Descendant Carbon Eagle DUB Crankset

The svelte strength of carbon fiber with the swagger of heavy metal. The Descendant carbon crankset uses a proprietary TRUVATIV carbon construction process that delivers a crankset light enough for XC, yet bold and badass enough for Enduro. Style and substance - Descendant. SRAM 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.

Threads stripped, crank ruined.

I've put it through the wringer
6' 3"

I got this crankset on a Yeti SB5 build from backcountry about10 months ago. Due to an injury the bike has seen only light use about 150 miles total. I'm a fast rider, but not abusive. Not hucking 5 foot drops or anything. Just got back from a ride where, 6 miles in my pedal started to feel floppy. I thought maybe the sole was coming off my shoe. When I stopped, my pedal literally pulled right out of the threads. I've never seen this happen before, it seems that the threads on the crank are softer than the threads on my pedals. Bad bad bad. Had a long walk to get back to the car. We'll see if BC will provide a replacement, but I was definitely disappointed with the failure mode. Most of my other bikes have had Shimano XT or XTR, and I've never seen this type of failure with those.
