Die SRAM DualDrive Schalter und Clickbox: Unterschied zwischen den Versionen

The SRAM DualDrive hybrid-gearing system had a three-speed internal-gear hub and a splined cassette body to mount a Shimano-Hyperglide-compatible 8-, 9- or 10-speed cassette. The system included the hub and cassette, a rear derailer, clickbox, cable and a combined dual-shifter assembly for flat handlebars. The hub was shifted by a thumb-lever mechanism, and the derailer, by a twist grip. Cassettes could have 8, 9 or 10 sprockets. The cassette assembly was compatible with most Shimano derailers, but the SRAM derailer used SRAM's longer cable pull. The hub could be shifted by the combined SRAM shifter or by the one for the SRAM i-Motion 3 hub -- an unintended compatibility. When using the combined shifter, derailer choices are limited to those of the SRAM 3.0 system.

The DualDrive hub is no longer in production, though as of 2022, replacement parts may be found with an eBay search, and some shops still have them. Bike Friday sold many bicycles with DualDrive hubs.

The image below shows a shifter assembly for a DualDrive system with a 9-speed cassette. The shifter assembly for an 8- or 10-speed cassette is different, due to the different number and spacing of sprockets. Installation of cables in the shifter requires disassembly -- see directions linked at the end of this page.
