Shimano Ultegra 6800 11 Speed Groupset

Description

The most popular groupset in the world can now be composed to suit your specific needs. All of the technologies previously found in the Dura Ace groupset has been used in the Shimano Ultegra 6800 groupset. The composition is basically up to you. All we do is help you out by preventing you from making incompatible choices. For instance, an 11-25 cassette won't optimally work with a long-cage rear derailleur, while an 11-32 won't work at all with a short-caged one! We have locked out these combinations for that reason. The choice of cranks is entirely up to you however.

The additional 11th gear and numerous improvements result in stunning performance. A lot of innovations of the new Dura Ace groupset have found their way to the Shimano Ultegra 6800 groupset. The shifter has a shorter lever throw for easier shifting and the group features a newly designed front derailleur and rear derailleur with a slightly different cable routing and completely new cable set. Also remarkable is the new four-arm crank. According to Shimano this design optimises the power transfer during your pedal stroke and is more rigid.

The 11-speed cassette is two millimeters wider than the old 10-speed group. The thickness of the sprockets remain the same, the spacers are slightly narrower. The result is that the 11-speed cassette only fits on wheels that have an 11-speed Shimano body. The brakes have been redesigned with a double pivot system, meaning two rotational points rather than just one. According to Shimano these brakes provide an improved control and stopping power.
