The svelte strength of carbon fiber with the swagger of heavy metal. The Descendant carbon crankset uses a proprietary TRUVATIV carbon construction process that delivers a crankset light enough for XC, yet bold and badass enough for Enduro. Style and substance - Descendant. SRAM DUB™ technology features a better-engineered bottom bracket and a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of durability.

What is Chainline and why does it matter?

Chainline is determined by the dimensional relationships between the frame, cassette, and chainrings. Incorrect chainline can cause poor shifting, excessive friction and wear, and unintended shifting. Incorrect chainring spacing can also affect chainline.

The Descendant Boost carbon crankset has a 52.0mm chainline for bikes with 148mm (Boost) rear frame spacing.
