| Question:
|
How
does the drive work without a chain, crankset and the rear derailleur
sprocket gear system? |
| Answer: |
The
bicycle shaft drive system uses bevel gears front and rear with
a Nexus Shimano internally geared 7 speed hub. The shaft drive replaces
the traditional chain and crankset, and the internal hub gears the
derailleur sprocket system. |

| Question:
|
How
efficient is the shaft drive system? |
| Answer: |
The
performance of the shaft drive system ranges from 95 to 99% efficiency.
In comparison, a high performance well maintained chain system ranges
from 95 to 97% efficiency. Due to exposure to dirt and the elements
however, the efficiency of a chain drive will reduce more dramatically
over time than the shaft drive system. |
