard bearing position wider in the frame shell, stiffening the entire bottom bracket interface without adding weight. The result is a crank that responds directly when you accelerate, holds its line in a sprint, and stays quiet on long endurance days where a less rigid system would develop play over time.

Compact gearing for all-round riding

The 50-34T chainring combination is the go-to choice for riders who want genuine versatility. The 50T outer ring provides enough top-end for flat roads and descents, while the 34T inner ring opens up a usable range for sustained climbs — particularly valuable when paired with an 11-speed cassette offering up to an 11-34T range.

Compatibility & Fit

Designed for Shimano 2x11-speed road drivetrains. Compatible with all Shimano 11-speed road groupsets including Tiagra R4000, 105 R7000, and Ultegra R8000. Chainrings use a 110 mm BCD four-bolt pattern. Chainline is 43.5 mm. This listing is for the 175 mm crank arm length in a 50-34T configuration. Supplied without a bottom bracket — a Shimano Hollowtech II-compatible road bottom bracket (such as the SM-BBR60 for BSA threaded frames) is required. Supplied without chain guard.
