SRAM XX1 Eagle DUB SL Crankset

Why We Like The XX1 Eagle DUB SL Crankset

Tipping the scales at a paltry 422 grams, the SRAM XX1 Eagle DUB SL Crankset is one of the lightest cranks available on the market, lending itself to professional racers and discerning cross-country riders shaving weight from their Eagle 12-speed drivetrain. You´ll find it´s approximately 43 grams lighter than previous XX1 Eagle Cranksets with its new spindle diameter and Carbon Tuned crank arms (80 grams less with DUB bottom bracket), which is a big deal when you´re counting every last gram that goes on your cross-country race bike. Additionally, it retains the quiet, mud-shedding performance of the X-Sync 2 chainring, plus the ability to retain your chain without a guide. Please note, this particular version is made solely for 12 x 142-millimeter rear axle spacing.

Not only is the XX1 Eagle DUB SL Crankset lighter than ever, but it´s more durable with its newly introduced 28.99-millimeter spindle diameter, versus the previous 30 and 24-millimeter spindles used by SRAM. SRAM termed this new standard as DUB, which stands for Durable Unified Bottom Bracket, seeing it´s compatible with virtually any bottom bracket standard on the market—whether your frame´s using a threaded, Press Fit, BB30, or PF30 bottom bracket.

Upon introducing this 28.99-millimeter spindle diameter, SRAM aimed to improve bearing longevity and seal out moisture, then designed the spindle diameter to meet these needs, meaning it´s ready for riding and racing in the wettest, nastiest conditions of the year. This lead SRAM to engineer a new crankset that´s every bit as 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 ultra-light 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 extremely low weight and improved durability. Although SRAM tried to accommodate every major bottom bracket on the market, 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.
