Strong, tough, and durable is how we're describing ourselves.. and the SRAM Descendant Eagle 7K DUB Crankset. This crankset delivers on its dependability, seeing its way through whatever mess we get ourselves into. The stiff forged-aluminum body doesn't flex on impact and they'll deliver every watt we put through the pedals into the wheels. These cranks are heavy and that's the way we like it, they're outlasting most bikes and taking hit after hit without complaint.
