A trickle-down torrent.

In the case of the Shimano 105 FC-5800 11-speed Crankset, the term "trickle-down" should more aptly be replaced by "deluge-down." The new 105 crank employs so much of the technology and performance of its more expensive Ultegra and Dura-Ace siblings that it begins to look a bit like cannibalism, and that's a great thing for you if you don't want to drop major coin on a crankset, but still want great stuff.

Replacing the 5700-series family of 105 parts, the new 5800 group steps up to 11 speeds, and its performance is now on-par with that of Dura-Ace from only a few seasons ago. That's pretty remarkable. So how does the 5800-series crank do it? Most notable to the eye is the adoption of Shimano's new 4-bolt spider and chainring configuration. Not only does the new design simultaneously lighten and stiffen the crank, it means the 105 crank now comes with only one bolt-circle diameter (or BCD) measurement — as on Ultegra and Dura-Ace. Now you can have its chainrings swapped out between the available 53/39-, 52/36-, or 50/34-tooth combinations without needing new crank arms. Also along with Ultegra and Dura-Ace, the 105 chainrings are now constructed using carbide elements that lighten them while also boosting their rigidity for greater power transfer, durability, and more precise shifting.

The Shimano 105 FC-5800 11-Speed Crankset is available only in the color Black. It comes with arm lengths of 170, 172.5, or 175 millimeters and with 53/39-, 52/36-, or 50/34-tooth chainring combinations. A bottom bracket is not included.

  • Aluminum arms
  • 4-bolt spider/chainring configuration

Keep on Pedaling!

    THe 105's last forever! Sure they are a bit heavier but i don't care as it is on my commuting bike. Love Shimanos products. High quality, smooth and keeps you spinning all day long!

    105 = Awesome

    • Familiarity: I've used it several times

    I bought this crank as part of a 105 groupset to put on a spare frame I had laying around. I decided to go with 105 because the 105 has had a history of being Shimano's workhorse group and this 11 speed group is priced great, which leaves money for wheels or cockpit parts. Every component within the group got a good upgrade and resembles features found on the higher priced 11 speed Dura-Ace and Ultegra groups. The 105 groupset also allows for a pretty easy gear configuration if you're interested too (11/32 cassette, long cage rear derailleur & a 50/34 crank). If you're on a budget or want a group for a training bike, the 105 11-speed group is no-brainer option.

    Heavy duty, smooth shifing, stiff, reasonable price. Great all rounder especially on a budget.

    The black powder coat seems to come off overtime especially when you get derailed.

    Underrated performer

    If you're on a budget but need a quality groupset, 105 is great stuff. It looks awesome in black and functions at 98% of it's more expensive cousins. There's a weight penalty with 105 for sure but the value is impossible to beat.

    Awesome crank for a newbie

    • Familiarity: I've used it several times

    I am not in a position to pony up for a top end drive train. This is perfect though for what I hope to be a year round commute. The crank is solid, the chain rings are nicely geared and it'll stand up to crap weather and abuse. I ride terrible roads and will put a lot of wear and tear on the bike in the next couple of years. The 105 should live up to the challenge.

    works great, just heavier than dura ace

    • Familiarity: I've put it through the wringer

    shifts awesome, stiff, relatively light

    will shimano 105 fc-5800 11 speed crankset work with kestrel 105 legend road bike. it now has oval concept 520 compact 52/36t that I want to upgrade

    Rommel, Your bottom bracket is probably a BB30. So with adpaters, this crankset will work.

    Will this crank work with my 105 5700 FD, RD and chain?

    Best Answer

    There shouldn't be any big issues, you may get some slight chain rub as this is meant for 11 speed chains. But it will work with a proper installation.
