Shimano Ultegra R8050 Di2 Framväxel

The Shimano Ultegra R8050 front derailleur has been given a more compact design. The Ultegra R8050 front derailleur offers effortless shifts even when you're putting power through the pedals. The cage design has been optimised so that once the derailleur has been properly set up, the chain has no chance of hesitating or falling down on shifts.

Clamp needed?

On some bikes, there is no welding point for the front derailleur. To fit this front derailleur you can use a clamp.

• Compatible with the Di2 E-tube project
• Frame angle: 61-66
• Developed for race-specific frame designs
• Shimano Synchronized shift
• Total capacity: 16T

Reduce the tension on the gear cable.
Before you start (dis)assembly, switch the front derailleur to the smallest chainring. That way the tension on the gear cable is smaller, making it easier to remove the derailleur.

Disconnect the gear cable.
Use an Allen key to disconnect the gear cable from the derailleur. An Allen key can be found here.

Disassemble the chain.
Before you can remove the derailleur, you must also remove the chain. For this you need a chain tool or a missing link pliers. The chain breaker can be found here and the missing link pliers can be found here.

Position the front derailleur.
When installing, make sure to leave a gap of about 2mm between the outer edge of the derailleur and the largest chainring.

Adjust your derailleur.
It is important to properly adjust the derailleur after installation. This is a meticulous job, which you can read here.

Grease the pivot points for proper operation.
It is good to lubricate the pivot points and the cable with some oil from time to time. This keeps the front derailleur shifting smoothly. Good oils that you can use not only for this, but also for lubricating the rest of the drivetrain, can be found here.
