Introducing the ultimate upgrade for your ride — the 30mm Crankset System, engineered for peak performance and unmatched durability. Designed for both serious cyclists and weekend riders, this high-precision component delivers superior power transfer, reduced energy loss, and lightning-fast response with every pedal stroke.
Made from aerospace-grade aluminum alloy, the 30mm crankset is lightweight yet incredibly strong. It fits seamlessly into modern Boost-compatible frames and works perfectly with 1x or 2x drivetrains. The oversized 30mm spindle reduces deflection under load, ensuring rock-solid stiffness for aggressive climbing and sprinting.
Available in sleek black, silver, and stealth matte finishes, it’s not just about performance — it’s about style too. Weighing just 780g (for 170mm length), it strikes the perfect balance between low weight and maximum strength. The integrated direct-mount design eliminates extra bolts, streamlining installation and boosting long-term reliability.
Our 30mm bottom bracket features double-sealed cartridge bearings, offering excellent resistance against mud, water, and grit — ideal for all-weather riding. Compatible with a wide range of cranks and frames, it's the smart choice for MTB, gravel, and performance road builds.
Priced affordably without compromising quality, this system has earned rave reviews from cycling communities worldwide. Whether you're upgrading an older bike or building a new dream machine, the 30mm crankset is your ticket to a faster, smoother, more efficient ride. Don’t wait — transform your cycling experience today!
