Praxis Buzz

All other aftermarket rings are machined. For superior longevity and performance, we cold forge ours from 7075 T6 aluminum and hard anodize it for even more durability. They also feature our famous LevaTime Shifting Technology, which boasts synchronized ramps and strategically placed shift pins for perfectly timed shifts every time.

Use:

• traditional 5-arm AND 4-arm w/hidden 5th (SRAM Exogram) road cranks.
