<\/p>\n

Today, Shimano rolls out a new road drivetrain that focuses on performance and affordability. The Tiagra R4000 Series is a 2×11 mechanical drivetrain featuring a new cassette, an ergonomic lever design, and other new features.<\/p>\n

And while Shimano introduces this new system today, it\u2019ll say goodbye (eventually) to the Tiagra 4700<\/a> 10-speed drivetrain.<\/p>\n

Shimano Tiagra R4000 Details<\/h2>\n

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.<\/p>\n

Cassette (CS-RS400-11) and chain (CN-HG601-11)<\/strong><\/p>\n

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.<\/p>\n

If you have multiple new chains lying around from the pandemic days, don\u2019t worry, you can still use them. Shimano carried over the HG-X11 direction chain from previous drivetrains as it shifts consistently well and is durable thanks to Shimano\u2019s SIL-TEC treatment.<\/p>\n

Shimano offers two chainring pairings and multiple crank lengths for the new Tiagra crankset. First, the chainrings are offered in a 52-36T combo, or 50-34T. Then, the crank arms vary in length by 10mm, with 165, 170, 172.5, and 175mm offerings.<\/p>\n

Optimized and designed specifically for 2×11-speed road performance, the Tiagra rear derailleur delivers crisp, precise shifts. It is compact and lightweight, but more importantly, reliable for smooth shifting.<\/p>\n

Using the advanced ergonomics from their 105 Series levers<\/a>, Shimano built the new Tiagra levers from the ground up. The dual control levers provide consistent brake feel and crisp shifting. A redesigned lever position and bracket provide the comfort, control, and confidence needed on a long ride.\u00a0<\/p>\n
