5DEV 3-Bolt Direct Mount T-Type Aluminium Chainring

The 5DEV 3-Bolt Direct Mount T-Type Aluminium Chainring is a precision CNC-machined drivetrain upgrade built for SRAM & Shimano Transmission systems with optimised 3mm offset and 52–55mm chainline. Machined in San Diego from high-grade aluminium, it delivers accurate chain retention, smooth load transfer and long service life. Full compatibility with SRAM Transmission, Shimano 12-speed and SRAM Eagle chains makes it a versatile choice for modern 12-speed setups.

Key Features and Benefits:

• CNC machined in San Diego, California: Each chainring is cut from aluminium using tight-tolerance CNC processes. This ensures consistent tooth profiles and exact mounting interfaces, which improves chain engagement and reduces premature wear across the drivetrain.
• SRAM 3-bolt direct mount system: The direct mount interface removes the need for a separate spider. This creates a stiff and secure connection to the crank, improving power transfer and reducing flex under load for more consistent shifting performance.
• Optimised 3mm offset with 52–55mm chainline: The built-in offset positions the chainring to achieve a correct chainline on compatible frames. This reduces cross-chaining stress, lowers drivetrain noise and improves chain retention during high torque efforts.
• T-Type compatible tooth profile: Designed for SRAM Transmission and compatible with Shimano 12-speed and SRAM Eagle chains, the tooth geometry supports modern flat-top and narrow-wide chain designs. This improves chain control and maintains reliable engagement under load.
• High-grade aluminium construction: The lightweight aluminium body balances strength and weight. This provides durability for aggressive riding while keeping rotational mass low, helping maintain efficient pedalling response.

Reliable chain retention and efficient power transfer are critical in modern 12-speed drivetrains. This chainring supports that goal with accurate machining, correct offset and a stiff direct mount interface. The controlled chainline reduces friction and wear, while the T-Type compatible tooth design maintains engagement under load. The result is consistent shifting performance and dependable drivetrain function over time.
