- Gear ratio comparison: Speedhub vs derailleur drivetrain. (German)

- Efficiency comparison: Speedhub vs derailleur drivetrain. The Speedhub has a overall efficiency of 97%. Higher gears have a higher efficiency. Above the Speedhub gear 8 the efficiency is higher than a derailleur drivetain. (Gears on X-axis (bottom); left side expansion in meter per crank turn; right side efficiency in %; Red line Rohloff Speedhub; Blue line derailleur drivetrain with yellow dots 22 teeth chainring, green dots 32 teeth and blue dots 44 teeth; the upper two lines show the efficiency; the lines on the bottom the expansion per gear)
- Living with the Rohloff Speedhub: The article is the best resource I found about the Speedhub. Very detailed! The article also mentions the max. input torque for the hub. This is important to define the starting point of the 526% overall gear ratio!

I have a Rohloff speedhub nowe, for quite a couple of years. Surprisingly, you can feel the high efficiency of this hub. But to be honest, I am not so happy.
First, when I instaled it on my Flevobike, very often after changing gears, the hub switched to “no gear”, free running pedals without power to the wheel.
There is only one type of “lever” available for changing gears. The force to change gears is relatively high. Sweatting a lot I failed to change gears when I needed it most, my hand, wet from sweat slid several times around the lever, until, after a few attempts, I changed two gears instead of one.
Very often, after changing gears, I need to play the lever until the wished gear is engaged.
It is fascinating to be able to switch all gears with one lever, even when standing. But changing gears does not work that reliable. One would expect a good working equipment for that price.

With regard to the Rohloff Speedhub you claim that:
“Above the Speedhub gear 8 the efficiency is higher than a derailleur drivetain.”
I have a Rohloff and I love its convenience, but the above statement simply isn’t true.
A derailleur drivetrain consists of one chainring and one sprocket.
A Rohloff drivetrain consists of a chainring, a sprocket and one or more sun/planet gear combinations. The meshing losses, plus the small amount of loss associated with friction of lubricants and seals mean less efficiency than a derailleur.
The Rohloff is without doubt an engineering meisterwerk, but it is still a hub gear. And hub gears may be more convenient to use, be more reliable long term, and long term, cost less to run. But they are still less efficient than derailleurs.

We have hub number 003, which has nev er yet been built into a wheel, but we are going to incorporate in into a ike very shortly. I hope it still works after all these years!
Incidentally, it came our way because it was the hub which was sent to Encycleopedia for photography purposes, when the Rohloff was launched. It was passed to a mechanic as payment for something, and when he retired, we bought all his shop stock. A year later, he found the Speedhub, so he gave it to Berine for her christmas present!
