The Chris King R45 is a road version of King’s famous hubs. Since lightning-fast engagement isn’t quite as crucial on the road as it is when you’re ratcheting over obstacles on the trail, King cut the points of engagement from 72 to 45. Those 45 points of engagement, however, are still far more than most road hubs, and the R45 will engage and respond much more quickly than an average road hub.

  • Full-length, 17mm-thick axles
  • Less ‘angry bees’ than King MTB hubs

Here's what others have to say...


Make sure to know what you're buying!

    I purchased this hub 2 years ago not knowing what I got into until last week. This item definitely said that it's compatible for 11-speed but it's NOT!!!
    I was trying to fit my new 11-speed Shimano DA cassette but it doesn't fit!
    Like Marc R. said in the comments, I did pay an arm and a leg for the 11-speed conversion kit from Chris King since I had no choice.
    At this point, I'm very disappointed in the fake "advertisement" and all I got from Competitive Cyclist is "Sorry, can't do nothing about it" deal.
    The hub is very nice and all... but purchased from the wrong website...
    If you also check the Chris King official website, it does not state that this hub is 11-speed compatible!! Also checked several different sellers as well.
    Be careful with what you buy and fake descriptions!!!

    Two years ago was the 11 speed version came out, so there was a period of old/new stock. I would have to think it is all 11 speed for new stock. I am considering pickingup one soon as part of a rebuild.

    I'd like to see an update from CC to confirm the current state of affairs.

    Chris King made two versions of the R45 - 11 speed being the newer of course and they are visually identical. (The flange distance is actually different between models; it's not simply the 11sp conversion kit on the older hub.) The only way to tell for sure is to measure with calipers using the Chris King data sheet. (The difference is a matter of about 2MM.) I wouldn't necessarily trust a retail rep to know that degree of detail although they should have known when selling a $400 hub.


    Only one problem

    • Familiarity:I've put it through the wringer

    This is my second R-45 hub and it simply works, and works, and works. I like the fact that its not as "angry bee-ish" as traditional hubs and its weight helps build up some race worthy wheels. I have had to adjust the bearings once, which seems in line with most CK parts as the bearings break in a little. After the initial seating, I have not had to touch the bearings.The only issue I have it that the hubs last so long you won't ever get a chance to try anything else out because these hubs will still be rolling along years later.

    just chatted with CC. No, these ones are 10 speed only. Chris king has a conversion kit they will charge you an arm and a leg for, so that would not be worth it for most folks...

    Steel or Ceramic bearings?

    Steel or Ceramic bearings?

    The front R45 is listed as stainless steel. Would bet this is too.

    It doesn't really specify on Chris King's website either. Would assume ceramic is an upgrade though.
