Like Dura-Ace 9000, Ultegra 6800 offers a more extensive scope of adapting choices. The new standard back derailleur lives up to expectations with tapes from 11-23 to 11-28, while the new Ultegra GS mid-confine back derailleur permits riders to run a 11-32 tape, a peculiarity that Dura-Ace does not offer. Also obviously there is that additional ratchet.
That broadness of decision is additionally found in the new Ultegra 6800 wrench, which uses the same four-arm insect and exchangeable chain rings first seen on Dura-Ace. That implies you can run 53-39, 52-36, 50-34, or even 46-36 outfitting on the same wrench.
The trickle down is additionally seen in shifter ergonomics, which Lawrence says is the most observable change from the 6700 gathering that was discharged four years back.
Shimano asserts that obliged Ultegra 6800 lever toss energy has diminished by 13 percent. The part creator additionally updated the front and back derailleurs, and included another polymer covered link set to further facilitate the power needed to move the chain around. The new front derailleur has the same longer lever arm of 9000, which as indicated by Shimano, lessening front moving exertion by 35 percent over the past era. The new gathering likewise has 10mm of lever achieve conformity to consider cockpit customization.
There are two different regions of the Shimano Ultegra groupset arrangement that are well worth specifying. In the first place the brakes are heavenly, being loaded with force but likewise being not difficult to regulate. At that point there are the spd-SL pedals. Typically in light of time obligations I swap my trusty Look Keos onto a test bicycle, however as this bicycle was with me for rather more than ordinary it provided for me the opportunity to set up a couple of shoes with Shimano spikes and utilize the carbon Ultegra pedals.
From the get go they felt somewhat precarious to captivate, on the grounds that the front bit of the fitting need to drop down through the opening in the pedal instead of being gotten by a lip, yet you do get used to this and once found there was an incredible suspicion that all is well and good, firmness furthermore soundness over the expansive primary contact patch.
