SRAM, who you probably recognize as legends of the bike component world, just announced their new DUB line of cranksets and bottom brackets, aimed at unifying the confusing world of bottom bracket compatibility with frames, cranks, and spindles. Here you’ll find everything you need to know about the new line, straight from SRAM themselves.
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.
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
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.
FEATURES/BENEFITS
- DUB™ technology delivers the strongest, stiffest, lightest crankset available
- SRAM CARBON TUNED™ crank technology provides extreme stiffness and light weight
GX EAGLE DUB CRANKSET
The SRAM GX Eagle™ crankset delivers consistent performance every time out. Featuring SRAM’s X-SYNC™2 tooth profile chainring, the GX crankset is engineered for complete chain control. Each tooth’s thickness is precisely toleranced and controlled to work seamlessly with the chain’s inner and outer links. SRAM DUB™ technology 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 forward and backward compatibility. Now everyone can benefit from a new measure of durability.
FEATURES/BENEFITS
- Optimized 7000 series forged aluminum arms
- DUB™ technology features a uniform approach to bottom bracket fitment, better sealing against contamination and is forward and backward compatible
DESCENDANT CARBON DUB CRANKSET
The svelte strength of carbon fiber with the swagger of heavy metal. The Descendant carbon crankset uses a proprietary TRUVATIV carbon construction process that delivers a crankset light enough for XC, yet bold and badass enough for Enduro. Style and substance – Descendant. SRAM DUB™ technology 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 forward and backward compatibility. Now everyone can benefit from a new measure of durability.
FEATURES/BENEFITS
- Carbon construction for lightweight durability
- DUB™ technology features a uniform approach to bottom bracket fitment, better sealing against contamination and is forward and backward compatible
- Fully compatible with any 1x drivetrain
DESCENDANT 6K DUB Crankset
The Descendant 6K crankset delivers consistent performance every time out. Featuring SRAM’s X-SYNC™2 tooth profile chainring, the Descendant crankset is engineered for complete chain control. Each tooth’s thickness is precisely toleranced and controlled to work seamlessly with the SRAM chain’s inner and outer links. SRAM DUB™ technology 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 forward and backward compatibility. Now everyone can benefit from a new measure of durability.
FEATURES/BENEFITS
- Optimized 6000 series forged aluminum arms
- DUB™ technology features a uniform approach to bottom bracket fitment, better sealing against contamination and is forward and backward compatible
STYLO CARBON DUB CRANKSET
We designed the new STYLO Carbon crankset for riders who feel most at home when riding endless single track. This is a completely new crankset, employing our proprietary layup technology. Built tough, to handle lines through rock gardens and trail, the new STYLO Carbon is strong, stiff and light. Combined with the new SRAM Eagle™ direct mount chainrings, and as a compatible crankset to the Eagle™ drivetrain. SRAM DUB™ technology 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 forward and backward compatibility. Now everyone can benefit from a new measure of durability.
FEATURES/BENEFITS
- Proprietary carbon layup technology
- Fully compatible with any 1x drivetrain
- DUB™ technology features a uniform approach to bottom bracket fitment, better sealing against contamination and is forward and backward compatible
