English thread freewheel to fit Italian thread hub?

[Robert McCormac]

I just purchased a NOS freewheel style Mavic 550RD rear hub sight unseen which the seller claimed had English threads. It turns out that they are actually Italian thread 35mmX24 tpi. Will I be able to fit a normal English thread Shimano freewheel onto the hub? I haven't tried because I want to be able to give it back without scratches for a refund if it doesn't fit.

35x24 is slightly smaller than 1.37x24, so you CAN (i.e., should be able to without any effort) screw an English threaded 1.37x24 onto your MAVIC hub, but you may (but, probably won't) "damage" the threads whereby you will probably only be able to use English threaded freewheels on the hub in the future.

Just remember to apply a light coat of grease to the threads.

Thank you kindly for the info. I tried it, and it fits!
