Sheldon Brown's Internal-Gear Hub Cable Pull Crib Sheet


find us on FB

Spoke Divider

The tables in this cribsheet identify compatibility of shifters and internal-gear hubs currently or recently in production as of 2014, and one antique. The first table lists hubs by brand, the second table, by number of speeds, and the third table, by average cable pull.

Many of these measurements were taken with Alex Wetmore's cable pull measuring tool (image below by Alex Wetmore). Harris Cyclery provided shifters to be measured. Jeff Meredith and Michael Wilson contributed measurements of several shifters. David Choma contributed measurements for the newer Sturmey-Archer 8-speed. Bruce Dance contributed many useful suggestions.

Wetmore cable pull measuring tool

The main point this page makes is that most internal-gear hub shifters are not interchangeable. Using a non-standard shifter will violate warranty terms and may damage a hub or result in its shifting into a "neutral" gear where the pedals spin forward -- possibly causing a crash. Please read the notes below before considering a substitution.

To use this table, first check the Av.(erage) column (third from right), to get into the "ballpark" of matching cable pulls. Then check whether the substitute shifter has at least the same number of speeds as the design shifter; and finally, whether the individual cable pull increments are compatible.
