The Shimano Dura Ace 9100 front derailleur is now more compact, lighter and, above all, even more efficient than the previous version.
The derailleur has an internal toggle mechanism, allowing the use of wider tires.
It also integrates an Allen screw that allows you to adjust the cable tension. It will therefore no longer be necessary to use a tension adjuster on the housing.
Features:
- Upper chainring teeth: between 46-55 teeth
- Chainline: 43.5
- Total capacity: 16 teeth
- Bottom pull
- Mounting: braze-on
- Faster and more precise shifting
- Tension adjustment screw on the derailleur
