ROHLOFF SPEEDHUB 500/14
Get to know the Rohloff 500/14 Speedhub.
The Rohloff Speedhub is a planetary gear system with 14 gears. It is unique on the market with its large transmission range. It is at the top of the gear hub market, deservedly winning the most reliable gear hubaward. With proper maintenance, it has an exceptionally long service life. Thanks to its closed oil system, it’s a clean, low-maintenance solution that you don’t have to worry about when you use it in wet, muddy conditions.
Advantages of the Rohloff gear hub
Reliability and durability
The gears in the gearbox are very precisely and strictly controlled components, which is why the lifespan of Rohloff hubs is exceptionally long.
Wide gear range
Thanks to the 14 gears, there is no mountain that can be an opponent when climbing, and even speed hunters can step on the pedals comfortably. The name of the Rohloff Speedhub 500/14 refers to the large gear range. The total speed range is 526%. (The highest gear is 5.26 times higher than the lowest.)
Precise and smooth shifting
Thanks to the precise design of the gears, a very precise shifting experience is created. No stretch, no inaccuracy. Self-adjusting system, so readjustment is not needed.
Easy to use
It can be easily operated both while driving and in a stationary position. Do not shift gears under torque.
Low maintenance
The system is sealed, so it is enough to change the oil every 5000 km.
Value retention
Thanks to its reliability and durability, it is also in high demand on the used market and can be resold at a very good price.
Who do we recommend?
Bicycle tourers
If you’re going on long-distance bike tours, the Rohloff Speedhub can be extremely useful. Due to its reliability and durability, it provides reliable performance even on longer trips, and the easy handling helps you switching gears on different terrains.
Off-road and mountain bikers
The Rohloff Speedhub has 14 gears, making it an ideal choice for mountain biking. The wide speed range allows you to find the right speed for riding on steep climbs and technical terrain.
Cyclists who face extreme weather conditions
The closed system design of the Rohloff Speedhub hub makes it resistant to weather conditions. Therefore, it is recommended for cyclists who often find themselves in wet, dusty or muddy environments.
Cyclists who want to minimize the need for maintenance
The Rohloff Speedhub hub is low maintenance. The closed system protects the parts from dirt and grime and requires no frequent maintenance except for oil changes. This can be an ideal choice for those who do not want to spend too much time and energy on regular maintenance of their bike.
Operation of the Rohloff gearbox
The operating principle of the Rohloff gearbox is relatively simple. Its internal structure consists of three sets of planetary gears, the first two of which provide seven ratios, and the third a halved. This effectively doubles the number of gears to fourteen.
Shifting is provided by a handlebar-mounted bolt-on shifter with two cables that actuate an indexing mechanism in the hub, shifting up or down. When reaching seventh gear (shifting up or down), the hub changes from high to low (or vice versa), moving through the seven gears.
The indexing is controlled by a transfer box mounted in roughly the same place as the rear derailleur (on the opposite side). This receives the cables from the derailleur and transfers the rotational action in the box to the indexing mechanism inside the hub. The transfer case is easily detached by loosening the single hand-release screw to remove the rear wheel.

Maintenance and servicing
Oil change
The Rohloff Speedhub runs on oil and requires an occasional oil change. The manufacturer's requirement is that once a year or approx. change the oil after 5,000 kilometers. The hub contains 25 ml of oil, which you can buy from our webshop. Changing the oil is important for proper operation and smooth shifting. The oil change can be performed by anyone who knows the specific maintenance process of Rohloff hubs using the oil change set
Inspection and cleaning
From time to time it is worth checking the condition of the gearbox and cleaning the external surfaces. Check the transmission for visible damage, cracks, or other problems. Clean the exterior surfaces with a soft cloth or brush to remove dirt and grime. A small oil leak is normal, but you should pay attention to a larger oil leak.
