The Rohloff Speedhub is an epicyclic internal hub gear for bicycles, developed and patented by Rohloff AG. It has been manufactured and marketed by that company since 1998.

At the 1996 IFMA in Cologne, Rohloff announced a 14-speed gear hub with a weight of 1700 grams. At the time, the gear hub with the greatest number of speeds was the unreliable 3700 gram 12 speed Sachs Elan (discontinued by 2000), made by the hub-gear manufacturer Sachs (later acquired by SRAM).
The 14-speed Rohloff Speedhub hub gear, introduced in 1998, has a range exceeding 5 to 1, and is thus comparable in range to 24, 27 and 30-speed derailleur systems (with 3×8, 3×9 and 3×10 cogs front and rear), since the latter have three overlapping ranges often with only about 14 distinct gears. As there is no overlap with the Speedhub, the ...
The overlapping ranges with derailleur gears mean that 24 or 27 speed derailleur gears may only have the same total gear range as a (much more expensive) Rohloff 14-speed hub gear. Internal hub geared bikes typically have a more restricted gear range than comparable derailleur-equipped bikes, and have fewer ratios within that range.
The only application currently commercialized is the internally geared bicycle hub. The NuVinci CVT replaces derailleurs and other internally geared hubs, and provides a gear ratio range of about 350%, similar to that on bicycles with 8- or 9-speed hub gears, or with double chain rings (most racing or fast road bicycles). [12]
In particular, the Rohloff 14-speed hub with a gear range of over 500% has been used on at least two around-the world bicycle tours. Internal-geared hubs have a couple of advantages over traditional derailleur gears, in that they can use stronger chains [citation needed] as generally a single sprocket and chainring combination will be used ...
Internal hub gearing is most common in European utility bicycles, usually ranging from three-speeds to eight speeds, however hub gears with fourteen (Rohloff-drive) or eighteen (Pinion-drive) speeds are also available. Retro-Direct bicycles have two sprockets on the rear wheel. By back-pedalling, the secondary, usually lower, gear is engaged.
