Turbo-charge your bike with ceramic bearings. Compared to steel bearings, Ceramic Speed Silicon Nitride (Si3N4) bearings reduce friction, decrease power loss, reduce weight and lengthen service life. They are also less susceptible to dirt, dust and poor lubrication. Specify Campagnolo or Shimano.

Shimano Dura-Ace 7800 Rear Derailleur

List Price: $159.99
Our Price: $119.99

For double gearing configurations
Weight: 180 g.
9 or 10-spd compatible

The Shimano 7800 10-speed rear derailleur features a wide link design that is lighter, more rigid and durable. The increased rigidity stabilizes the chain as it glides up and down the sprockets. Less play means rear indexed shifting is not only quicker, more precise and reliable, but it also insures better indexing over many more road miles. The reduced flex not only creates a more solid shifting system, it stays solid a lot longer. Sealed bearings in both guide and tension pulleys.

Minimum Sprocket: 11 tooth
Maximum Sprocket: 27 tooth

List Price: $179.99
Our Price: $174.99

For triple gearing configurations
Weight: 192 g.
9 or 10-spd compatible

New wide link design is lighter, more rigid and durable. The increased rigidity stabilizes the chain as it glides up and down the sprockets. Less play means rear indexed shifting is not only quicker, more precise and reliable, but it also insures better indexing over many more road miles. “It shifts like a brand new derailleur, even after 5000 miles,” is how one pro-racer described it. And it’s true. The reduced flex not only creates a more solid shifting system, it stays solid a lot longer. Combined with the new SP41 silicon grease injected cable housing, RD-7803 adds key advantages: lighter weight and crisp, instantaneous shifts that are 10% more efficient from lever to rear derailleur. 9 or 10 speed cassette compatible.

Minimum Sprocket: 11 tooth
Maximum Sprocket: 27 tooth
