A machined alloy ring for SRAM Transmission builds, in both of SRAM's direct mount patterns. 5DEV CNC-machines the T-Type ring in San Diego with a 3 mm offset for a 52–55 mm chainline, and it runs on Transmission, Eagle and Shimano 12-speed chains.
Highlights
- SRAM 3-bolt or 8-bolt direct mount
- 3 mm offset, 52–55 mm chainline (5DEV)
- Runs SRAM Transmission (T-Type), SRAM Eagle and Shimano 12-speed chains
- Round rings in 30T, 32T or 34T
- CNC-machined in San Diego, California
3-bolt or 8-bolt?
SRAM uses two direct mount patterns and a ring only fits the one it's made for. Check whether your crank takes a 3-bolt or an 8-bolt ring and pick that option. Not sure? Send us a photo of the drive-side arm or bring the bike in.
High-pivot bikes
5DEV asks high-pivot owners to check with it before buying to make sure the ring suits their setup. Ask us and we'll confirm it with the distributor.
Fitting
Fitting is a separate workshop service and isn't included in the price. On most cranks a direct mount ring swap means taking the drive-side arm off. The Tune workshop can fit the ring with the right tools, torque the bolts to 5DEV's spec (9 Nm for 3-bolt; 4 Nm in a star pattern for 8-bolt) and check your chainline and shifting.
Compatibility & fit
- Mount: SRAM 3-bolt or SRAM 8-bolt direct mount (choose the option that matches your crank).
- Offset: 3 mm; 5DEV quotes a 52–55 mm chainline.
- Chain: SRAM Transmission (T-Type), SRAM Eagle and Shimano 12-speed.
- High-pivot frames: confirm with us before ordering.
