Anyone heard of these?

or have any experience of either? The weight figures seem good but can't find any reviews on ride or quality. I expect spares could be difficult?

Bearings would be run of the mill. I thought Selcof made real budget stems and seatposts many moons ago. Personally I would go for wheels which you can get spokes, freehubs and bearings.
