Truvativ: BORN FROM THE MOUNTAIN The Descendant 6K crank set delivers consistent performance every time out. Featuring SRAMs X-SYNC2 tooth profile chaining, the Descendant crank set is engineered for complete chain control. Each tooth's thickness is precisely tolerance and controlled to work seamlessly with the SRAM chains inner and outer links. 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.
