Got my working wheelhorse out today, first job was to fit the refurbished rear wheels, change the standard seat for a heavier one and fit the wheel weights.
taken off.
two standand wheels 52lbs.
standard seat.............11lbs.
fitted on.
two narrow wheels 48lbs.
seat........................37lbs.
two rear weights.....100lbs.
so total extra is 122lbs, I'm pleased with that and should help with traction
