Freehub being chewed by the cassette

jimcameron

Hi,

With difficulty I took off my freehub today off my Zipp 404's. Once i got it off i realised why, the freehub had been chewed by the cassette, Do you think it would be alright to phile the burrs or do i need to get a new freehub body? I'm jsut worried that if i stick it back on again and it chews more then i actually won't be bale to get it off.

Cheers
Jim

You can file the burrs down, but you will want to get a cassette that has more support so that the load is spread throughout the freehub rather than concentrated on a couple of points.

Zipp have told me that i should get a SRAM cassette? Are they solid-one piece cassettes.?

They're machined out of one block, but they only apply force through the largest ring, so they should be fine.

the second pic here indicates this nicely.

only the very expensive openglide ones.

FWIW chewed splines is also symptomatic of a loose cassette lockring - filing off the burrs shouldn't be a problem, it's a fairly hefty chunk of metal.
