Shimano Dura Ace R9100 Front Derailleur

The Shimano Dura Ace 9100 Front Derailleur 11-speed is the successor to the hugely popular 9000 series. This front derailleur features an extremely compact design with the same fantastic lever function you've come to expect from Dura Ace. This new design opens up new cable routing options, and a major improvement is the possibility to adjust the cable tension using a hex bolt.

Require a derailleur clamp?

Some bicycles do not have a braze on for the front derailleur. To mount this front derailleur, you can use a derailleur clamp.

Technology

• Adapted to a race-specific frame design
• Integrated cable tension adjuster
• New link construction so you no longer need the TL-FD90 to determine the correct cable routing
• Total capacity: 16T
• Weight: 69 grams

Assembly

Reduce the tension on the gear cable
Before starting to (dis)assemble, shift the front derailleur to the smallest blade. That way the tension on the gear cable is smaller, making it easier to release the derailleur.

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

Disassemble the bike chain
Before you can remove the derailleur, you must remove the chain. You will need a chain breaker or missing link pliers for this. 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 2 mm between the outer edge of the derailleur and the largest chainring.

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

User tips

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.
