SRAM’s Eagle drivetrains set the benchmark for mountain bike drivetrains and now that same technology is now available at a more affordable level thanks to the new GX Eagle DUB groupset. Using all the technology crammed into their higher-end groupsets, GX Eagle sets a new standard for performance and value for money.10-50t cassette provides massive 500% gear range, making steep climbs a breezeForged aluminium cranks are strong & incredibly stiff while forged X-Sync 2 chainring provides excellent chain retentionRear derailleur features a Type 3 clutch to provide perfect chain retention and smooth shiftingErgonomically designed trigger shifter shifts between gears seamlessly, even under loadSmooth shifting & highly durable chain with cutting-edge Flow Link designThe centrepiece of SRAM’s Eagle drivetrains are the 12-speed cassettes, and the XG-1275 Eagle Cassette forms the centrepiece of the GX Eagle groupset, by providing the same wall climbing 50t bottom cog as the other groupsets, while the use of a 10t top cog means you can run a smaller chainring for improved ground clearance and even lower climbing gear, without giving up on top-end speed. Conversely, the massive 500% gear range means you can run a bigger chainring if required and still have a low climbing gear, yet have a higher top speed compared to other 1x drivetrains. Based around SRAM’s DUB 28.99 axle standard, the GX Eagle DUB crankset features 6000-series forged aluminium arms that are both strong, stiff and lightweight and when used in conjunction with SRAM’s DUB bottom brackets provide a smoother running and more durable system. The DUB system replaces SRAM’s previous GXP and BB30 crank and bottom bracket systems to provide improved durability, better compatibility and a stiffer, stronger and lighter product. DUB cranks can be used with any existing bottom bracket standard when used with the appropriate DUB bottom bracket. Performance benefits aside, it also means your crank is future proofed in case you happen to swap your frame. SRAM’s X-Sync 2 chainrings set the standard when the design was first released alongside the XX1 and X01 Eagle drivetrains and the GX Eagle DUB crankset uses a forged version that uses the same unique hooked tooth profile that tenaciously holds the chain in place as well as improving durability of the chainring and chain.The GX Eagle Rear Derailleur features SRAM’s X-Actuation technology which has been developed specifically for SRAM 1x drivetrains to ensure that shifting remains sharp, smooth and consistent across the entire cassette. The GX Eagle Trigger shifter uses the same ergonomic design as SRAM’s higher end shifters and carries over many of their features, including Zero Loss to provide instant and responsive shifting as well as being MatchMaker X compatible, so it can be easily synced with SRAM brake levers to leave a clean, uncluttered cockpit. Using the same design and manufacturing techniques as SRAM’s higher end Eagle chains, the GX Eagle Chain uses a highly durable solid pin construction and clever link profile to provide precise and slick shifting under even the harshest conditions. The unique profile also provides significantly reduced wear on Eagle cassettes and chainrings, massively extending the usable life of your drivetrain. SRAM’s PowerLock quick links also make installation and removal a breeze. SRAM’s GX Eagle DUB Groupset may cost a fraction of their higher end groupsets, but the performance is still exemplary and it packs an almighty punch without putting too big of a dent in your wallet. Wide range 1x drivetrains are now more attainable thanks to GX Eagle.
