Oh, this is definitely not a new standard…
The folks have SRAM have dropped an all new crank and BB system aimed at optimizing the balance between weight, stiffness, and bearing life all while being agnostic to frame design. With 7 new crank sets and 8 BB types to fit pretty much any frame on the market, unless that bike happens to be a DH rig. There are no DH level cranks supported in DUB just yet. There’s a lot to take in, including a claimed 78g weight loss in a 175 mm XX1 crank with 32t chainring and BB which makes it ever so slightly lighter than an equally spec’d Race Face Next SL G4. Full details below…
Forward thinking and backwards compatible SRAM DUB™ BB/Crank technology is the workhorse without restraint. Designed for the most discerning pros. And riders who set it and neglect it. DUB™ is compatible with all major bottom bracket standards. Offering better sealing than ever before, without having to make compromises to fit all frames. Yet it opens the door for a new crank spindle for the world’s all-time lightest crank set. It’s a new approach that embraces the old. And it’s about time.
DUB CRANKSETS
XX1 EAGLE DUB SL CRANKSET
True competitors are always looking for a performance advantage — a relentless pursuit of equipment that is lighter, stiffer, stronger and more durable. To create the best drivetrain possible, we re-examined and re-engineered our crankset design. Our all-new XX1 Eagle™ CARBON TUNED™ crankset is our lightest, stiffest and strongest to date. SRAM DUB™ technology enhances this by simplifying the relationship of the spindle to the bottom bracket, and redefining the measure of durability. DUB™-powered cranksets mean simplicity, compatibility and durability.
FEATURES/BENEFITS
DUB™ technology delivers the lightest, stiffest,
strongest crankset available
All-new SRAM CARBON TUNED™ crank technology
provides extreme stiffness and light weight
The X-SYNC™2 chainring provides significantly
quieter performance, with better mud clearing and
extraordinary durability

$515 – $525 | €570 – €585 | £510 – £520
X01 EAGLE DUB CRANKSET
We know you have a lot of choices when choosing a crankset, and your choice says a lot about your personal style. We designed the new X01 Eagle™ crankset for riders who feel most stylish when they stand on top of the podium. This is a completely reengineered design, employing our proprietary CARBON TUNED™ lay-up technology. Built tough, to handle aggressive lines through rock gardens and big hits wherever you find them. The new X01 Eagle™ is our best, toughest and most aggressive Trail and Enduro crankset thanks to SRAM DUB™ technology, which features a better-engineered bottom bracket and a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination—and define a new measure of durability. If you’re into that kind of thing.
