DUB™
Forward thinking and backwards compatible 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.

After extensive research, Sram unifies the diameter of bike crankshafts and inner bearings to 28.99mm from 2018. The new bearing technology DUB (Durable Unifying Bottom Bracket) sets new standards from now on.

X-Sync™
X-SYNC™ 1x-Kettenblätter von SRAM sorgen für höchste Performance und Haltbarkeit. Die langen SRAM X-SYNC™-Zahnkanten greifen die Kette früher als traditionelle Zähne in Dreiecksform. Das scharfe und schmale Zahnprofil sowie die abgerundeten schrägen Kanten unterstützen die Kettenführung. Um auch bei schlammigem Terrain die bestmögliche Leistung zu bieten, verfügen die X-SYNC™-Kettenblätter über Vertiefungen zum Abtransport von Schmutz und Matsch für die inneren Kettenglieder und -rollen. Die in Deutschland hergestellten X-SYNC™-Kettenblätter sind ein wichtiger Bestandteil des 1x™-Antriebs von SRAM.
