[Closed] P clip pannier rack mounting + Charge Mixer

Hi folks,

I'm looking at getting a charge mixer for commuting and playing about on, although it has abolsutely no mudguard or rack mounts...

Charge claim to make a bracket that will allow you to fit a mudguard, anyone used it?

Also they recomend using p-clips to mount your rack. Doesn't this dramatically reduce weight carrying capability? I do my weekly shop and often have 10kg hanging off one side of the bike, this doesn't sound like a good idea to me??
