ZRACE RX2 Crankset Features and Specifications
High-precision CNC machining creates perfectly aligned chainrings with minimal runout and consistent tooth profiles for smooth, reliable shifting under load. The ultra-strong alloy shaft resists deformation during high-wattage efforts, maintaining the rigid pedal platform essential for sustained power output on climbs and sprints. Gear options span 50-34T for aggressive gravel climbing, 52-36T for mixed riding, and 53-39T for road racing applications, giving you one crankset that adapts to multiple bikes. Available in 165mm and 170mm lengths, the ZRACE RX2 suits road cyclists and gravel adventurers seeking quality components at reasonable cost. Direct compatibility with Shimano and SRAM groupsets ensures installation fits standard road and gravel frames without modification.
Why Road and Gravel Cyclists Upgrade to the ZRACE RX2 Crankset
The wide gear range addresses the modern gravel trend, letting you climb steep unpaved pitches without sacrificing top-end speed on pavement sections. Independent testing confirms the ultra-strong alloy shaft delivers measurable power transfer efficiency gains compared to budget alternatives, translating to faster climbing times over repeated efforts. CNC precision means predictable shifting performance even after hundreds of gear changes, reducing maintenance frequency and extending drivetrain life. The ZRACE RX2 eliminates the need to buy separate road and gravel cranksets, cutting total upgrade costs while maintaining high performance standards.

Very fast delivery. Securely packaged. The product looks high-quality and is lighter than my old crank. There are no assembly instructions, but it was very easy to install the crank.
