When choosing a modern crankset, one key decision is between direct mount and 4-bolt spider configurations. Each system has its own advantages in terms of weight, stiffness, and modularity.
Direct mount chainrings eliminate the need for a separate spider, reducing weight and increasing stiffness. They also simplify maintenance and are often preferred in modern 1x and gravel setups.
Brands like QO have adopted direct mount designs across their range, including the QO-GRAVA and QO-RACE models, for clean aesthetics and efficient power transfer.
4-bolt cranksets remain a standard in many road groupsets due to their compatibility with a wide range of chainrings and traditional gearing setups. ROTOR continues to support both options through modular crank systems, allowing riders to swap between spiders and direct mounts based on discipline.
Carbon spiders also play a role here, offering a lightweight interface in hybrid setups. Ultimately, direct mount is lighter and stiffer; 4-bolt offers broader compatibility. Riders should choose based on drivetrain preference, intended terrain, and weight goals.
Compare direct mount vs 4-bolt cranksets and discover which offers better stiffness, weight savings, and drivetrain compatibility for modern cycling setups.
