Quarq sollte gleichzeitig kommen.
Wo steht was von einem neuen Tretlager??

SRAM is bringing its new DUB bottom bracket design over to the road, too. First introduced on the company’s mountain bike range last year, the 28.99mm-diameter (yes, really) aluminum spindle is intended to provide nearly identical stiffness to 30mm-diameter designs, but with better bearing durability since the balls inside each cartridge can be made slightly bigger.
SRAM claims an improvement in terms of frame compatibility, too, although in reality, DUB doesn’t fit anything that isn’t already compatible with wide-format 30mm systems (such as from Easton, Rotor, and Praxis). And similarly, DUB doesn’t fit Trek’s proprietary BB90 and BB95 frames, either.
