Token MTB BB's for 68/73mm shells. They come in pretty anodised colour and are quite durable. The best bit though (if you have the tools and The Cycle Clinic does) is the the 6805 bearings are entirely replaceable as the plastic cap comes out without breaking. This allows you or a us to put 6805 INA bearing in there and is of course inspired. So for £20 the Token BB is the best bottom bracket on the market for hollow tech II, race face and other compatible 24mm spindles cranksets inlcuding XTR, Dura Ace no matter what Shimano might try and say.
Weight is just over 100g.
