I need to replace the free hub shell that is on my wheel with one that will work with an 11-speed Dura-Ace cassette. The current one is for Campagnolo.

I don't want to take the whole wheel apart, I only want to remove the part that the cassette goes into.

enter image description here I took the bolt out.

  • What's the make/model of your wheels / hub? – alex Jun 15 '16 at 4:41
  • That's enough on some hubs but perhaps there's a nut on the other side that needs removing too. – Chris Jun 15 '16 at 7:44
  • If it doesn't just pull off, there might be a large hex socket in the axle bore that needs undoing (probably 8mm or 10mm). – Will Vousden Jun 15 '16 at 7:51
  • I'm guessing you're sure theres a replacement body thats compatible with Shimano for this hub, but just as a side note, you can interchange Shimano/SRAM/Campagnolo rear wheels for 11 speed in the other manufacturer's drivetrains and have something working: velonews.competitor.com/2013/09/bikes-and-tech/… – Batman Jun 15 '16 at 18:53

On the hub side of the freehub, there should be a Allen headed bolt that you need to unscrew. Some are 8mm, others are 10mm and some are 11mm. 11mm is a hard to find Allen wrench, so hopefully it's 8 or 10mm.
Put the Allen wrench into the center the freehub and unscrew in the normal direction (CCW).

  • @Suspended User Thanks for fixing my mistake. I use the two terms synonymously, but they are technically different. – Scott Lundberg Jun 15 '16 at 17:30
  • I understood and assume most would as well, but wanted to ensure it's correctness for search. Thanks! – Deleted User Jun 15 '16 at 17:33
  • Some unscrew on the opposite side to the freehub, in which case you need an extra long wrench. – Nic Jun 15 '16 at 21:22
