Description

Elevate your ride with the E-THIRTEEN Helix Race DM 52/55 mm chainring, the ultimate fusion of ultralight performance, robust durability, and standout style for your mountain bike. Engineered for the discerning cyclist who demands excellence from every component, this chainring is designed to optimize your drivetrain for maximum efficiency and flawless reliability on the most demanding trails. Whether you´re running a modern 11s or 12s setup, or even upgrading your E-bike, the Helix Race delivers a superior experience.
The Direct Mount interface provides a clean, stiff, and lightweight connection to your crankset, eliminating the need for a separate spider and bolts. This not only simplifies installation and reduces overall weight but also significantly enhances power transfer, ensuring every watt you produce is translated into forward momentum.
At the heart of its performance is the advanced M4 narrow-wide tooth profile. This meticulously engineered design ensures superior chain retention, preventing frustrating chain drops even when charging through the roughest rock gardens and root sections. It also significantly reduces drivetrain noise for a quieter, more focused ride and minimizes overall system wear, extending the life of your valuable chain and cassette.
Versatility is a core principle of the Helix Race design. The innovative reversible “Flip-Flop” feature allows you to easily switch between a 52mm chainline for Boost frames and a 55mm chainline for Super Boost frames. This ensures you can achieve perfect drivetrain alignment for crisp, accurate shifting, regardless of your modern frame standard.
Experience unparalleled compatibility. This chainring is engineered to work seamlessly with both SRAM™ and Shimano™ 11-speed and 12-speed chains, making it a versatile and hassle-free upgrade for a wide range of drivetrains. Its robust construction also makes it an excellent and reliable choice for the high-torque demands of E-bikes.
