With the Crane, Shimano pulled out all the stops in an attempt to make a truly world-class derailleur. It was an all aluminium design with a dropped parallelogram - a world first.
The pulleys had a two part bushing system so that bronze rotated on bronze. Even the springs seemed to have less of a tendency to lose their tension. |
Condition: Used. Very Good Condition. |
