With the success of our 27.5” adventure model Pangaea, some customers asked whether we can offer a model built exclusively for internal gear hub use. Now the prophecy comes true , Pangaea EBB (eccentric bottom bracket) can be equipped with internal gear hubs without chain tensioner by rotating EBB module. Internal gear system is without rear derailleur, so the transmission system is clean and has less possibility to break down. Moreover, the rear dropout is optimized for the Rohloff OEM2 axle plate, integrated with rack eyelets. So Pangaea EBB supports Rohloff Speedhub and other 135mm O.L.D internal hubs as well.
