The Shimano Ultegra 6700 front derailleur features an improved cage shape reducing the need to trim the front derailleur. That means several shifts can be made in the rear without the annoying sound of the chain rubbing the front derailleur cage. The cage also has a wider inner link to increase rigidity and promote solid, crisp shifting. The spring in the 6700 front derailleur has 10% less tension for smoother shifting. This version is the newest glossy grey color that has a darker body than the previous finish.
