Shimano Dura-Ace 7700 Freehub Body Replacement Compatibility

Seweryn

Hi All,

I am trying to find the freehub body replacement for a 7700 series hub. As it is an older model the availability is limited. Do you know if one of the Ultegra freehub bodies would fit? And what about the bearing and axle / cons?

Should be identical.

Thanks Shirley.

I assume it would have to be from the same period, i.e. 6500 Ultegra?
And are they sharing the same bearings and axle?

If youre having difficulty sourcing one, why not service the one you have? I know theyre not supposed to be servicable but they are.

Thanks David,

It is not the unit itself, but the cup of the bearing that is damaged. The freehub body itself may need servicing also due to heavy use / mileage.
