We've all got multiple cycling lives, ranging from racing road and 'cross to riding charity sportives and all the long training miles that go into preparing for them. Few cranks can comfortably straddle every aspect of the mutable cyclist's life like Shimano's Ultegra 6800 Crankset, which brings the stiff Hollowtech II design of Dura Ace to a price that appeals to riders outside of the peloton. The Ultegra 6800 Crankset may not be as light as the Dura Ace model, but it still checks in at a race worthy 765g. While the Ultegra 6800 drivetrain's two extra speeds may be the most noticeable upgrade, in truth, the entire crankset has been redesigned to follow in its big brother's footsteps. The biggest change is the use of a four arm, rather than the traditional five arm, spider, which saves a claimed 26g. The new crankset design also standardizes the bolt circle diameter, so it accommodates standard or compact chainrings without having to spring for a completely new crankset. You're able to switch gearing from a 55 42t down to a 46 36t in a matter of a few minutes.
