The tooth core is made from 7075-T6 aluminum alloy, which is the toughest aluminum around! This allows for optimal power transfer and superior wear resistance. It's smartly surrounded by carbon fiber, which minimizes friction and chain rattling, giving you a lightweight and sleek chainring design.


You’ll experience an unmatched smoothness while pedaling.

Get ready to stand out from the crowd with Rigel, the ultimate carbon chainring for your SRAM 8 Bolt. This genius design not only beats traditional chainrings in weight, aerodynamics, and power transfer, but also adds serious style to your ride (seriously, it's a showstopper). Prepare to turn heads and leave your biking buddies in awe - Rigel is like nothing you've ever seen before.

Rigel's carbon fiber comes from the same stuff used in supercars, but it's created in a completely unconventional way. Using 100 tons of precise pressure and our own innovative techniques, Rigel stands out as a one-of-a-kind technology leader. We've even filed 2 international patents for this cutting-edge chainring.

In the production process, the carbon fibers are meticulously placed around the anti-wear metal core in a concentric manner, giving the teeth unparalleled strength. This technique cannot be replicated with traditional carbon fiber methods like layering or CNC-machining.
