Truvativ: BORN FROM THE MOUNTAINThe Descendant 6K crankset delivers consistent performance every time out. Featuring SRAMs X-SYNC2 tooth profile chainring, the Descendant crankset is engineered for complete chain control. Each tooths thickness is precisely toleranced 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.
