One standard option for the Brompton folding bicycle is to use a 3-speed hub gear (roughly a 30% difference between gear ratios) in combination with a 2-speed derailleur gear (roughly a 15% difference) to give 6 distinct gear ratios; this is an example of half-step gearing. Some Brompton suppliers offer a 2-speed chainring 'Mountain Drive' as ...
A twist-style 14-speed indexed shifter made by Rohloff A bicycle shifter or gear control or gear levers is a component used to control the gearing mechanisms and select the desired gear ratio . Typically, they operate either a derailleur mechanism or an internal hub gear mechanism.
Shimano STI Dual Control shifter and brake lever: 1. Main lever 2. Release lever A. Pulling the main lever towards the rider applies the brake B. Pushing the main lever towards the center of the bike downshifts one, two or three gears depending on how far the lever is pushed (right hand shifter) or changes from a small chainring to a larger chainring (left hand shifter)

As there is no overlap with the Speedhub, the hub gear has only two shift directions (up and down), compared to front and rear derailleur gears where two shift operators with two shift directions are needed to shift through all gears. The 11-speed Shimano Alfine 700 hub gear, introduced in 2010, has a gear range exceeding 4 to 1, comparable to ...

Also, the gear units were able to be shifted under moderate pedaling loads. Shimano had manufactured three speed hubs prior to that, and these hubs were at that point re-branded Nexus. In the early 2000s the 8-speed Nexus hub gear was introduced, having two stepped planetary series mounted downstream of each other.
All Sturmey-Archer gear hubs use epicyclic (planetary) geartrains of varying complexity. The AW is the simplest, using one set of planetary gears with four planets. The AM uses three compound planets with differently sized cogs machined from a common shaft to engage the gear ring and sun gear separately, while the close-ratio three-speeds, and hubs with four or more speeds, use multiple ...
