Perhaps we'll now see a durable ISIS BB design. Wonder how much it will weigh?
SKF bottom bracket
Bearing maker SKF's new bottom bracket comes in a wide range of road and MTB options for ISIS drive and square taper cranks, and boasts some interesting features designed to make it a tough and trouble-free unit.
The bottom bracket has a one-piece outer shell to equally support both bearings, and newly-designed seals to keep out water - which SKF believes are good enough to provide a ten-year life for the unit.
The spacing between the bearings is as wide as possible to increase stiffness and the right hand side is a roller bearing which SKF says is capable of better handling the loads of the drive side.
A version with a beefier spindle - achieved by using a smaller bore - is available for mountain bike freeride and downhilling applications.

Samples are already out at some distributors apparently.
Here's a pict :
No indication of price as of date. Perhaps can ask if the people here are keen. But its no weight-weenie though.
