Specifications

Elevate your downhill, bikepark, and freeride performance with the ethirteen Helix Race GR Direct Mount Chainring - a premium 36-tooth, silver-colored component engineered for durability, precision, and optimized riding efficiency. Specifically designed for use with Helix Race GR Cranks, this high-performance chainring features innovative tech and superior materials to withstand the rigorous demands of aggressive riding disciplines.

Materials & Construction:

Crafted from aircraft-grade AL-7075-T6 aluminum, the Helix Race GR chainring offers exceptional strength, stiffness, and long-lasting durability. Its CNC-machined construction ensures a precise fit, minimal weight (just 79 grams), and a sleek, professional finish that complements any bike setup.

Performance & Engineering:

Engineered for gravity-focused riding, this direct mount chainring is designed to deliver reliable chain retention, reduced system wear, and minimal noise. The -7mm offset creates a 56.5mm chainline optimized for long-travel mountain bikes with 83mm spindle cranks, ensuring compatibility with most modern downhill and enduro bike geometries.

Components & Technology:

Featuring ethirteen's proven Quick Connect Direct Mount system, this chainring guarantees secure attachment without creaks or slippage. Its M4 narrow-wide tooth profile enhances chain retention, minimizes derailments, and improves drivetrain efficiency. Compatible with both Shimano and SRAM 11- and 12-speed drivetrains, including T-type systems, the Helix Race GR chainring offers versatile integration for a wide range of mountain biking setups.

Style & Use Case:

The sleek silver finish offers a clean, professional look suitable for aggressive downhill, bikepark, freeride, and enduro riders who demand reliability and aesthetics. Designed to withstand the extreme impacts of downhill racing and park riding, it's perfect for riders looking to optimize their long-travel mountain bike's drivetrain for maximum performance.

Key Features:

- 36-tooth round design optimized for 11/12-speed drivetrain compatibility
