How many times do we tell bocking noobs this?
THE KNEEBAR IS NOT FOR PROTECTION.It is merely there for comfort, rather than having metal rubbing on your leg. If you fall it provides no cover for your kneecap and it will still slam into the ground.
Like ET Said, Dave, Calm your posting and get reading and researching. Otherwise we'll just all laugh when you come on here going "I have no kneepads and I smashed my knee in!". Well ET, BmthBloke and Me will anyway, we're a real sympathetic bunch
