When we put together a new assembly or replace a worn crankset We count on the Descendant 6K Eagle DUB crankset for its simplistic design and bomber reliability. Like other Descendant Eagle cranks The DUB model features a SRAM X-SYNC 2-tooth tooth profile Known for its control and holding the chain in place on steep descents as well as on steep climbs. Featuring 6000 Series forged aluminum construction, we're happy to install these cranks on everything from XC to enduro bikes, thanks to their rugged construction.
