The QO Race SL crankset weighs just 510g, including 50/34T chainrings, making it lighter than leading brands like Campagnolo, Shimano, or SRAM. The new crankset features a hollow carbon design and a 4-bolt spider, optimized for weight savings. Compared to the previous Race model, the Race SL is 112g lighter, achieved through a machined 7075 alloy spider and chainrings. These chainrings are designed with traditional cut-outs and aerodynamically shaped dimples, balancing weight reduction and drivetrain efficiency without resorting to smaller cassette cogs.
