RACEWORK GSR-RK2 Road Bike Crankset 170mm Double Chainring Aluminum Alloy

RACEWORK GSR-RK2 Road Bike Crankset Performance and Specifications

The RACEWORK GSR-RK2 combines durable aluminum alloy construction with a 170mm crank arm length optimized for road cycling biomechanics and power efficiency. Three chainring option configurations—50-34T, 52-36T, and 53-39T—let you select the gear range that matches your terrain and fitness level. The lightweight aluminum alloy frame minimizes rotating mass while maintaining structural rigidity, reducing fatigue during long rides and competitive events. Smooth crank rotation comes from precision-machined components and a sealed bearing assembly that resists contamination from road grit and moisture. The durable shaft design withstands repeated torque cycles, ensuring consistent performance across thousands of kilometers of road cycling.
