I've been trying to remove broken my joytech freehub (from an 11 speed felt b16) for a frustratingly long time. The model in question takes two 5mm allen keys, and is not the same as the seemingly more common one, which takes an 11mm allen key to remove, like these here and here

I have successfully removed what look to be seals from each side, but I am now stuck with two holes which receive a 5mm allen key, but that will not budge, to the point i'm concerned that maybe they're reverse threaded and don't want to apply too much force.

Here are two pictures of the drive side: enter image description here

and the back side: enter image description here

As i say, both sides take 5mm allen keys. Can anyone shed any light on how to remove this type of hub?

  • If this some sort of single speed or fixed gear hub? Commented May 29, 2018 at 21:12
  • @ArgentiApparatus nope, its an 11 speed from a felt b16 (road/triathlon bike)

    Ah, you're trying to remove the freehub body. Looks like you are at the stage of getting the axle out before removing the freehub. Commented May 29, 2018 at 21:51

    @Criggie The freehub is sticking, I'm thinking maybe its got some gunk in there and may be yet repairable. On the replacement note, I've alreade bought a new one, just trying to salvage a turbo trainer wheel :) Thanks for the advice, I'll give it some juice tonight and add an answer if i find one

    I did not notice you already have a spare. You could investigate the threads on that, couldn't you?

To answer the question, I had to give a sturdy tap to the axel from the back-side (though it looks like you could have gone from either end), which then popped out (leaving me able to remove the bearings) and left (what looks like) the 11mm allen key space to remove the freehub.

Update: you actually need a 12mm allen key (no need for the 11mm at all). You need to use the long part of the allen key (preferable keeping the short end in a vice) to loosen the larger interior receptor (12mm as opposed to 11mm, which is accessible from the drive side)

    Great work - thank you for coming back and providing updates. The park PH-11 is exactly the tool you want, but its not cheap. I'd try a 10mm to see if that fits - is a more available tool size if nothing else.

  • Ah, interesting. So to remove any freehub with sealed bearings, you first have to tap the axle and bearings out? Where were the 5mm keys needed?

  • @RobertLisaru as i remember; 2 x 4 or 5mm keys were needed to loosen the dustcaps (turn them in opposite directions) to allow removal of the axel.
