as it turns out , the end bearing in the freehub is just to crap to put it straight, its too small, they have adressed it and will be changed in due course, they did conisder a bushing being used, but have opted for a taper roller bearing. bit of a shitter really, mark, they didnt spend ages developping bearings they were just awaiting delivery. also leaf springs have had a slight change, the size of radius has been altered to a greater size to stop them snapping, they now seem ok after running them. ash
