LEAD TIME: Hope is currently experiencing delays on orders of up to 6 weeks.
Hope's threaded bottom bracket is ready to take on the hardest riding conditions. Precision-machined aluminum cups deliver the smoothest possible seal while the system's replaceable stainless steel cartridge bearings ensure easy maintenance. In addition, a high-quality double seal provides unmatched durability that will keep your drivetrain running smoothly through the worst weather conditions.
The Shimano bottom bracket was not robust enough. The bigger bearing makes the part durable and longer lasting. Note: The part is used as a bottom bracket bearing and as a knuckle hub bearing on the front wheels of the trike.
