    Default Broken - Crank Brothers iodine hub!

    Hi Guys

    After some advice, on Saturday I was riding around on my new iodine wheels messing about and was pedaling up a hill when I heard a loud crunch from my rear wheel, this resulted in a instant loss of power and I thought that I had broken a chain (not uncommon for me).

    Unfortunately I discovered that the chain was intact and the hub itself was the problem, fearing the worst I pulled the hub apart thinking that i may have stripped the ratchet within the hub body itself.

    What I discovered eventually was the free hub (the pawls to be exact) and the carrier that they sit in had broken away from the freehub itself, meaning that with any input of power the cassette itself spun in the hub and did not provide any power at all.

    My question is has anyone had a problem similar to this before and can I fix it? I cannot seem to find replacement freehub bodies for sale anywhere and am hoping that this is the easiest solution. Otherwise as they appear to be two separate items (the freehub and the ratchet mechanism attached to it) can i remove and replace the ratchet assembly?


    Thanks in advance for any advice.

    If they are a new wheelset surely it would be warranty claim.

    Google it, very common problem and reflective of the reliability of much of Crank Bros products (but they sure do look good).

    If they are new why would you even contemplate the repair yourself - warranty job.

    The freehub system has a history of failing. There has been a newer version released (although at least 2 years ago) with more beefed up internals. The entire hub does come apart and is meant to, so that is not part of the problem. I had this happen and it was repaired on warranty as the wheel was meant to have the newer guts and didn't, but once since the spring holding the pawls in place broke causing the freehub to fail. The solution was simply using an old fork seal spring to replace the broken one.

    Yup a design flaw with the first generation CB wheels. Shortly after their release CB updated the hubs (freehub body) and the second gen freehubs are fine. Any LBS should be able to get one for you as Jet Black are the distributors and nearly everyone deals with Jet Black. No idea on price sorry.
    Yay! I found out how to put something in my sig!
