Spanish ‘BB 2’ ?

Spanish BMX company, Fly Bikes, are currently testing an updated version of their ‘spanish’ bottom bracket. It is still unclear, what significant changes have been worked into the new design, however the Fly website carries an article on the testing, which states that bearing sizes have changed several times.

The article has close up shots of the design, which unlike existing BB’s, incorporates an Allen key clamp into the shells casing.
