I knew about the smaller bearings, but just learned about the aluminum axle this weekend with a friend visited with a "broken" one. *When he took it apart in my shop he discovered that the end cap had stripped the threads in the axle. *I took a photo which you can find here: http://alexandchristine.smugmug.com/Bicycles/Shimano-XT-Aluminum-Axle/10997988_eTAGA#768940509_7GQHt The axle in the rear is a standard 10mm steel Shimano hub axle. *You can see that the thread pitch and the height of the threads is the same on each. He had not adjusted the bearings from the Shimano factory before having this failure. *I personally think that this is a silly place to save weight on a touring bike and would recommend LX hubs over XT ones for touring and commuting wheelsets. *Since the end cap is also used to preload the bearings it will not be fully threaded onto the axle. *In this case it looks like it was being held on with only two or three threads. I was disappointed to see this "development". *XT has almost always been light in smart ways, so that it ends up a little lighter than LX without giving up any durability. *Now it looks like LX is the durable group and My heavy duty city/tour wheelset is built on plain Deores. The bearing feel is phenomenal compared to even five years ago. The seals are magnificent. They just need a little touch of the cone wrench out of the box.
