Ben Kuhnswrote a review of Shimano Ultegra 6800 Crankset on November 7, 2016
Familiarity: I've used it several times
While Ultegra 6800 is very much the sum of its parts, this crankset ends up playing a notable role in the overall performance.
While it may lack the shiny Dura-Ace looks and packs a few more grams, this is really is a top-tier crank. Construction delivers the level of polish you expect from anything carrying the Shimano name.
Paired with the Di2 front derailleur I have found the shifts to be fast and reliable no matter the situation. The shift up to the big ring is particularly impressive and at times so immediate I question whether the shift happened at all.
