Description

Why We Like The Descendant Carbon Eagle DUB Crankset

Just because you like to charge head first in to chunky rock gardens doesn't mean your crankset has to scale in at sky-high downhill-grade weights. Let the Truvativ Descendant Carbon Eagle DUB Crankset with Boost spacing shed some grams on your Eagle setup, while giving you the heavy-metal feel that you trust for busting out enduro laps. This crankset combines Truvativ's proprietary carbon fiber crank arms with the new DUB spindle, compatible backwards and forwards with just about any bottom bracket standard you can dream up, to provide a solid ride feel that doesn't waiver under pressure.

DUB technology takes the ever changing bottom bracket standards and throws in a uniform approach, offering a spindle that securely fits into any SRAM DUB bottom bracket, which is available in an array of standards, from English threaded, to PF30 and BB30, with more on the way. This means that regardless of the bottom bracket shell standards you're running, you'll be able to pair this wide and stable spindle in a bottom bracket that fits your bike just right. Because the spindle and bottom bracket are designed to pair together, you'll find a better seal against contamination, making it an ideal setup for those of us who ride in sandy, muddy, or wet conditions.

The Descendant Carbon Eagle crankset also gives you the benefit of running with an Eagle drivetrain. It uses SRAM X-Synch 2 technology, with more aggressive teeth that are designed for improved chain retention, and a smoother, more efficient pedal stroke feel. It's is compatible with any level of Eagle from GX to XX1, as long as its paired with an Eagle chain. This makes for a seamless interface, with the svelte look of carbon to give you XC weights with enduro-ready durability.

These replaced GX alloy cranks. The ride improvement was noticeable. If you want the great performance of a carbon crank without spending a ton this is the one. Graphics are low key in a good way, the cranks are very good looking. They deliver the stiffness to improve power transfer into the drivetrain, I agree with another reviewer that they have some damping qualities as well. If you are a smaller rider you might not notice the difference between alloy and carbon but for those on the larger side when you get out of saddle and crank the difference is obvious. I will buy these again for a hard tail build I am working on.

Carbon Descendant crank that’s uber-stiff and really does help mute the chatter through your feet and keep them planted. I’m a 32” inseam on a large v3 Bronson and moving to 170mm has helped me spin a higher cadence while climbing. Already have the DUB system, so these with some crank boots was all I needed. Could not be more pleased with this crankset

Very happy with this crankset. Upgraded from a GX aluminum crankset but didn't want to drop over $400 for a carbon crank. This isn't the lightest crankset, like the XX1 or XO1, but it's not that far off. Going from an aluminum GX crankset with GXP BB to this crankset with the new DUB BB, the weight savings was exactly 100g. (oh and I moved from 175mm to 170mm crank arms at the same time) This crankset looks fantastic, but aesthetics aside, the most noticeable thing for me what the stiffness. It's notably more stiff while pedaling and especially under hard efforts out of the saddle, like downhill sprints. It feels like all of my effort is translated into forward momentum with very little flex. I can't say if this is because of the carbon layup, or perhaps it's the DUB spindle, I don't know. My old GX cranks was a smaller diameter GXP BB version. The bearing pre-load that they put on these is also really great. Simple concept to dial in just the right amount of tension on the bearings for butter smooth operation with zero play. Do note that if you aren't already running a DUB bottom bracket, you will need to get one. They don't cost much and the BB weighed substantially less than my GXP BB. Also note that if you are using a threaded BSA style BB, you will need a different 12-tooth BB tool for the DUB bottom bracket. It's NOT the same tool as the GXP or shimano BB. If you are thinking about a new crankset, throw down. This thing rocks. Oh, and don't forget the crank boots for the ends.

Great Value

These are a great option if you're looking for a carbon crankset, but don't want to spend $400-$500 for Race Face or X01 / XX1. They look great on any bike, are pretty light and deliver excellent performance.

>Rating:

Are these cranks compatible with my 2018 Yeti 5.5 GX Eagle build?

Yes. All SRAM Eagle products work with each other. GX can be used with XX1, X01, or NX. They all work with one another

Hello Brett, Yes, this crankset is compatible with the 2018 Yeti 5.5 as long as the proper bottom bracket is used. The bottom bracket you would need can be found on our site by searching item SRM00D5. Please do not hesitate to contact us if you have any additional questions or need anything else.

Dub makes it easy

Familiarity:
I've put it through the wringer

Dub takes the questions out. Plus the cranks are sick looking and stiff AF. Slightly heavier than XO, but worth the increased durability, IMO.

Worth the money

I've had this crank on a couple different bikes now and have been quite impressed with it. For the money, it's pretty light, holds up to a lot of abuse, and looks good on the bike. The DUB platform helps save a bit more weight off, while still seeming plenty stiff for your average rider. I usually put the small crank boots on the arms to keep marks from pedal strikes at a minimum.
