Specifications

Upgrade Your Bike's Performance with the Shimano 105 RD-R7100 12-Speed Rear Derailleur - the Ultimate in Precision, Durability, and Style

The Shimano 105 RD-R7100 Rear Derailleur is engineered for serious cyclists seeking reliable, smooth shifting in all riding conditions. Built with innovative technology and premium materials, this 12-speed derailleur offers superior performance, enhanced compatibility, and a sleek, low-profile design that complements modern bicycle frames.

Materials & Engineering Excellence

Constructed from lightweight, durable aluminum and high-strength steel components, the Shimano 105 RD-R7100 ensures longevity and excellent power transfer. Its Shadow RD low-profile design reduces cross-chaining and minimizes interference with the chainstay, making it ideal for aggressive riding and technical terrain.

Performance & Technology

Featuring dedicated Shimano technology, the RD-R7100 offers precise, stable shifting with a total capacity of 41T, accommodating large cassettes up to 36T for versatile gearing options. Its single tension construction prevents derailleur hitting the chainstay, providing extra clearance and reliability during rough rides. Compatible with HG 12-speed chains, this derailleur delivers smooth, silent gear changes across a wide gear range, making it suitable for both endurance rides and competitive racing.

Components & Compatibility

Designed specifically for Shimano 12-speed road drivetrains, the RD-R7100 features a 10x1 standard mount with Shimano's Direct Mount compatibility, optimizing fitment on large, contemporary frames with oversized chainstays, particularly mountain bikes with thru-axle dropouts. The medium cage length ensures optimal chain wrap and stability, enhancing overall drivetrain performance.

Style & Use Case

With its sleek black finish and low-profile silhouette, the Shimano 105 RD-R7100 seamlessly integrates into high-performance road, gravel, and mountain bikes. Whether you're conquering mountain trails, tackling long-distance adventure rides, or upgrading your road bike, this rear derailleur delivers consistent, clean shifting that will elevate your cycling experience.
