I think I have to discard the idea of using cg wheels as there is more to it than mere hub size.
I found on another forum that axle size, back and front sprocket alignment, width of swing arms and forks and much more to take into account for chaiging the wheel if it's to be done correctly considering both mechanical and technical requirements.
I am thinking to refurbish my wheels but here in UK it is not cheap.
If i bring wheels to Pakistan on my next tour, how much would it cost to get them re chromed? get the spokes to be re done for wheels to be straight? and to install new brake shoes and bearings. I will bring the bearings and brake shoe with me. Just someone to do re-chrome rims and polish/paint hubs and minor jobs like bearing installation etc.
