Shimano Ultegra FC-6800 50/34T 11-Speed Crankset

While it's traditional for Shimano to "trickle down" technology from its flagship Dura-Ace 9000 groupset into Ultegra, the Ultegra 6800 11-speed Compact Crankset received an absolute deluge of features Shimano's rock star line this go round. Like Dura-Ace, the Ultegra 6800 crankset has moved from a five-arm to a four-arm design which reduces weight without sacrificing one iota of strength and stiffness. Not only that, but the bolt circle diameter is now identical for compact as well as standard size chainrings meaning one set of crank arms can do it all - just swap out chainrings to mix things up instead of having to splurge on an entire new crankset. There's a hatful of hollow throughout this crankset as well - as in Hollowtech, Hollowtech II, and Hollowglide that all contribute to reduced weight and maximal stiffness. There's Hollowtech crank arms, a Hollowtech II bottom bracket spindle, plus Hollowglide outer chainring to deliver pro-level performance (seriously - the eagle-eyed pro cycling fan can spot Ultegra 11-speed components racing and winning at the highest levels).

This version of the Ultegra 6800 11-speed crankset features a compact 50/34T chainring set-up which is ideal for those seeking a wide range of gearing without the added weight of a triple drivetrain.

  • 4-arm design reduces weight without sacrificing stiffness
  • Same bolt circle diameter for compact and regular-sized chainrings maximizes crankset versatility
  • Hollowtech crank arms reduce weight and rotating mass without sacrificing strength
  • Hollowtech II technology integrates bottom bracket spindle into the right crank arm for stiffness and weight savings
  • Hollowglide outer chainring reduces weight yet maintains strength
  • 50/34 compact chainrings provide sweet relief on hillier terrain without sacrificing much top-end speed

    Comments about Shimano Ultegra FC-6800 50/34T 11-Speed Crankset:

    When I purchased my Trek Madone 4.5 I never liked the original tires or the Crankset. In July/2016 I purchased the Shimano Ultegra FC-6800 Crankset and
    I have been pleasantly surprised. I can pull the hills quite easily, it provides more power per the cadance performed and it provides a smoother bicycling experience. This is an upgrade that was well worth the price.

          Comments about Shimano Ultegra FC-6800 50/34T 11-Speed Crankset:

          I purchased this Ultegra crankset to replace the FSA set that came with my carbon bike, what a difference in speed by just upgrading the crankset and bottom bracket (Shimano BB as well). I have added a 1-2 mph difference on my rides as the pedaling motion is so much smoother and the cranset feels very responsive. I purchased this crankset for a climbing event I entered which covered over 13,000' of climbing and the 6800 crankset (50/34) performed flawlessly! I highly recommend the Ultegra 6800 but upgrade your BB as well, you will not be disappointed! Also, Nashbar shipped my order first thing the next morning and within 3 days of ordering my bike was in the shop having the new gear installed..Awesome customer service Nashbar!!!

            Doesn't get much better than Ultegra, and Nashbar has the best price by far. Great customer service and fast delivery. Awesome upgrade from my damaged 105 crankset. Thanks!

              Comments about Shimano Ultegra FC-6800 50/34T 11-Speed Crankset:

              Due to lower back issues and age, I am not a speed-focused cyclist. However, I still choose to keep up with younger, more aggressive riders and wanted more performance than I was getting from a triple crankset. The Ultegra FC-6800 crankset dramatically increased performance without sacrificing the ability to cruise/tour on a long ride. It is light-weight and responsive. Mechanically, it feels like a fine-tuned machine. Silky shifting, solid spinning. The fact that it looks great is icing on the cake.
