Descendant 6K Eagle DUB Crankset

To make life a little easier for those of us who prefer maximum time on the trail, and minimum time deciphering bottom bracket standards, TruVativ introduces the Descendant 6K Eagle DUB Crankset with Boost spacing. This innovative crank combines SRAM's DUB technology that simplifies bottom bracket standards by creating a standard spindle diameter, and pairing it up with bottom brackets with shells to match any standard on the market, so you can rest easy knowing your crank upgrade can carry on to your next bike — and the bike after that. Just as you'll find on other Descendant Eagle cranks, the DUB model features SRAM's X-SYNC 2 tooth profile known for commanding control and keeping your chain locked in place through rugged descents and rooty climbs alike.

6000-series forged aluminum construction maximizes caters to discerning trail riders and enduro racers seeking stiffness and strength without the higher cost of its carbon crank brethren. The chainline is three millimeters wider to accommodate the Boost spacing of modern trail and enduro machines. Choose between 170 and 175-millimeter crank arm lengths, depending on your riding preferences and intended usage on the trail. It's compatible with SRAM DUB bottom brackets for any shell standard, and works exclusively with 148mm Boost spacing. The 32-tooth direct-mount Eagle chainring must be paired with a SRAM Eagle chain and cassette, and its spindle must be paired with a DUB bottom bracket of your choice.

  • Future-proof cranks for shredding with Eagle drivetrains
  • X-SYNC 2 offers maximum chain retention
  • 6000-series aluminum construction for strength and stiffness
  • Designed for SRAM 1x12 Eagle drivetrains
  • Compatible with any SRAM DUB bottom bracket for any shell size

What do you think about this product?



Will this fit on a bike with a 83mm bottom bracket shell length?

Hi Gabriel, Yes this crankset works as long as you pair it with SRAM's DUB Press Fit BB (search SRM00D7 on our site) assuming you have a press-fit style bracket shell.


I’m planing on using this for a single speed set up. Can I use any chainring on the rear or do I need a sram specific one? If so why?


Gud day, is my KMC X12 gold chain comptible with this crank? TIA
