OK, if seeker333 is correct that larger bearings are more ideal for loaded touring, then the technical documents by Shimano show the LX 660 rear hub had 9 bearings and the XT770 has 13 bearings.

If this is really true then I guess it's case closed. That's nice to know for me since I'm the one usually asking myself a billion "useless" questions. But, I saved some parts for a future project and don't have a frame or the wheels for that project yet so... hehehe

I believe this does make sense though because LX is now intended for trekking. But, I do believe Niagaracycle sells the 660 LX. I also know bikexperts in germany sells even the dynamo hub in LX.

wow, that's strange, I couldn't find the 36 hole...
