Some riders test their limits more than others. For these riders, the GX Eagle DUB crankset allows them to go all-in every day they ride. The best aluminum crankset SRAM makes, engineered to deliver consistent performance every ride. Featuring SRAM's X-SYNC 2 tooth profile chainring for complete chain control. Each tooth's thickness is toleranced and controlled to work seamlessly with the chain's inner and outer links. DUB technology’s patented spindle design and bottom bracket provide a uniform approach to fitment, better sealing, and forward and backward compatibility. Simply put, the forged aluminum GX Eagle DUB crankset is the no-frills choice of riders who know.

Fast action great customer services

i ordered a wrong size of crank boost wide, which i need just the regular boost. their customer service is fast, sending me the replacement and ROI and i am one happy customer. buying more parts from them great customer service

Drew Sheffield
Perfect for Status160

Went with 165mm on the Specialized Status160. Way less pedal strikes and no noticeable loss in power. Look way better than the NX as well.

Michael Danque
Fantastic midrange option especially for older bikes in non-boost spacing

Shimano options now share the same chainline for boost and non-boost which is around 50-53mm (too wide for non-boost) and have limited aftermarket support for chainrings. This SRAM GX crankset option weighs in at same or less than XT, is cheaper, and runs a 49mm or so chainline which is ideal for non-boost setups. I put this on my step daughters circa 2012 Specialized Myka to achieve a 1x11 setup in combination with shimano XT derail and shifter, shimano slx cassette, and shimano hg chain which were had on sales. It is perfect in function. Combined with a wheelset and a manitou fork, we dropped 5-6 lbs mostly rotational and unsprung, picked up air fork, went tubeless, and went 1x11 from 3x8. It is a whole new bike for far less than a whole new bike would have cost. Nice bike in adult extra small for a 10 year old and instantly she got fast and started being able to lift the front and flow. The SRAM GX cranks are well finished, have good chain ring support, have a perfect chainline, and work with shimano stuff too. As for Thunder Mountain...they have stock when no one else does, ship very quickly, and it arrives very quickly. I cannot fully convey how great this all was.
