SRAM X01 Eagle Boost Crankset
Strength is how the X01 Eagle DUB crankset takes capability to places never before reached. It’s the strongest crank in the entire Eagle ecosystem, and it holds this status at a weight that is hard to fathom. Featuring industry-proven and rider-beloved DUB technology to radically simplify the relationship of spindle to bottom bracket, delivering unprecedented simplicity, compatibility and durability.
- The X01 Eagle DUB Crankset also comes with our Eagle Colorsystem, in the X01 signature colorway - to go perfect with all other available cassette and chain colors – from Black to Gold to Rainbow, and now Copper
- With a raw aluminum finish on the X-SYNC 2 chainring teeth – to keep looking fresh throughout its long lifespan
Features
- The strongest crank in the entire Eagle ecosystem
- Available in the X01 signature colorway and Oxy Red X01 signature colorway
- Signature X01 colorway as part of Eagle Colorsystem
- Raw aluminum chainring teeth
Boost Compatibility
Designed specifically for Boost frame standards (148mm rear hub spacing and 110mm BCD for the crankset)
Made from forged aluminum, providing a strong yet lightweight design. This construction ensures the crankset is both durable and responsive, capable of withstanding the demands of aggressive riding. Features a direct mount chainring design for easy installation and removal. This system provides precise chain alignment and minimizes the risk of chain drops.
- Equipped with X-SYNC 2 chainring technology, which enhances chain retention and shifting performance. The design of the chainring improves engagement and reduces noise, especially in rough terrain
- Available in various crank arm lengths to accommodate different rider preferences and bike geometries, allowing for a more customized fit and performance
- Compatible with SRAM’s DUB bottom brackets, which provides a reliable and efficient interface between the crankset and the bike’s frame. This compatibility also contributes to the overall stiffness and durability of the crankset
X-SYNC 2
A proprietary tooth profile technology used in chainrings, particularly in mountain bike drivetrains.
- X-SYNC 2 chainrings feature a unique tooth profile that alternates between narrow and wide teeth
- It's designed to improve chain retention, reduce chain noise, and enhance overall performance
DUB
(Durable Unified Bottom Bracket) technology is a comprehensive system designed to improve the interface between the crankset and the bottom bracket on bicycles.
- DUB technology standardizes the bottom bracket spindle diameter across various bottom bracket shell widths, ranging from 68mm to 124.5mm for mountain bikes
- The DUB spindle diameter (28.99mm for MTB) is chosen to strike a balance between strength, stiffness, and weight savings
- DUB bottom brackets feature enhanced sealing to protect against contaminants such as dirt, water, and mud, which helps prolong bearing life and maintain smooth performance in all conditions
- DUB technology is compatible with a wide range of bottom bracket standards, including BSA, PressFit, BB30, PF30, and others, making it versatile for use with various bike frames and setups

This was a huge improvement over my SRAM Descendant 7K, DUB, Boost 170mm. The pedal power improvements were amazing.
