Velosolo bolt on cogs

has anyone had any experience of using hope pro 2 hubs for this?

i want to try this out and i'd rather use a hub with cartridge bearings but appreciate that the axle will be different and din't know what complications this might cause..

Cup & cones will work fine. The M756 is forged rather than CNC so it is tougher than most other alloy hubs out there, as well as being built to take a serious beating off road so it should spin for years and years if you look after it. By that time you'll probably be riding on different wheels anyway.
