It's the new Shimano Ultegra 6800 and it's causing a stir. This updated front derailleur features the same technology as the pro-level Dura-ace. Like Di2 front derailleurs the mechanical braze-on version of the FD-6800 has a new 2mm hex support bolt that stabilizes the front derailleur against the frame by providing an extra contact point. The FD-6800 also has a trim feature so it can be fine-tuned to be quiet in all gear combinations.
