5DEV T-Type Aluminum Chainrings

5DEV T-Type Aluminum Chainrings are precision CNC-machined in San Diego, California, and built to meet the demands of modern high-performance drivetrains. Available in both round and oval profiles, these chainrings are designed for riders who want clean aesthetics, precise chain control, and reliable performance across trail, enduro, and e-MTB applications.

Engineered for compatibility with SRAM Transmission (T-Type) as well as SRAM Eagle and Shimano 12-speed chains, the T-Type Aluminum Chainrings deliver consistent engagement and smooth power transfer under load. A 3mm offset paired with a 52–55mm chainline makes them well suited to modern wide-chainline frames and aggressive riding setups.

These chainrings are offered with both SRAM 3-bolt and 8-bolt mounting standards, allowing seamless integration with a wide range of cranksets. For riders running high-pivot suspension designs, fitment can vary—verification is recommended before installation to ensure optimal compatibility.
