Sram GX Eagle 1×12 Dub Lunar crankset

SRAM GX Eagle DUB 1x12 speed crank

Some people push their limits more than others. It is precisely this type of biker that the GX-Eagle-DUB crank allows you to give everything. In every lap. It's the best aluminum crankset Sram has ever built. Uncompromising reliable performance on every ride! With the 2-tooth X-SYNC profile, the chainring ensures perfect chain guidance.

Reliable performance without compromise: the GX Eagle crank from Sram

The material thickness of each tooth has been precisely adjusted to ensure optimal interaction with the chain links. DUB technology allows for a better sized bottom bracket and new shaft design. Together, these elements enable a coordinated approach to bottom bracket fit, dirt retention, backward compatibility, and future-proofing. Simply put, the GX-Eagle DUB forged crank is the worry-free package for riders who give it their all.

DUB™

Designed for the future yet fully compatible with the past, DUB™ bottom bracket and crank technology is a workhorse that never gives up. Designed for the most demanding professional motorcyclists and for those who do not want to worry about anything after installation. The DUB™ is compatible with all common bottom bracket standards. The system has a better seal than in the past and adapts to any frame. At the same time, it paves the way for a new type of crank spindle and thus the lightest crankset in the world to date. It's a new approach that incorporates the old. It was time.

After a long period of research, Sram is standardizing the diameter of bicycle crankshafts and bottom brackets to 28.99mm starting in 2018. The new DUB (Durable Unifying Bottom Bracket) bearing technology will henceforth set new standard.
