I know this has been discussed before that the right dustseal you get with the Hyperglide RM-30 freehub doesn't fit the Uniglide axle cone when you do this conversion, but according to Wheels Manufacturing the correct cone for this freehub isn't available any more. Does anyone know of a cone that would work: it apparently is 16.9 mm in diameter and 15mm long?

The other thing I've thought about doing - which is kind of rough and crude - is to just enlarge the opening in the dustseal with a die grinder until it fits the UG cone, in which case the cylindrical part in the middle of it would get ground away. Or another idea would be to pack the end of the freehub full of grease and count on this plus the lockring for the cassette to keep the dirt from getting to the bearing and just go without a dustseal.

Thanks for any information.
