GX Eagle DUB Crankset

Standing for Durable Unified Bottom Bracket, or DUB for short, SRAM's latest push forward in crankset technology unifies all major bottom bracket standards under a newly introduced spindle diameter of 28.99 millimeters, versus the previous 30 and 24-mililmeter spindles used by SRAM. Ultimately, that means the GX Eagle DUB Crankset is compatible with virtually any mountain bike, regardless if your frame uses a threaded, Press Fit, BB30, or PF30 bottom bracket.

When DUB was announced, we could already envision the eye rolls of the mountain bike community, seeing the changing standards seemingly imposed with every passing year. However, just hear us out before clicking away. SRAM focused entirely on improving the bearing longevity and sealing of DUB, then designed the spindle diameter to meet these needs, meaning it's ready for riding in wet and nasty conditions. SRAM was able to engineer a new crankset that's every bit as light and stiff as those with 30-millimeter spindles, but one that provides the increased bearing life of 24-millimeter spindles. It's really a simple concept and one that elevates SRAM's Eagle DUB Cranksets to the top of the market, thanks to an optimal mix of lightweight efficiency, stiff pedaling, and robust durability across all twelve gears.

Seeing you don't need a major overhaul in components to run DUB Cranks, it doesn't feel so much like a newly imposed standard, but more like the next step in SRAM's continuously evolving line-up of drivetrain components. Of course, you will have to purchase a new DUB-specific bottom bracket for this crankset to work, but it's really a small compromise considering the system's ideal blend of lightweight performance and bearing longevity. Although SRAM tried to accommodate every major bottom bracket found on mountain bike frames, there are two types that aren't compatible, including those running Super Boost rear axles, as well as those using Cannondale's BB30 Ai bottom brackets.

Outside of the DUB standard, the GX Eagle DUB Crankset is ideal for the everyday rider who demands reliability and efficient pedaling, but one that's not overly concerned with counting every last gram. It's made of 7000-series aluminum for optimal strength-to-weight, and a much lower cost than carbon offerings, such as XO1 and XX1. This particular version works with tried-and-true 12 x 142-millimeter rear axle spacing found on trail and all-mountain rigs.

Great If You Don't Care About The Weight

It performs great, you might need a 30T chainring if you plan on doing lots of hill climbing. If you do care about the weight, look for a X01 or XX1 crankset


hi will this work with a cannondale frame's ai 6mm offset chainring
