[no skid marks]

I'm after a lighter than stock BB for my XT cranks. and preferably more durable, but would rather lighter.
What options do I have, apart from the stock XT ones?
73mm shell.

Hope, King, Enduro. Not sure any are lighter than stock. With the Enduro ones you can buy the complete BB or just the bearings and install in your current cups. I have the Enduro bearings in my FSA cups. Work nice and I haven't had any problems with them. The lightest option would probably be a complete BB from Enduro with the ceramic bearings. I have no idea on whether or not they are durable. http://www.enduroforkseals.com/id224.html
